Hey folks, anyone here happen to run 265/305 Supercar 3R tires on 19" (Apex SM10) wheels on the 718 GT4?
It's supposed to fit well with an aggressive alignment. I have them on my car with -3/-2.5 front/rear camber and 9 degree caster and they rub quite a bit at track speeds (required camber plates and toe links to get this alignment).
I'm curious if anyone is running these without rubbing and if so what you had to do to get them there.

 

That's odd. I ran those at the tail end of the season (on a set a Titan-7 wheels, though) and didn't have any issues with rubbing. I did have some rubbing on the rear inner fender wells with Nankang AR-1s on SM-10s. My settings aren't even as aggressive as yours: front camber is -2.7 with zero toe, rear camber is -2.2 with 4.4 total toe. I'm running the stock ride height, though; did you drop your car a bit?

 

Yeah dropped the car by 8mm. But I thought that shouldn't matter since height at full compression (when the rubbing happens) is the same?

 

do you have the specs with offsets on the Titan7 wheels? The SM10s are 19x9 ET50 and 19x11 ET46 I believe.

 

F: 19x9 5x130 +48 / R: 19x11 5x130 +52

 

I am also interested in trying out these tires on my 991.1 911 GTS. Should I be concerned that the tires are not XL rated? The 911 is not a DD and participate in Auto-x and DE. Thanks.
