Which 13 inch front brake kit?

[motorcitydak]

I will be running 13 inch brakes in the front and need help deciding which one to get. It is between the Dr Diff kit which uses 2 piston ford mustang calipers iirc for 800 or the Viper brake kit with 4 piston calipers for 900 but I need the A body spindles. I am leaning toward the Viper setup to keep it Mopar and to have 4 pistons instead of 2. Any other opinions?

Dr Diff kit can use B/E spindles as well. The Cobra calipers are made by PBR. These same calipers (sans the "COBRA") were used on C4 'vettes as well.

You can use the taller FJM and late B body spindle instead of the A body units. Much easier to find. ARE has also come up with some other rotor options that may provide more choice in applications and pricing for the kit.

Four pistons will provide better feel at high speed than the two piston design and the Viper caliper is made by Brembo who makes calipers for a number of high end performance applications. Ultimately, the choice may come down to who has the biggest pad selection for the prices you feel are reasonable.
