I have a C4 Corvette. Had the same problems and same options for suspension. Last year I had my chassis builder build a subframe (bolts in to the factory suspension mounting points) and I went with a S197 Mustang 3 Link.

Dominic Chimino at DC Performance in Baltimore MD did the work.

Not that I don't like the F Body TQ Arm... its a good suspension and it works really well. Big draw backs to me were - Number 1 everybody else does them.... and number 2, they take up a lot of room in the tranny tunnel..... I had rules that (at the time) required exhaust systems to be run past the driver and under the car....

We (my chassis builder and I) talked at length about using a F Body TQ Arm, G Body or Fox 4 link but I just really liked the S197... it's a touch simpler, with so many Cobra Jets out there hauling the mail I knew I could make it work... and if we couldn't - I could convert it to the tried and true TQ arm very easily.

My car has been 1.20 60ft straight as an arrow leaving like grandma.... Pretty good for right off the trailer after a bunch of changes and missing half the season after torching the motor first race out with it.... This year I am putting the wood to it.

I have a few pics of the construction here in my Photobucket:

I know my guy also converted a ladder bar suspension under a Mitsubishi Conquest into a Fox type 4 link I believe back in July....

The newer mustang was also an option too. Nice to see pictures to get a better idea on the frame Ill have to build. Are the lowers and upper the same length as s197 or is it custom length?

 

Welcome. Being a longtime lurker im sure you know the deal. This car gets it done with and IR set up

If it were me? i'd start with a T-bird IRS 8.8 center and go from there

 

That drivetrain cost 20k+ which is what I have into my entire car. I cant justify spending that much money for something I dont class race. Im picking up an 04 8.8 this week with disk brakes etc for $200 locally.


For some reason when I quoted B Williams it doesnt show. Did you use the same lengths for upper and lowers as the S197 or is that custom as well?

Upper and lowers were fabricated out of CM and are whatever lengths were needed to fit under the Corvette. They are shorter than the factory S197.

If your not class racing and required to use "Stock Suspension" why not just use a regular 4 link? Easy to fabricate... you can believe if I could have done that - I would have.

You can do the glide or t400 using a c6z or zr1 rear with 3.42 gears.. It cost more then a nice 9" center to build one tho..

 

I have a z diff and already cracked it once. As stated the irs9" and glide from rpm and the spindle kit to run 15s is 20k

I do my own fab so I can built a solid axle setup with built glide for under 7k

Everyone I talked to told me not do a regular 4 link unless I want to spend lots of time trying to tune the suspension since out of 50 adjustments, only 2-3 might work.

 

Bringing this thread back since its getting closer to completion on the new turbo kit.

Thoughts on using a 4 link kit similar to this? http://www.checkeredracing.com/4Link4Bar.html

First plating the stock rails then welding the 3x2 cross bar between it? Then adding tubular support from the where the stock subframe bolts up to the cross bar(should eliminate twisting?)
