Got a track related question? I'll try to answer.

Would 225/45/17 be that bad for track use?

225/45/17 will be a stretched tire on a 9" wide rim. The proper size is a 235-275 width tire.

245 will work great, but you'll lose some straightline speed in exchange for that increased cornering grip.

I'm of the opinion that only the PVC side is necessary. That may change with further testing

Absolutely, but not in a good way. You lose grip as tires heat cycle out.

So does this only help R-compound, or is it just clever marketing?

I would like to stay between $2000-3000 for aero. My total budget is $5000 to invest on the car for track proposes. My FRS is going to my daily driver and my track car, with that said, I care more about having functional downforce than stuff that just looks good.
Thank you!!

heat cycling r-comp tires to prep for a single race is one thing.

heat cycling street tires for autocross is generally futile, unless you're willing to have a single set of tires for that magical run at the nationals.. because otherwise "each run" is a heatcycle, so you would break 5 at your first event already.

It's for select R-comps being used for select events. It's not for everyone. It's cliche, but if you need to ask about it, you probably don't need it.

I'd recommend a good custom splitter by a local shop of your choice, and a Voltex wing. If you want to use just a lip, we've found the APR lips to be the most functional of the "off the shelf" lips.

I've seen two APRs, do you find them both functional? I want functionality, but also a relatively stock, or clean appearance.

Yes, they're functional. The splitter is not as pretty, but more functional than the lip.

Considering I'm still at the point where the biggest mod I can make is to my ability, I suppose the clean version would be just fine. LoL
