Just bought a sport MY00.

What size wheels can i upgrade to without having to do any work to suspension and arches.

Any good recommendations??

Cheers

I think the sport will be the same as the turbo models.

If that is the case you can go up to 18" or even some 19"s will fit:)
Though generally most stick to 17's as the tyres get more expensive and the ride quality suffers the bigger you go!

If you stick with 215 width tyres you shouldn't have any arch rubbing:)
