I found the answer, lots of threads to read. Presuming the 360 Starfish hasn't been machined before, it should be using 52mm bolts. 7mm shave = 45mm bolts 12mm shave = 40mm bolts 17mm shave = 35mm bolts I found a set of Titanium bolts on Kijiji, Montreal, asking $250 CAN ($195 USD) Used, quantity 20x I phoned them up, fellow said it's a 52mm shank.
I find this really really hard to believe assuming you had factory diameter tires and the car wasn’t lowered.
I had standard wheels, tyres and ride height. Driving out of my condo, I have to go over a speed bump while turning rather sharp left. The left wheel goes over the bump first and, even though I went very slowly, that was when it rubbed (happened twice although I tried to change the angle at which I was "attacking" the bump). Before, and after I removed, the 15 mm spacers, I had no problem going over the same bump in exactly the same way. Another member's car with 15 mm spacers at front: Image Unavailable, Please Login
Something unusual is at play here. I know of many 348 with similar or more aggressive offsets in the front, including mine.

This car, and others like it, have an 8.5 et36 front wheel (the equivalent of the factory 7.5 on a 26mm! spacer)and, iirc, 355 spec tires.

Tires are 235/40-18 Image Unavailable, Please Login
