I have a 68 Cvt with original 327/PG trans running 16x8 Vintage wheel Works wheels with 4.5 back spacing. They worked great until I installed a Right Stuff Detailing Disk Brake kit With 2" lowering spindles using stock springs. The shop that did the work assured me this was the proper way to lower the car.It moved the wheels out far enough that they now rub the outer fender lip on every dip in the road. Jegs site showed this kit should work on my car, but it clearly doesn't.
There isn't much room on the inside either; only about 3/4 " clearance from the tie rod. Any suggestions? If I was able to add some negative camber how much will it move the top of the tire inward? Is that even possible with stock control arms? Any help would be appreciated. Dave
Kit was actually bought from Summit (not Jegs), Right Stuff Detailing afxdc32dzx. Wheels are Vintage Wheel Works 16x8, 4.5" backspace using Firestone Wide Oval 225/50/16 tires.Maybe I should have used stock spindles and then cut the springs? I like the look with the drop spindles; the ride height is exactly what I was looking for, but the rubbing makes the car undrivable.I'm very disappointed and don't want to spend a fortune buying different size wheels/tires until I find one that will fit.Not sure what to do at this point.
I have had QA1 in all corners for about 10 years and been very happy with them in my -67 Camaro. I have the QA1 front pro coil system which is a bolt-on coil-over system. Back in the day when I ordered the front kit it only had two options for the conical springs, big block or small block (front weight).
Nowadays the front kit has 9 spring rate options and 4 shock options.
I have stock spindles and stock A-arms and have just lowered the ride height by turning the coil-over spring seat adjuster nut and setting the wheel alignment accordingly.
The only thing I've noticed about the QA1 coil-over system is that the springs settle for quite some time until the ride height doesn't drop anymore
I would say your choice is either coil-overs or spring spacers (ones that go under spring not in) to raise the front some for clearance which may be cheaper/easier than wheels/tire combo trial and error.
