Your experience is requested - Autocross / Track Setup

[DemonWorks]

Hoping to get some peace of mind that I chose the right path. The car is a 24 GT with Performance package and regular suspension. I want to run gt500 Wheels on the street (20x11 305/30/20 and 315/30/20) and the "track wheels" are Apex 19x11 / 19x11.5 305/30/19 .

Parts to be installed:
Ford Performance Springs
Steeda Camber Plates
Koni Adjustable Shocks
Steeda Rear Shock mounts
Steeda Sway Bars
Steeda Stop The Hop Kit

I am about to install everything then maximize camber for track use. Guidance on specs would be nice, if you have experience (leaning towards autocross setup) I'm a GM tech and had a few camaro's prior and I was just going to set this up to similar specs. Likely -2.7 or so up front with zero front toe, maybe a smidge toe out and -1.5 rear .32 total toe in rear.

The question, will I be running into rubbing issues with the GT500 wheels/tires when on the street? I am pretty sure the track wheel/tire setup will be just fine, but that's an assumption based on research. I appreciate the responses !

If you look on Apex’s website they have a pretty comprehensive fitment guide. I’d start there. Steeda also has a really good video on S650 fitment specifically. Can’t offer any first hand experience.

i run 19x11" front and 19x12" rear wheels, front rubbing is minimal and rear rubbing is an issue at fully compressed suspension. i've also done autocross and with the factory alignment, i am only 1 to 3 seconds slower than Porsche 911 GT3RSes

are you lowered or stock height?

Thanks ! Good info there.

stock, i cant justify going lower. but i also have a dark horse with the handling package

ah! I wonder if the Ford performance track springs are comparable to the springs that come in the Dark Horse Handling pack? regardless, I appreciate your input!

Can you do me a favor and take a measurement from the bottom lip of your wheel to the lip of your fender opening, please?

1 to 3 seconds? Thats like 10 seconds a lap on a road course. Autocross is usually decided by tenths.

Also, I can't comment on wheel clearance but that much camber will eat up tires in 2 to 3 thousand miles or so.

Not in my experience, The toe is what eats tires, camber is ok.

My 3 years of autocrossing an SRT4 with -2.6 front camber says otherwise. What is the stock spec for Mustang front camber?

Really proud of you. I would like to go back to the original conversation if we could.

the original conversation was you saying you were going to run -2.7 front camber. I just commented on what that will do long term on the street. good luck with your setup. It doesn't sound like you want or need any tips, or know the answer to my question.

I'm looking for input on a track setup from people with mustang experience. You came in here trying to discredit Roket's input then went to your opinion of street wear because you drove a neon with negative camber. I told you that toe wears tires and camber is ok. Yes, excessive camber will cause added tire wear but not to your 2-3000 mile claim. You ignored the toe comment and that makes me feel like you don't understand how it all works together. I stated in the initial post, I was looking into zero front toe. Granted, there is a chance you wore your tires excessively on the neon because the alignment didn't have the toe correct, but that's all assumptions. Maybe you ran aggressive front toe out and wore your tires that way, maybe it was influenced by the excessive power and torque steer.... either way, has nothing to do with what i asked. Then you asked what the stock spec was which again, irrelevant, and it told me you didn't have the experience I was looking for. The stock camber is roughly -1 and is not adjustable in factory form.
