I've got 4 lug wheels already so converting to 5 lug is not a option at the moment. I do want 4 lug disk brakes all around thou any recommendations for brake kits that will provide more stopping power the drums in the back scare me considering im running 600 horsepower.

My current set up is mustang 4cyl front brake rotor and spindle and the back have the 5.0 8.8 differential drums any ideas to make it work?

 

The '87-88 Tbird Turbo Coupe rear brakes are the way to do 4-lug rear disks. That's basically the kit you'll find on the North Race Cars link that chevydillan posted, or you can get the same thing from SSBC. (Looks like North's pricing is better, but I say that without actually comparing what parts come in each company's kit. You can also get the SSBC kits cheaper from other vendors than from SSBC's own site, like Summit.) Should be able to find used setups on Corral or Ebay or Craigslist.

Up front you should at least convert to the V8 spindles with the bigger (but still horribly inadequate) 11" rotors.
