991.2 GT3RS - Tire Size on a 19" Wheel?
A while back, someone replied to a thread I started about 3RS tires for track events. They mentioned dropping down to a 19" wheel, but some replied that a 19 would have issues. Regardless, for any one running 19's on a .2 3RS, what are the tire sizes?

1. What is the aspect ration on these?
2. What the heck is a Fiat take off?
3. Where do you get them?

I prefer the narrower Fiat take off slicks cost and quality wise.

I think Trakcar is running Hoosier R7's as well - those look like Hoosier sizes. IIRC Pirelli (Fiat reference?) has the narrower slicks with more grip than the Hoosiers, but I've heard Porsche warns against using them as the suspension supposedly can't handle the g loads.

Thanks for tagging me
Yes, Ferrari challenge take offs. There are several vendors selling them. I bought 5 sets and all 5 lasted two days.
Much better then Hoosier, even used and they do t rotate on the wheel like R7 crap. I probably ran 6-8 set. The failure rate and the rotation on the wheel is frustrating.
Whatever the size is, it works fine with SC on.
I don’t know my Forgeline offset but new price is $7K plus TPS retail and selling for $3800 with TPS and a set of these Fiat tires that I set my PB the last time I used them so might as well.
Or call Autoquest and they can help you with a new shiny set with all info.
