I am trying to fit slicks on a 2008 Cayman S and cannot find any slicks that will pair with the existing 18" wheels. What are my options? Do I need to change to a 17" wheel?

 

I haven't heard anyone do it, but just a word of caution:
The Cayman S is not equipped with a dry sump. Running on slicks, you will pull G-forces that will give you an issue with lubrication and possibly an engine failure.

 

If only I would get off my can and create a custom dry sump. I should for the few of us who want to do such bad things to this brilliant car.

 

so hoosier R6's would be a bad idea I guess? 09+ ok ?

 

ill let you know on the hoosiers.. eventually ill have a pair this year..
but im in 12 CR.. dont think oil sump is a probelm..
but then again let hope the turbo doesnt present any probelms either.. not that it should..

 

... Most...?

 

Nitto NT-01s
BF Goodrich G-Force R1s
Hooser R6
These have 18" tires to fit a Cayman

I run the BF Gs with 225-40/18 and 275-35/18

 

Are you guys using the term "slicks" for D.O.T. R-compound tires?

As for R-comps I just put a set of Nitto NT-01 18s on my car and it make all the difference in the world in handling and braking. I was not having much fun on the Michelins.

 

I could be wrong, but aren't Cayman racers running slicks? And, no, I'm not talking about R comps. Plenty of people running Hoosier R6s.

 

I'm pretty sure the Interseries Caymans run Hoosers. 245/295

 

You have that big engine, you need some tires.

Will you take me for a ride next time you're at Barber's?

 

Id love Hoosiers but scared about my 2011 spyder not being "dry sump".. Says in the manual not to use racing tires

 

"You have that big engine, you need some tires."

Also GT3 front brakes w/ Performance Friction 08s - Michelins could not handle the braking power. And the PSM didn't like locking them up.

"Will you take me for a ride next time you're at Barber's?"

If they'll let me. Road Atlanta in 3 weeks. Do I know you, Dave?

 

I don't think we have met yet, I drive a Grey Boxster with 987S Barber's tag. I'm an instructor for the AL PCA, so I can ride with anyone.
I'll be back out at Barber's next month with ReZoom.

 

For 2012 Cayman Interseries is using Pirelli slicks. Way stickier than R6's.
