Quoting pyro719:
My car came with a 5 lug swap and the brakes are horrible. Is there a way to get bigger brakes off a different car to work with the gvr4 with 1g 5 lug swap?
The factory braking set up is very good, as others implied, there's likely something actually wrong with your system, maintenance will bring it back up to spec.
unless while fitting a 5 lug swap they went down to single piston brakes?
