Check the inside wheel clearance to the brake calipers too.

Suggestion
My only concern would be with a potential ABS issue due to changing the ratio of front to rear overall diameter but its only around 2.5% and probably will be fine.

It is currently running brand new road tyres on the stock wheels, which I fear will be worse for wear at the end of the day so was thinking about another set.

Good point, I'll put them on this weekend and do a little test run first, see if any issues arise.

My question is, do people see issues in running these wheels and tyres over the stock ones?

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.

In a couple of weeks I'll be taking the Spyder to a Burrows Day at SMP. It is currently running brand new road tyres on the stock wheels, which I fear will be worse for wear at the end of the day so was thinking about another set. As it happens I have a spare set of OZ wheels and tyres that are a little too big for the 964 (need guards rolled which I didn't want to do), that may just work on the Spyder. They are 18in whereas the Spyder standard wheel is 19in. I've run front and back wheels through the wheel fitment calculator and below are the results. Fronts look pretty close, but rear has a diameter difference of 25mm.
My question is, do people see issues in running these wheels and tyres over the stock ones? Appreciate any thoughts.
And here are the wheels in question on the 964.
The numbers indicate you aren't far off. Both cases the wheel is clear of the suspension and you're only 2mm closer to the rear wheel arch. Smaller diameter rear wheel will help clearance and improve acceleration-winner!
Time to get your hands dirty and fit the wheels. Check the inside wheel clearance to the brake calipers too. This is the only way to be sure.
My only concern would be with a potential ABS issue due to changing the ratio of front to rear overall diameter but its only around 2.5% and probably will be fine.
Yep, that's what I was thinking for the next set. Hmmm new tires, choices choices...
Good point, I'll put them on this weekend and do a little test run first, see if any issues arise.
Thanks for
the tips guys, appreciated!
