GT3DE

I have a fantastic setup that I like on my 2011 GT3RS -- for Hoosier R6.
But the reason I got this RS is to run similar cars with GT3 DE Cup. The GT3 DE Cup spec tire is the RA1. What I have heard so far is that the sidewall is stiffer on the RA1 than the R6 so the RA1 requires less camber in the setup than the R6. I am currently setup for R6 with camber at 2.75 front and 1.75 rear. What should I change this to for the RA1?

Just copy the above and you are good

Clarke, IMO leave your alignment settings as is, and use a probe pyrometer to compare R6 and RA1. I have a feeling, as Randy suggests above, that you will end up leaving things unchanged...

Goldcrest setup Grady's car for R6's. Find out where they set his at

Yup, I have the same as Randy, very similar to what you have now. leave it.

So, is the RS1 the official DE Cup tire now?

It's been that way a while now

We don't need $500.00 slicks..

nice !!!

Finally a decent and long lasting tire for the DE Cup. Same price a Hoosier R6.

I wonder if they last 16HC or more to match the RA1 longevity.

Which tires is that?

Thanks Toyo!! Because another slick tire is exactly what we need in this segment.....

Don't get your panties in a wad. . It is the same compound as the R888 as per Toyo's website. So it may not have grooves but it sure isn't an R6 much less a Michelin/Yokohama/Dunlop slick. Cory Friedman tested them at RR and was not impressed with their handling or lap times.

so it may last and not heat cycle out as fast
