Scaling of the car?

[1990whiteg60]

I am going to scale the car this weekend, 84 GTi ITB, and I was wondering what some of the numbers that others where able to get. I am looking for your cross, rear, left and right percentages if possible. Thanks again. Shawn

Shawn,

I'd have to pull out the book on my old car (ITB A1 GTI), but I used to try and get 50% cross-weight.

Try for 51-52% LR->FR cross weight. Seems like a tiny difference but you should see a real difference in lap times on a clockwise track. Obviously reverse for the lefties. You won't feel it, but you'll see it on the watch.

thanks guys, what would you suggest for a front to rear percentage?

You will get whatever F/R split you get - you can't alter that to any measurable degree with spring perches. You'd have to move components or add ballast to affect any change here...

I'm also interested to hear Bill talk about asymmetrical setups. We used them on the Renaults to pretty good effect but they tend not to come up in conversation in the IT crowd.

The "just set 'em and forget 'em" crowd runs mid pack http://Forum.ImprovedTouring.com/it/smile.gif

You should see what guys do at the LimeRock R-oval.

Bill-your abreviations confuse me. Are you saying RF+LR =1.02(LF+RR)?
what would be your setup for slimerock?
what would be a modest rear toe setting there (with spherical brgs); agressive? What other pearls of wisdom would you have for an old fart? Phil

We consistently run asymmetrical setups, even to the point of weight jacking between sessions to affect the handling for current conditions...I thought that was the norm...?

Well, every time I post something about wedge in a strand about corner-weighting, people make polite noises about how road racers "don't do that."

in my sidepocket are 2 "U" shape alum shims that drop into rear spring pockets with corner jacked.

>>Are you saying RF+LR

yes that's what I meant sorry for the typo.

Phil, you're too smart to be asking questions like that http://Forum.ImprovedTouring.com/it/biggrin.gif

re: LRP... others here are much more qualified and experienced there than I.
