305 Super Sports on Carrera S

[pdavis1]

Just picked up my car after having new Michelin Pilot Super Sport tires installed. It's an 06 Carrera S cab with the factory sport design wheels. I went with 305's on the rear since the back tires always looked too narrow for the rims. I had also previously installed 5 mm spacers and it still looked to narrow. The new rears look awesome, pretty much flush with the outside of the fender. Heading to Road America next week for a DE event, worried about cutting the tires. Does anyone understand the geometry of the arc when the suspension compresses? Will they tuck in? Should I remove the spacers?

If you're at stock ride height, you should be fine. The suspension travel should limit the tire from rubbing at the lip. The spacers may affect the handling, but the tire width is the same as I have on my C2S in the rear and I don't notice a significant difference. You may have uneven tire wear issues with the spacers unless you've had an alignment with them on.

If you are running the factory 11" wheels with the 5mm spacer and the 305/30 tires, you should have no rubbing whatsover. Enjoy that track time!!

I have 325 on the rear and the 5mm spacers

and they don't rub.

Car is at factory ride height with Sport Chrono package. I'll give it a try next weekend and see how it goes. Paulspeed, installed the GT3 rear bar you suggested, anxious to see how it handles, will let you know.

Got back from Road America, no rubbing at all. Tires are awesome, I guess I didn't push it hard enough because I didn't hear any squeeling from the new tires. Definately would recommend the new super sports.

I also ram at Road America May 6 & 7 for the PCA Milwauke DE.

Was a good time and tires grabbed well.
