Competition / Track Tyres

good point Ryan!
Forgot all about that. So long as you don't have narrow guards, we found out the hard way, or at least Marcus did, they are the wrong offset, you need to roll the guards. If you have wider rear guards you can put them on.
Marcus only bought the 6 inch ones though, so I don't know what the offset is on the 8 inch ones. The wheeels are of a high quality, but they will probably require longer wheels studs than you have, and the wheel nuts are a different shampher (spelling) to the Porsche nuts. However they looks awesome! You can get the UK Minilites, which are more expensive, however they have the correct offset and shampher.
There ya go!

Minilights aren't my cup of tea at all, I'll stick with fuchs.

I though I'd give Stuckey's a call and find out their recommendations
They came back with:
front 205/55 d01j sps compound
rear 225/50 d01j s compound
Running 28psi cold

Any comments on this configuration?

That was the initial recommendation I received. Was advised against mixing the profiles so ended up with DZ02G's on the front.

No issues running the 225/50 on a 7" wheel?
Do you have standard guards or flares?
Did your RPMs at 100km/h change at all?

225 will run fine on a 7 inch rim.
You won't nice it that much at 100 kmh. It changes it slightly.
To fit 7's under the guards, you will need to check the offset of the fuchs as they differ depending on part number.

here's a handy link to help you determine changes in rpm for diff't tires

Looks like 3150RPM with this tyre package for 100KM/H
