alright this is what i got 15x7 10mm offset with a 205/50/15 falken azenis RT615 tires and the car is lowered some. i am not real sure as to what kind of alignment i want but i need something that will able to tuck some tire since the tires rub on the front. what i want is a good alignment for auto-x that i can drive on daily. i never have gotten a alignment for performance before and not sure what to get. can anyone offer some sugestions?
well i did some looking and i plan on getting -2 for camber in the front and rear with 0 toe IF i can tuck the tire with that if not i guess ill keep going - on the camber till they tuck...anyone got any sugestions on caster?
Where do the wheels/tires rub? Fender lip? Fender liner? You've got a pretty extreme wheel setup with an unknown suspension setup (I'm assuming KYB AGX and some lowering springs?????) so your options are more limited. If I were you I'd ask them to dial in 1.5 degrees camber up front, as much caster as possible (since there is a trade off between caster/camber you have to give up one to get more of the other), zero toe front. For the rear I'd ask for 2 degrees camber and 1/8 total toe in (1/16" per side). If you can't achieve those numbers because of your ride height or wheel fitment issues then I suggest rolling your fenders some more or changing your suspension to something with greater adjustment (either ride height adjustable coilovers or offset poly bushings.
I usually get at least 4 degrees caster but I'm only running a more conventional 1.5 degrees camber. I've seen as high as 6 degrees caster with only 1 degree of camber. More caster will make the steering wheel want to return to center but can make it feel heavier to turn.
i have tanabe sustec pro-ss coilovers. i have rolled all 4 fenders and the wheels rub on the fron under bumbs and hard turning. i had some 13x8 with zero offset with 205/60/13 tire and did not have any issues witht them but i have lifted my car since then.
also i check on the azenis they are wider then most 205's so that might be part of my issue
Give 2.5F, and 2.25R. Toe a little out in front for better turn in, and little in on the rear for my stability on exiting corners. Caster, depends, got p/s, then go above 4, don't, then go for 4. Alignment is a trial and error thing, gotta keep working at it. Think also about corner balance too, if you get even more serious.
FWD more rear camber
RWD more front camber
Has alot to do w. mid level cornering and accel'ng w. a limited contact patch.
Hardcore miata racers use -3.2F and -2.6R
At my alignment of -2.6/-2.1 I still wear out the outer edges of my tires front and rear.. although it's very even front and rear. Makes tire life better being able to swap L/R/F/R.
