I have an '86 lx that originally had a 4cyl. It has 10" rotors on it. I would like to put brakes from an '87-'93 5.o. They have 11" from the factory. Is this correct? If this is so what do i need to do this? Are there any companies out there that sell a complete kit. Also i already have draglites for the car so i want to keep the 4 bolt pattern. I drag race the car and are looking for more stopping power. Will i see much of an improvement? THANKS for any info.
