The ones I'm looking to get made are a two piece fully floating set up. And the reason is that the oem ones are OK under normal circumstances. But when you now have a 218mbh car... it would be nice to improve the stopping power a tad. Without the expense of ceramics
The discs are coming in at just over £1200 to have made by this company
