Out of interest what size offset have you moved from - to? Wheel sets are extremley expensive. The cost you quoted is the same for my 194Ms
Scary prices
Previous setup:
Front: 18'' 8.5j +45 with 225/40/18 Potenza's
Rear: 18'' 9.5j +40 with 255/35/18 Potenza's (using a +25mm spacer)
New setup:
Front: 18'' 8.5j+25 with 245/35/18 RSR 595's
Rear: 18'' 10.5j +12 with 285/30/18 RSR 595's (no spacer)
The fronts should now be sitting flush with the stock arch line, but also thin enough not to cause rubbing issues on full lock.
Rears have eliminated the use of a spacers (which I never liked) and will push the wheels out another +10mm so should be close enough to the arches without destroying them over bumps.
Whole setup came to about a grand, but my selling my last set helped soften the blow.
Pretty mad that my last set went to a supra in Africa of all places, never thought they would make it one piece
