??? for fox body guys

[Camaro_Dave]

whats the best wheel tire size for the rear of a stcok 91 notch mustang?
can you fit 15x10's under it? it has the 4 lug axles btw. do they make pro stars in 4 lug? i know they make draglites.
tires would be bfg drag radials. or maybe even the mt dr's??? i dunno.

thanks

[TC89LX]

A 15x10 will fit with a 6-6.5" backspacing. The common Draglite/Prostar will have the 6.5" BS and will require lip rolling and some inner tub "massaging" to fit. Depending on the tire size there may even be a small spacer required. I used to run a 325 50 15 BFG on a 15x9 (5.5" BS) in 4 lug and it worked out and fit very well. Then I converted to 5 lug and went to a 10" rim and at the same time swapped to the MT in the same size. The MT is a bigger/wider tire so I have to use a 7/16" spacer to get enough inner clearance, although I could probably get away with a thinner spacer. It likely would have fit well on the 9" rim though.

A Draglite is available in the big widths in 4 lug but the Prostar is strictly 5 lug. Prime wheels used to make a 4 lug Prostar copy but not in that width.

sweet thanks.
sweet lookin car!

[TC89LX]

Thanks!

[Camaro_Dave]

ok bringing this back from the dead. i just bought a 92 notch.
to fit your 325 with a 10" how much "massaging" did it take? it has dr's on it now but they are 275's. the car has a Southside suspension, UPR torque box reinforcments, Flaming River manual rack, etc. what else am i going to need to make this thing hook on a dr? its going to have a 415ci 18* sbc with nitrous blah blah. and it'll have an automatic. i kinda want ti keep full interior but we'll see how much is left after the cage and stuff goes in.
the engine was going in a tubbed ladder bar camaro but i changed my mind. i think this will be more fun anyway!!

thanks for the help!

[TS 27's Old Man]

8lb Sledge and adjust to fit;)

[TC89LX]

Yup, rolled and flattened lips. Very well massaged inner tubs using a very large hammer. Fit it up, see where it needed it and kept beating until it fit. I still run the thin spacer and haven't really had any issues with then.

Getting it to hook? I've had success with a 3.73 rear gear and Powerglide with my 408W and nitrous. On a good track I was able to give it right out of the hole and did a string of 1.35 shorts on the radials, 4 in a row within .003 of each other. I set the 2 step low at 3600rpm and let it fly off the T'brake. Currently my best pass on the radial tires is a 9.52 @ 141. Considering my currently slick pass on a bit more spray is a 9.44 @ 142 I'm pretty happy with how they've hooked for me. I find I need a pretty decent track surface though, my slicks will hook on just about anything but the radials are a bit more finicky.

[Camaro_Dave]

awesome! so is a 315 going to fit instead? its a little taller right? i've always been a fan of the taller tires i guess...

what shocks and stuff are you running? and what other suspension mods? i don't really expect to go any faster then a mid 9 fwiw

[Camaro_Dave]

ok....well i've been browsing around turbomustangs and seen a few more pics of a 325 w/o being mini tubbed, thats not my style. i like a good tucked tire. couldnt really fins anyone running like a 295. my 275's just look tiny. but the 325's stick out too far.

do you have a rear shot of your car?

[Camaro_Dave]

well i guess it helps to look a m/t website ha ha. i guess that people aren't running the 315 and 295's cause they are 30" instead of the 28"....man i need mini tubs.

[TC89LX]

They do hang out a bit, a narrowed rear end and mini-tubs will get them under. The 315 60 15 's are monsters at nearly 14" in section width and 30" tall. That is my ultimate goal to get a set of them under it but it'll take some work. If I could tuck them I would, but I can't just yet.

On a good working car the 275 60's may work just fine. One of my friends has been 9.40's on his in that size. Low 1.4 shorts.

My suspension is Lakewood 90/10's up front with a 130lb/in 14" coilover conversion. Out back is 50/50's from Lakewood and stock sprinsg. UPR solid lowers and double adjustable uppers and an Wolfe Racecraft anti-roll bar.

mine has a 275 50 15 right now. would i gain anything going with the 275 60? its on a 8" wheel. the tread is smaller on the 60 right? and i'm guessing the 295 is too tall also. i'm just used to running a 31-28.4-15 in my camaro so these DR's look tiny ha ha

[Camaro_Dave]

and can i mini tub it and keep the rear seat?

where did you get your hood? i'll need a 4 inch and i want an extended. but i don't like the rounded edge ones. yours looks more square. is it?

thanks!

[Camaro_Dave]

ok. would it be ok to run a 10" wheel with a 275? its on an 8" now but looks like it pulling the tire in a lot.

[dmc_racing]

ok. would it be ok to run a 10" wheel with a 275? its on an 8" now but looks like it pulling the tire in a lot.

A 275/60 should be fine on a 10" wheel. I'm not so sure that I would do it with a 275/50 ... the sidewall is already short, though it may still work. If you could see a 295 on a 10" wheel, you may like that as well. May not be as bad as you think :)

[Camaro_Dave]

295 is too tall. and i am buying the 60's now that the 50's are worn out. so i was going to buy a 10" wheel....

