Thread: Preparing a Street(turbo) Car for a Road Course?

On the AGX's it depends what springs you have. When I ran them with 350F 300R springs I preferred 2 front. 4-5 rear.

I never used the softest setting even on Eibach sport line springs and AGX's.

You want enough damping to control the spring and at a higher sprig rate than stock the softest settings do not provide that.

Very Good point wes!!

And for point of reference, he is on Road magnets, so what are those rates?? 250 or so for fronts and circa 180-210 for the rear??

The main point to take away is set the car and LEAVE IT ALONE.

Now I'm confused! lol..

RM springs are:

325 front
290 Rear

To add to this, at the same time, you don't need an extra bunch of damping to control the lack of spring like a stock setup. So no need for 4/8 or something like that.

I would start at 2/4 similar pressures all around. And juust drive the car and not touch it as Nathan suggested. Too many people start messing with a million settings before they even have adequate seat time to notice the differences.

Fix the loose nut behind the wheel before you start fixing other things...

OK, 2/4, I can do that. That's close to what I run on the street so it shouldn't feel too different.

Regarding tire pressure. I did some reading and found that tire pressures are mainly to be set according to tire wear. You want to make sure that you have even wear AND also that the tire doesn't bend too much to actually go under the wheel(handling of course is also a reason..but probably one I won't be able to adjust for at my experience level). I can understand why you want a higher pressure, but so close the max tire pressure I'm not really getting and here's why...the reading I did said that tires can inflate upwards of 10psi from cold pressure depending on how hard you use the tire and the ambient outside temperature(it'll be HOT July 11th). If I fill the tire pressure within 2-4 psi of the max sidewall rating and the tire goes from let's say 40psi to 50psi..and the sidewall pressure says 44, how would that affect the tire? I'm worried of it blowing out or something on the track. What am I missing here??

Don't inflate to max. Inflate to recommended.

Don't worry about it after that for first day. Later you will want to do it based on tire temp, but can see based on wear also.

recommended as in 33F/30R or whatever is on the inside of the door?

How hot is it going to be on the 11th? Stick with recommended tire pressures for now. Keep it simple.
