find the How-to in the how-to section which has very good write up on the what you need and..... How to do it. :thumbup:

If after reading that you still have questions I'll be more than happy to clarify things.

im still confused on what size rim you need, i dont think the howto lists any definitive answer. 15" is the smallest that ive seen mentioned you can use with r/t calipers, right? why not 14" when they fit on the front?

If they fit on the front, they'll more than likely fit on the rear since the rear is for the most part, smaller.

the stock 15" will cover over the calipers on the rear but not on the front (if you were to SRT front brakes).

So are you talking about an aftermarket setup or the SRT-4 setup?? 15" rims will fit with the SRT-4 rear setup.

Sorry, I missed that one little point about the "biggest" because all my research has shown that there are no upgrades for the rear brakes in terms of a big brake kit. The only real kit made for the SRT is the Wilwood kit, which only does the front. There are some other kits out there, and information on SRT forums about them, in very little detail, but none that were practical in any manner or given as high of regards as Wilwoods. Their opinion is that the rears (once swapped over from stock drum to disc) are more than sufficient for stopping power.

Additionally, as you start going larger you have to keep in mind the bore size of your master cylinder and whether or not the larger brakes were designed to fit within the stock Master cylinder (15/16" bore meant for 4 wheel disc brake) giving you the necessary pressure needed for the upgraded calipers to work properly. This, again, takes you back to Wilwoods who feel that the front is the only place that an upgrade of rotor and caliper sizes should occur.
