I like the wilwoods because they are reasonably priced, well made and readily available. There are a number of other really good, arguably better (such as AP who I am huge fan of), manufacturers out there but wilwood works for me. I like curved vein rotors of sufficient mass (since wheel is a limiting factor, you are looking to go wider), large pad surfaces and differentially sized multi piston calipers. If you are going to do some upgrades, take some measurements (temps etc) from your current system before you begin. IMO, chassis setup is #1.

Many folks sell and use and aluminum mounting bracket and I flat out don't approve. You can get the same setup with a 1.38 inch rotor that would add about 17% more mass if need be. Personally, I don't look beyond Wilwood or AP unless I have to. Wilwood for a more budget friendly weekend warrior and AP for all out racing. Not all the products are great. Such as Wilwood clutch slave which must be someones idea of a joke. Sure, they work but whom ever designed it needs to go back to school!
