Starting this thread with the hopes of reducing the number of 5-lug or general brake upgrade threads that have been appearing on the forums since most of the major brake conversion sites have gone down. This thread will be strictly informational, and any off-topic banter or user specific...
Either SN95 GT/V6 or Cobra is your main options. Given that you have the stock 10.8" brakes up front, I would recommend the 94-04 GT/V6 setup. You will need to change the master cylinder however.
94-04 Rotors
94-04 calipers
94-04 pads
94-04 GT/V6 caliper brackets and anti-moans
94-98 axle shafts
parking brake cables for specific year you have
If you want to keep the stock fox width out back, you'll need the offset caliper brackets from north cobras or LMR and the fox length 5-lug axles with SN95 flanges sold at LMR
1993 Cobra master cylinder
3-2 conversion
plug to gut the prop valve
adjustable pv.
Expect to spend $300-1000 depending on where you source parts from and ratio of new to used parts as well as what axles you go with.
