OK. That is kinda what it looked like to me when I read the Rules. Thanks for the help!

I can answer all those (and probably all your other) questions...

Your answer is no. Because your car is an '06, and there was no such thing as a 2006 Shelby GT, you can't convert your car. If you had an '07, and cloned one with all the right parts (and nothing you couldn't have gotten that's not otherwise legal to change under stock rules) then you'd be ok. But, as is you have to set your car up around the stock configuration. I've done setups for non SGT's as well, in fact I daily drive one and have it set for F-stock. It's close to as fast as an SGT on average, and on certain courses--faster (read slalom courses). There are differences in the setup to work around the different springs and bars on the two cars.

Yes.

"Yellows" are also known as Koni "Sport" dampers.

I am in the same situation, I have a completely stock 07 GT and was introduced to autox this year. I am on a very tight budget for mods, so I would like to get the biggest bang for my buck without sacrificing my Fstock status. I am also experiencing lots of wheel hop and hoping that there are some mods that can help with this without bumping me out of Fstock. Any suggestions would be appreciated.

Get adjustable shocks/struts and some good tires. I have Tokico D-Specs on my car and I love them. Everyone who rides in my car mentions how well it handles. I have only used them on one auto-x event, but they made a HUGE difference. Better tires might help your wheelhop problem and will probably make the second biggest difference in auto-x times.

Not sure if this would qualify as an autocross question but I want my '06 GT to hug the corners. What could I change to help keep it planted? Right now it feel lose. My old '65 2+2 seemed to hold better in the corners.

Stiffer sway bar? Lower the car an inch or so?

How are you defining "loose"? Are you doing anything with the throttle (or brakes) while turning?

What do you have for wheels (sizes) and tires (sizes and models), and what inflation pressure(s) are you running?

How many miles on the car?


My first "parts" thoughts involve shocks/struts. The S197 is several hundred lbs heavier than the '66, so the "feel" won't be quite the same even at the same cornering speeds on the same roads.

It feels as if the rear wants to slide. If I give it anything more than a little throttle, it spins out. Not as bad as if I were on ice, but it definitely breaks lose.

It is a stock '06 GT. The P.O. only added the stick on quarter window covers. I have only added miles.

It has about 58,000 miles

I realize the car is heavier and packs a better punch. I'd like for it to corner like its on rails through.

I was thinking of replacing the springs to drop the car an inch or so, maybe adding a stiffer rear sway bar, followed by some better shocks.

The goal is to set it up to enjoy the curvey roads in the North Carolina country side.

Thanks for any info, Norm.

Shocks/struts for sure. But not a stiffer rear sta-bar if you're already "loose" for the way you drive (it'll only make it even looser).

A little practice getting smoother "throttle modulation" is probably in order. Think in terms of "squeezing" into the throttle rather than snapping it open. As you pass the apex and start unwinding the steering you gradually add in throttle.

Maybe Sam Strano will add a thought or two.
