Would like to get a few thoughts from the group... I was running my 68 fbody with 200lb Santuff springs, smith racecraft arms and viking DA shocks. The front end sat high and only had about 2.5" of up travel in front susp. In good air I was running 1.52 60ft 10.5 sec @ 128mph.

With that setup, the left side of car always sat about 3/4" lower than right side with no driver.

I added a glass hood over the winter and In an effort to lower and level front end , I have a 180lb spring on left side and 165 lb on right. That setup now has the left side only 1/4" lower than right no driver. Front end now has now about 3" of down travel and 4" up. The stance looks good for the strip , and sits well with my 160lb butt in the seat.

My concern is now on the street... with a driver and passenger, the front end sits too low and likely not safe with minimal squat available under hard braking, etc.

Maybe I just need to experiment, but would it be best to throw one of the 200lb springs on left side (leaving 165 on right), or should I get another 180lb for the right, even though car will now sit low on driver side by about 3/4" ?

At this level of racing , is it important to try keeping the front end level, or is it more important to keep equal rate springs in the car?

On side note, only street driving I do is around town, no long trips. Here is a pic of current stance no front shocks.

Thanks!

You should not have any references to “weight without driver” as all race setups are with weight of driver (ready to race with all fluids included).
I would suggest you find a 4-corner scale. On a drag car, you should have the same spring weight on the front corners.
You could have binding going on also.
I would suggest the book “Door Slammers: The Chassis Book" by Dave Morgan
