What is required to change my GTu over from the single piston calipers to 4 piston calipers? Is it just a direct swap, or something more involved?



Thanks.

you need the rotors caliper and lines for the front. i dunno if the rear is worth doing or what you need to do to make it vented

Would the generic Brembo rotors from eBay work?

here I thought GTu had 4 piston brakes?

Nemesis

Nope, single piston.





I'm just trying to convert the front brakes.

it works like this rob



86-87 sport, gxl and turbo get 4 piston brakes

88-88 gtu, gxl and turbo, and vert

89-90 gtus, gxl and turbo, and vert

91 coupe a package or better, turbo and vert



everything else in 86-88 gets 4 lug, and 89+ gets 5 lug single piston

So I just need rotors and lines for a turbo car?

the S5 GTU has a funky single piston setup, which afaik is not shared with other FC's



the rotors are the same as for the 4 pistons, but you're gonna need the front mounting brackets for the 4 piston brakes.
