So now that I have some of the running issues sorted out with my car, it is time to get a few things addressed with the suspension/steering. The car as it currently sits definitely has suspension issues. I did put new dampers on about 2 years ago (car sat for the last year and a half). but I'm pretty sure the springs are shot. The car still squats in the back with new rear dampers and the right front is slightly lower than the left front. I also have very bad dive and nose lift when accelerating or braking. Add in that I have what I believe is massive bump-steer on acceleration, means the car is fairly twitchy and quite a handful at anything over 1/2 throttle. (Keep in mind, I do have an OBX LSD in the car that was in good working order when I pulled the drivetrain out of Lucy 1.0 to put into Lucy 2.0. This also included swapping the 5-speed K-frame over).
The torquesteer/funnybusiness in the front is what usually gives me the most grief. When I get on the throttle, you can visibly see the front end rise by at least an inch to 3" (at WOT) or more (caveat: guestimate). This causes the steering wheel to rotate to the left by about 1/16 to 1/8 of a turn. The car then likes to start pulling to one side or the other under heavy acceleration and proceeds to bounce from pulling to one side then the other. Couple that with the random steering wheel movement makes keeping the car in a straight line very hard as when you let off the throttle and the front end comes back down, you are now oversteering to one direction or the other. While I do have an LSD (I will try and check to make sure the LSD hasn't separated on me again causing all sorts of wierdness before), I believe this erratic behavior is triggered by a completely unbalanced suspension setup.
I believe that the first order of business is to deal with the rear springs as I am only an inch or two off the bumpstops at present. This also gives the car a very noticeable rearward rake angle of approximately 1.77 degrees. Couple that with the extensive compression of the springs, I believe I am genning excessive rear squat and front end rise. This (from what little I know about suspension) can cause all sorts of issues with front end alignment, bump steer etc.
wheel arch heights (ground to wheel arch through center axis of wheel)
LF - ~27.5" (Spring compressed to ~8.25")
RF - ~27" (spring compressed to ~8.75")
LR - ~25.25" (spring currently compressed to 6.5")
RR - ~25.25" (spring currently compressed to 6.5")
I have found some 10" tall, 5" round springs I believe will work with no to little modification and can be had in many spring rates from Speedway. I am considering going with a linear rate of 350lb/in. This should get my static height closer to normal and increase my front anti-lift/rear anti-squat. I believe this will help bias the weight distribution back towards the front of the car and may alleviate some of the torquesteer/funnybusiness going on in the front end.
If anyone has input on spring rates for a good balanced setup on a P-body, I am all ears. The same goes for finding what is causing the erratic front steer issues under acceleration.
