Hey fellas, I need a quick ITR AutoX setup for a starting point.
tires are dunlop fm901s in the front, and avs1000 in the rear. (im poor)

Stock Itr with Koni yellow Shocks.

how should I set the tires?Psi? front rear?

How should i set the shocks.

any info is an asset. thanks in adv.

 

i would run full stiff in the rear and full soft in the front for starters if you feel the car is diving to much crank the front up a bit. defnetly wanna run stiffer in rear by a good amount.

as far as tire pressure goes take some chalk with you. chalk you side walls to see how your tires are rolling over. i usually start the day with 45rear 38 front psi and adjust from there. temp of the day will have big effects on this.

do what i do. find a more experience driver with a similar vehicle and see whats working for him that day or what he might recomend from how your vehicle feels.

 

Thank you for your reply.

Ill do just that.

 

Just a quick note: Adjusting the fronts wont affect dive at all, and will reduce on power transient grip. My recommendation is to leave the fronts full soft.

 

Good advice so far. I think those are good starting points: rear shocks full stiff, front shocks full soft. Last time I ran street tires, I was around 42 psi front. The basic trick is to set the pressures to get all the grip you can in the front (check for rollover), and adjust the rear pressure to reduce grip there based on how much oversteer you want.

 

Throw out any advice you received. You have a complete oddball setup, and unless someone has driven a car with the same setup you have, it is a complete shot in the dark that any of the suggestions will work for you.

Because of the different brand and compound tires front and rear, you need to start out with a setup that isn't biased in any particular direction. Since it sounds like you're somewhat of a n00b, my recommendation is this.

1) Set all four shocks 1/2 to 3/4's stiff, same front and rear.
2) Inflate your tires roughly 10psi higher then your run on the street (low 40's all around)
3) Drive the effin car!

Until you are comfortable with number 3, don't change a damn thing. Ideally, you should be getting on matching tires at all four corners so you can address driving and setup issues directly instead of band aid around a funky tire combination. My guess, knowing what I do about the tires in question, you'll find the thing evil loose pretty much everywhere on course.
