Rotas fitted perfectly, (5x100, 9.5 et38) 15mm spacer at front and 20mm at back. For those who want to know, the back definitely needed a spacer, hit top of the coil mount without! could probably get away with a 5mm at the back if you weren't running 9.5 with a 15mm at the front. Had to go 20mm rear for look and handling characteristics. The clearance between the inner rim protector and the strut in the front however is roughly 2-3mm so JUST fits. Tires are stretched 225 and managed to keep the tread in the arch (rears fine, front just), can definitely lower the car in the rear with no problems, may need to roll arches or camber to the get the fronts nicely inside. One thing to note, these are LOUD rims, the thick flat wall of each spoke gives a very audible propeller like tone, and the spacers create a frequency at around 80kmh that begins to ring and never lets off as speed increases. So, if you're willing to loose a bit of that soundless s3 interior for that wiiiide super phat look, then its well worth it!
