was looking a sexy ssr's profs last night, 9j +3 ?? was in two minds weather id take a punt and get em and hope theyd fit. tough game this wheel fitment malarky.
I'm running 17" 9j +22, so that would be 19mm more than mine, which is quiet close to the rolled arch with a 225 tyre. I'm running -1 degree on the back, so quite sensible.
If you run them with a 215, that would be an extra 5mm of clearance straight off, and a couple degrees more camber would tuck them in.
It doesnt matter if the rear wheel hang out the back a bit, as it tucks in under compression. To check if it's going to catch, I disconnected the lower mount of the damper, and jacked up the lower arm to swing the suspension through it's travel until it was next to the arch
Edit: 9j +3 outer face will sit in the same position as the outer face as Al's 10j +16. They might be a bit harder to fit though as the tyres wont be stretched as much, thus less clearance, due to the 1" narrower rim., Although i suppose the strech of a 215 on a 9j would be similar to a 235 on a 10j
