Evo and vr4 calipers are exactly the same except for the line fittings. And I bolted vr4 calipers to my gsr lancer hubs. Dunno about the shocker or ball joint mounts though...?
How much for the brake booster. Does the Evo 2 have abs. How does that system work. Is it in the brake lines or the booster. Coz my rears have the plugs but I don't have the system. Just seeing what I'd need to get abs working
