Quick question:



Can 89-91 1 piston brake calipers be used on a 91 that originally came thru with 4 piston?



Is the bolt pattern width of 6.25in the same as that of the 1-piston caliper?



Thanks!

 

yup they are interchangable but you must also change the brake line, i upgraded my GTU to 4pistons.....

 

cool...thanks dude

is the proportioning valve the nozzle that feeds the brake line into the caliper?

since were talking about brakes. Does the GXL have 4 pistons all the way around or just in the front. Also is there anything i can use off the GTU for my GXL that would be an upgrades. Im gettin ga new suspension setup so i wont take the GTU's

the config is 4 pot up front, single in the rear.



Not sure what came on the GTU... i think that was considered the base model in canada between 89-91 so it might only have the single piston front caliper.

 

all 2nd gen rx-7's have single piston out back but the base models have solid rear disc as opposed to the non base models have a vented rear disc
