Ok so i already upgraded my front brakes to sn95 and 5 lug rear drum but i would like to put cobra calipers and 13 in rotors on, along with upgrading from drums to rear disc. a friend of mine has a complete rear disc kit but it comes with 4 lug rotors. if i buy sn95 5 lug rotors and just use them with the provided calipers and brackets, will it work? the second question is, the kit comes with a svo master cylinder, will it be enough to power the front cobra calipers and rear discs? and would i have to change my brake booster? i will have pics of the kit later tonight

If the 4 lug rotors have teh same dimensions as 5 lug, and they sit in the same spots on the calipers, they will work.

what about the master cylinder and booster

88_cobra

here are the pics of the kit. i measured the 4 lug rotors with the 5 lug rotors and the are the same diameter but the 5 lug were not vented like the 4 lug so they are wider. somebody please help with the master cylinder. i know that someone has done this before.

I believe if it is a master cylinder for a cobra then you need to buy a proportioning valve that would work with the master cylinder. Thestock GT/LX had a 7/8 inch piston in the cylinder where the cobraI think has a 1 inch. Itbolts up to the boosterbut the brake valve needs to be replaced for routing to the front .Google it I believe there are many sites that sell the valve.
