I am having a problem in which driving at highway speeds the car wants to dart to the left or right and I have also heard the term “nervous” being used which I think applies to my situation. The car is a 1989 944s2 and I spent 6 years doing a total restoration on it and making performance or reliability upgrades as warranted. The car has been in the alignment shop several times in hopes that the issue will be resolved, but it still remains.
Apparently TSB 49303 explains that going from a 16” wheel to a 17” wheel requires a different caster setting. However, I am running 18” wheels and is commonly done on the late 944’s.
What I am hoping for is someone who can analyze my latest alignment report or if someone can spot an obvious problem with the configuration. The shop that has been doing the alignments on this car are the only shop in town that specializes in high end European cars. I feel that the problem resides within the alignment settings since every moving part the front end is brand new and I will list the parts below to help with the analysis.
Wheels: SSR GT10, Front 18x9, Rear 18x10
Racers edge camber plates, mono-ball
Elephant racing “sport” caster blocks
Rebuilt steering gear with about 100k miles on the pinion gear
New steering shaft and u-joints
Racers edge billet A-arms
New tie-rods
Koni inserts with adjustable height
Thanks in advance
