Regarding the ride height, are you going for optimum performance or compromising on looks?

Lowering a car, all else equal, will often INCREASE roll.

That's why I minimized my "drop".
My drop is probably about 3/4 to 1 inch in the front.
I'd like more roll actually... the TEIN springs are very stiff, and I don't think it allows enough roll to really load up the outside tires and take advantage of the negative camber I have set up.

The front springs are 392 lbs/in, and rears are 671 lbs/in. I may opt to swap the springs out for ones from their "EuroDamper" setup, with 280 lbs/in front and 392 lbs/in rear. They recommend I get the shocks revalved though, rather than just using the softer shock settings.

Wow that is a massive differential between front and rear.

What's your camber setting? On track, I run about -3.5 and my 400fr/500rear springs are just perfect, imo.

Really? Shouldn't be too tall. Unless you're slammed or something. But a good amount of camber should resolve any issues.

Dunno how tall Toyos run though, so I have no clue.

That sounds about right for spring rates. I'm not sure what my camber angle is at the max setting I run. I'll have to measure it. I'm thinking slightly softer than 400/500 spring rates are best for the autocross courses, to allow more loading to the outside tires.

I want to start hitting the big tracks soon... ...

but I worry about overheating with my 6AT...
