Gotcha.

up last season to take the push out of the car.
Ok. Now that you lowered the front end 1/2" you're loading the front end a LOT more, and it has gripped up the front ... making the car loose with the high RC. If you're not clear, dropping the front end 1/2" is a HUGE change.

With race cars, raising or lowering either end of the car 1/8" is a significant tuning change. 1/4" is a major change. 1/2" is a ton. It will affect the car's grip balance enormously. We don't do this a lot in the front of stock cars, because we're usually at or near the minimum already. So if we need a significant change, we might raise the rear & reset all the link angles.

It slips my mind ... that because you don't have any class rules ... you can do whatever physically works. Dropping the front end 1/2" is where you got the majority of the added front tire grip. The caster & camber changes you made played a smaller role.


I am now at a point where I'm getting more front grip so I am able to drop rear roll center to increase rear grip.
Yup.Yup.

I'll double check on how much each bolt location moves roll center but my guess is about an inch.
Ok. For discussion sake, post the max & minimum height from the ground ... and the difference from hole to hole.

Skatey would be a decent description of how the front feels now.
Is "now" session #5?
At what part of the corner does the front feel skatey?
Does the rear now have "good grip" throughout the corner?


I'm thinking it's a combination of still a bit too much castor that might be affecting my scrub radius

What is your scrub radius & Caster at currently?

and I dont think the toe is the same as when I left the alignment shop
Hmmm. Curbs?

not to mention it would help to have a decent set of shocks.
Of course.

I'm going to verify if the alignment moved any next Saturday.

Cool. Get your scrub radius # & caster degree then too.
