I'm sure John has some very technical things in mind when he asks a question. Jt is very detail oriented and it shws on the track and in his car preparation.
I'll give you my scattered less detail oriented thoughts. I've ran the yellow Z numerous times, mostly on victor racers. 245 17s rear and 225 17s front. Spring rates from 225 to 350 at varoius times. Struts are double adjustable konies. No matter the alinment settings, springs or shock adjustments, I steer with the throttle. Turn in is crisp and predictable. The car will rotate how and whenI want it to based on throttle input. I love it but I want more grip.
My yet to be proved solution for this is 315 17 rears and 285 fronts. Different shocks and springs. Lighter car with a little less camber in the rear and more caster in the front with a little less toe out in the front.
My goal is to have a car with similar handeling characterists but at a higher limit. I*'ll start the process of debugging the car soon.
The general alingment specs on both cars follow John COffeys recomendations that is in a sticky somewhere.
I did end up geting the big tire car about a half an inch lower at the rockers than the yellow car. I've yet to scale the car but I bet weight distribution will be very similar between the two.
If I rambel or am incoherent it's 10 mg of valium speaking:biggrin:
John, What are you working on?