[Camaro_Dave]

should a 28-11.5-15 hoosier quick time pro still fit if the 275-60 fits? all the numbers look about the same...

[Camaro_Dave]

sweet. i have a 15x8 5.5bs wheel now. would it be better to go with a 15x10 6.5 bs? never ran the car but looks like a 8" wheel is too small for even the 275-50 thats on it...
did you trim or roll the lip?

thanks for the help

do you have any other pics of you car? i want to see close ups of the rear tires. like how far they stick out and maybe a shot from the rear? i plan on mini tubbing it in the next year or 2 but until then i still wanna run the biggest dr i can. so i think i might order the 325's. but i just want to see pics before i totally decide.

thanks!

Massage, I thought iresearched it enough, and bought some 325/50/15's and had them mounted on my 15x10 w/6.5 BS.I thought they looked wide, but tried to mount them on my 87 notch. Massage?!?! How about beat the car to death until the trunk floor starts to crinkle. NO WAY IN HELL ON A 6.5 BS unless you really dont like your car. I tried to stuff the 325/50's under there and it anit happenin unless you like your tires sticking out 3-4". Here are some pics of the 275/60 MT's under my car...... *Slight* Massage to make them fit witout rubbing around the spring. Hope this helps. I like the look of the 325/50's but you will seriously have to BEAT YOUR CAR TO DEATH to make them fit without MINI-TUBS.

Hope this helps, Rudy

They definitely aren't tucked under the car fully but with the anti-roll bar in place there isn't enough body roll to rub the tires 99% of the time. I can get the same size BFG in without a spacer, but the MT tire is too close for comfort so I chose a small spacer. lt's been working well for me.

[Camaro_Dave]

thats a big tire!! i wish i just had the money for mini tubs right now. i guess i could make it hook with the 275-60's. i'm just a fan of tucked. my camaro has a 31-18.5-15 under it and the tire is tucked inside the outer fender like 3 inches.
i guess i'l flip a coin and decide ha ha thanks for your help guys.

[Camaro_Dave]

one more question. have either of you had problems with your pro stars and busting wheel studs?
thanks

[BruceO]

Here a shot.thats 325/50/15 on there.

[TC89LX]

Haven't had a wheel stud issue at all with both my old Draglites (ran for 4 years) and my current Prostars which have been on almost 2 years now. I did upgarde to 5/8" studs out back when I did the 5 lug conversion though but haven't heard of any issues regarding studs and a Prostar at all. 2 of my friends run the Prostars on a stock 1/2-20 stud without problems as well.

i'm liking how the et streets look! but i think if i was going away from dr's i'd get the hoosier 28.11.5 qtp. has more tread width with the same section as the et doesn't? i'm torn on which way to go...

[TC89LX]

The Hoosier 28x11.50 is a bit taller and definitety wider than the same size MT ET Street. More comaprable in size to a full 28x10.50 slick.

[Camaro_Dave]

i'm new to the mustang thing. i know you can tub it a little and keep the shocks in stock location. is the price big to move to coil overs more towards the center of the housing? i know you would need something at the top to mount the coil overs to. but how do you know where to put all this stuff? if mini tubbing it is only going to cost me like 5-600 bucks i'll do it this winter. but if its more i'll have to wait.
would i have to cut out the trunk floor to mini tub it or just cut out where the actual tubs go?
i want to cut the car up as little as possible! but i also like a tucked big tire look.
thanks

[BruceO]

Dave, you could put a mini in there with the stock shock location but why?the shock is whats stopping the tire from going in where it needs to be,along with a few other spots .u could just beat the stock tub to hell and get that much more clearance.if u gonna mini tub it put the coil overs on.you dont have to remove the floor to coil over or mini tub it.just a lil trimming for the tub.if the car is real low u might have to bring the shocks in the trunk area a lil.i cut my trunk out to put a fuel and water cell in it but u dont have to.

[Camaro_Dave]

so where would i mount the coil overs if i didn't cut the floor out? and where on the housing would i mount the coil overs? if its only going to cost me 150 for the kit and maybe a little custom bracket for the shocks then i'll order the kit today.

[BruceO]

At the top i mounted it to the rear cage bar.on the housing u will have to figure out what all u are going to put on there.u will have shock mounts,wheelie bar brackets?anti roll bar mounts? heres a pic of mine where its mounted on the top and on the housing.

[Camaro_Dave]

thanks for the pics

[95silverstallion]

Hey Bruce, Where did you get those upper control arm mounts on the housing? I've thought about trying to fab something up like that. Did you fab them? They gotta help big time for IC set-up

[BruceO]

Hey Bruce, Where did you get those upper control arm mounts on the housing? I've thought about trying to fab something up like that. Did you fab them? They gotta help big time for IC set-up
I got them a few years back from a place in Ky i beleive.cant even remember the name.they worked great when the car was at stock ride height,but since i mini tubbed it and shortened the rear housing and can tuck the tire in and lower it to the ground i had to go back to the stock location. i just made adjustment holes on the front mount.

thanks for the reply are you using drum brakes or disc on rear?

