FYI - one full turn on the tie rod equates to 3mm toe change on the side you adjust. You could get the alignment set to zero for street, and put in a half turn out on both sides for events, then turn it back before going home.
@Yri What I meant by coilovers for camber gain is if I lowered the front lets say 1inch it might gain me another -0.5-1 degree due to double wishbone geometry. (I don't know the exact numbers I just searched alignments for guys lowered about that much) After corner balance I'm not sure where it would end up though.
@Lobuxracer we run the same rules as SCCA solo. So I run in STU which allows 1 control arm to be changed or modified . I have the RR USRS rear LCA bushing (bearings not allowed in STU) and super pro bushings everywhere else on the car except for the 2 bushings on the rear knuckle. I also just started running time attack but classing for that is based off of modification points. I think I'll give the front toe out a try but toe out in 0.5mm increments. 3mm front toe out might kill tires on the street because I do still drive the car on weekends and to motorsport events.
As much as I'd like to get the figs UCA I don't think the open rod end will have a long service life if being driven on the street as well.
When the SPC adjustable ball joint slips what does it do go max negative? If max negative adds -1.5 that would theoretically put me at -2.9 or do you not want to run that ball joint on max negative?
Yes, lowering a car will add more camber, but it isn't truly adjustable side-to-side. Also, realistically speaking, running an adjustable ball joint throughout its entire range should be safe, but depending on the build quality, that may or may not be true (SPC ball joints don't seem so bad). As Lobux said, adjusting toe isn't an issue if you want to go from street to track.
