Spiller, what tyre size are you running on the 996 gt3 ?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I've got a set of Alleggerita on my 7.1 GT3, I seem to recall that the rear track is a little different, but I think the specs should suit. Can someone confirm?
Hey Vinnie,
I have Spiller's old OZ wheels, so I was reaching out to him to see if he did recall the specs. Unfortunately I've got my car put away and I won't get to it for nearly a month.
@Robert930
does have exactly the same wheel, maybe he can help you.
Hi Vinnie they're 295/30/18 on the rear and 235/40/18 on the front. Wheel widths are 18x11 and 18x8.5
I have run as wide as 315/30 and 245/40 on the same width wheels FWIW.
997.1 S run 295/30/19 on the rear = 659.6mm overall diameter
If you put 295/30/18, the overall diameter will be 634.2mm. The difference in 25.4mm less. I think that might be a bit much and speedo will be out.
However if you run 295/35/18, the overall diameter will be 663.7mm. Thus the difference will only be 4.1mm more.
they are definitely smaller rolling diameter, so much so on my 7.1 I'm riding the limiter into the T1 brake zone at smp. I don't have that problem running 19's..
also if you have TPMS fitted, you're going to have error come up every time you start the car.
Just some thoughts!
If you you don't need them in 18" for runnning R Specs, they definitely do them in 19" in the right offsets and widths.