[TC89LX]

Rears have been converted to the 1994+ rear discs using offset brackets from www.northracecars.com so track width increases were minimal, 1/8-1/4" total maybe.

[Camaro_Dave]

what back spacing front wheels is best for a fox(15x3.5")? don't the pro stars only come in 1 3/4"? and i know those fit good. so should i stick with the 1 3/4 or is the 2 1/4" better (different wheel of coarse)

[BAD INT]

13/4 wider is better more stable

[dizope]

Dave, I'm glad you are asking all these questions because I plan on the doing the same stuff to my 87 this year.

At what point is the 8.8 not suitable anymore? Why not just build a 9" from the beginning?

[Camaro_Dave]

from what i've been seeing the 8.8 can handle quite a bit.
things ive been noticing is welding the tubes right by the housing, braces, 9" ends, good diff cover, spool, and good axles.
i'm sure there is probably more tricks but those are the usual i guess. i'm only hoping for mid to low 9's so i hope i'm safe ha ha

[dmc_racing]

When welding the tubes, make sure the housing is in a jig or the tubes can "pull" on you. I have seen it done without any type of jig, but you are taking a big chance. At the very least, I would brace it then weld the tubes. If you use a threaded brace, don't put any tension on it one way or the other. This may help from pulling the tubes. If you're doing the 9" ends (which isn't totaly necessary), this would be the time to weld since the housing will be in a jig.

The 8.8 is a tough unit. You'll be fine at this level.

[dizope]

Thanks guys.

[Camaro_Dave]

good info. thanks

[Fryguy302]

Cool pics on here. Mine was just mini tubbed also. I used to run 28x10.5 MT slicks on a 15x10, 6.5" backspacing. That took some hammer work.

I was told to stay with the 8.8 because it consumed less power than a 9". Here's a pic of mine mini tubbed, narrowed approximately 2" each side. This is with stock style contol arms still but coil overs. Also this shot is with 15x12" wheel and 28x10.5w tires.

Sorry the pics suck, they're just phone pictures. That last pic is with the same size tire but a 15x10 with a 4.5" backspacing.

[Camaro_Dave]

so i was tring to order pro stars but EVERYWHRE i tried said they couldn't ge them tll april. so i just bought bogart front wheels :) now come to find out that the rear bogarts are like $460 a piece. so i think i just want to get aluma stars. i bought the hoosier 28x11.5 qtp's. i want a 10" wheel.....but they only come in a 6" bs not a 6.5" is it going to make it hit worse on the lip with the 6"? or should it fit fine?

[Camaro_Dave]

nobody??

[Fryguy302]

It will hit a little worse on the lip with a 6" backspacing, the 6.5 is almost perfect. At least it will clear the inside better, it takes a lot of hammering with a 10" and 6.5 if everything is stock.

I bet it will still clear though, that tire is smaller than a regular 28x10.5 slick isn't it?

[Camaro_Dave]

well i hope it doesn't look too retarted with bogart fronts and pro star rears ha ha.
ordered those for now.

[Camaro_Dave]

Haven't had a wheel stud issue at all with both my old Draglites (ran for 4 years) and my current Prostars which have been on almost 2 years now. I did upgarde to 5/8" studs out back when I did the 5 lug conversion though but haven't heard of any issues regarding studs and a Prostar at all. 2 of my friends run the Prostars on a stock 1/2-20 stud without problems as well.


so i ordered pro star rears. and i ordered axles as well. ...anyways did you have to change anything going from a 1/2" to 5?8 stud to fit the wheels? i'm guessing the wheels still fit, cause don't they only make 1 size hole for the pro stars?

[TC89LX]

Nope, the wheels fit very snug onto the shank portion of the 5/8" stud at first but after a few times on and off i think it has knocked the burrs off the inner aluminum pieces of the wheel. They slide on pretty well now, still a snug fit but that's a good thing. I like the 5/8" studs, wheel is on and centered and then it's just a matter of sliding the washer/spacer on the sud and torquing the flat faced lugs down.

The 28x11.50 Hoosier QTP should fit very well on that rim set up.

[qwiknotch]

I wish I would have seen this sooner...

I ran 4 lug on my car and it ran low9's @3200.
Holeshot 15x9 rears with a 5 7/8 b.s Didn't have to hammer too much and I fit a 28.10.5 slick or 28/12.5 Et Street.

needin rear brakes now. i'm looking on the site, did you just get the "5-Lug SN95 Rear Disk Brake Conversion (10.6" Rotor)" for $160?? or is it something else? i know i should call them but its sunday and i'm intersted to know ha ha, but these will work with c clip eliminator moser axles won't they? i got the 5/8" studs so i'm guessing i could just have them drilled out to fit?

Yup, those were the brackets I used. I sourced new rotors and pads locally and scored a set of rear calipers and brackets cheap off a friend. I had no issues at all with their installation and they worked out better than expected with the C clip eliminators. It did move the wheel out maybe 1/8-3/16" per side due to the thickness of the rotor but that never caused any problems for me, actually it helped out on the tight inner clearances. I also have 5/8" studs, drilling the rotors iout to 11/16" allowed then to slide right on.

It worked out very well, I'm pleased with it for such a low buck conversion.
