i was wondering what the difference was between the 4 piston calipers that came on the turbo II and the single piston calipers that came on the base model coupe? does it just bolt up and all you need is new pads and rotors, or would i need to change the whole hub set up and all that fun stuff? it's something that i want to do, but i just want to see how much money i would need to save up before doing it. any information on this would be greatly appreciated.

 

I changed my single piston to 4 piston brakes. I had an S5 and was told changing BMC was not necessary. Everything bolted up fine, I changed the brake lines to the hardlines and had SS brake lines as well. Not sure if those were necessary either but eh oh well. You should try searching, I'm sure it's been covered before
