Extended ball joints..
 

..after lowering to correct roll center. Yay or nay?

I would live to be able to try these. Seem to work well on a lot of other cars so should work on the 86.

Hmmm, I guess suspension geometry with regards to these ball joints is not a hot topic these days? :)

There's a few companies making front LCA's with roll center adjustment built in...

I think that the handling is so good factory that ppl havent felt the need to correct it with these parts. I am keen to.

we have been doing this for the last 8 months and the sig records the results

Stock arms modified allows 3"+ drop to be corrected with included bump steer correction tierod ends.

or our full race arms (increase in NVH as all bearings are now metal).
These are track, camber, castor, roll center, and antidive adjustable.

depends wether you care about lap times or looks.

if you're out to maximize the performance of your car, then the answer is a most definite yes.
