I used to have greenstuff and they were great, no problems.

I have axxis ultimate now (a step up from metalmasters, the sh*t that comes with stoptech race packages:thumbup: ) they are REEEEEEALLLLLY nice. I got them for $85 shipped, all 4 corners on groupbuycenter.com. Go to groupbuy and look for a buy from raceconcepts.net. I have bought from them several times, and am extremely happy with their prices and fast shipment.
