A lot of guys are using the Novitec spacers with the 11mm front and 15mm rear. They want ~$950 for a set of four. I also talked to exotic car gear and they want $1K for a set of four INCLUDING Titanium Lug nuts. The challenge here is that they are recommending 15mm for all four corners. Is anyone running this setup? Is it too aggressive in the front? Anyone running this with a lowered car?
