DE Alignment, 5 bolt alignment Options

[Bill Kohnke]

OK I have the 5 bolt conversion done, she is a also a 6 cyl. now. What alignment recommendations are out there for track use? 205/50 x15x 7"wheels on front, 225x50x15 x8" wheels on back with DOT Yokohama Advan tires.
Watkins Glen - Black run group and I will be running her hard.
I can get up to 2 degrees of negative camber, maybe a little more. Caster looks to be about 5 1/2 positive. I was guessing that 1/8" total positive toe may be what I'd want.

My car is set up for AX and not DE and there are important differences. But there are also similarities of good handling characteristics. Incidently I run the same size wheels/tires as you.

Your tire selection may in part go a long way in determining camber settings. While one tire may respond well to -3 degrees negative camber, another may tolerate no more than -1.

I run 1.3 front and 1.7 rear. I run KUMHO 710s that work well with less camber.

I am not familiar with your tire, but hopefully someone here will be and can provide you some insight on camber preferences for that brand. Or, you may read up on what the tire manufacturer recommends for camber, tire temps, and base air pressure.

On my car, we took the side that allowed the least amount of caster and balanced the other side with it, which was 7 degrees caster. Which gives me maximum straight line stability (which helps to combat my toe-out instability).

I tend to favor lower toe-out settings since more toe-out creates more scrub which reduces speed, increases tire wear and produces more bumpsteer. And for the higher speeds you will be going, there will be more straight line instability. And for what purpose? Faster turn-in? I'm not convinced our cars have a problem with turn-in. Mine is set at 1/16th.

It sounds like you may not have done an alignment yet. If so, have it corner balanced first and then the alignment. Even if you don't have rear adjustable coil overs, you can still corner balance it to some degree. It can be a big improvement.

You didn't mention front swaybar, but I assume you have one.

For me, none of the figures you've stated seem way out of the norm and anyway, they're just a base from which to start your dark journey into the black art of suspension tuning.
