I just bought another set of wheels last week to mill out the rears and run a non-staggered 245 setup.

I'll let y'all know what I think in a couple months. I probably won't get back out to the track until that 3-day Buttonwillow event at the end of Sep.

Edit: BTW, I'm running stock '00 sway bars f/r, JRZ triples, 750 lb/in front, 700 lb/in rear. Considering going to a higher rate up front, but I will see how well this balances out first.

Do you have the v1 or v2 Comptech front bar? It looks broken to me...

I dont think youd be getting much understeer with a broken front bar. I really dont think this is the case.

just alot of body roll in a decreasing radius descending elevation turn

heres my body roll in the same turn with almost an identical setup to gfactors (car wise)...

he was a little further along and more to the outside of the corner (where you are supposed to be)

this is also the major understeer turn. You can see it might just be the environment and not the car or driver.

Perhaps the front roll stiffness is too soft allowing the the car roll over on the outside front. I though I read something like that in one of the Carol Smith books.

I took the Comptech bar out today and put the 02 OEM bar back in (which only had about 2000 miles on it/

The Comptech looks ok, bit there is just a small bit of play in it (inner bar)

I am going to try the OEM front bar and no rear bar, next time out.

You might wana bring the comptech and rear bar to summit just in case you change your mind.




sounds like the recipe for an instant race car (be careful!)

Sounds like you are happy with the characteristic of the car at high speeds but could use more front end grip on tight radius turns? Then you need more caster! Additional caster is possible with the SPC instaled diagonally. Keep you current static camber settings and add +2 or 3 deg of caster over factory settings and you will notice a big difference negotiating those tight turns.

Something to try, now won't that make the steering effort harder?
