997 Turbo wheels on 987

[anthonyp0808]

I am considering the following on Fleabay on Australia - 987 Turbo wheels (not Porsche branded but previously fitted to a 996 wide body)

Front wheels are 19 x 8.5 with 57 offset

Rear wheels are 19 x 11 with 51 offset

Front tyres are 235/35/19 Continental Sport Contact

Rear tyres are 295/30/19 Continental Sport Contact

I understand sizes and profile but not offset - what is this and how does it affect fitting to a 2007 987?

Best to look at aftermarket tuners like techart and 9ff etc. They offer wheel and tyre packages using tyres up to the size used on the turbo wheels you are looking at. I think the 997 turbo uses 305 rear tyres though.... . The 987 turbo look wheels should be using 265 tyres. You will need to work out the best spacer and understand offsets to confirm that the turbo wheels will fit. Techart have their wheels made with a particular offset then fit spacers to ensure the suspension clears the inside of the wheel and the wheel does not extend beyond the arch. take a look at tyrebibles.com for explanations of wheel offset and diameter and rolling radius compatability.
