    I have a non-ABS EP82 GT turbo. I intend to go big brake and I have identified 4 piston calipers off a celica gt4. Now I know several people have done the conversion, am wondering what's the best discs to use with the calipers. I want to maintain my current 4*100 stud setup. And will I need to change my master cylinder given the additional 6 pistons. I could go with MR2 twin pots but I like the celica 4 pots more :)

    Also, I am researching on adding ABS (I know!!). Given some models came with the ABS option, I assume all I need is to find a way to add the ABS pump and control module. Am I right? Forgive my naivety, am not too knowledgeable in vehicle mechanics.

    For the big brake kit, I have found several options on ebay:

    Hey bud, to add abs you would also need the hubs, wiring looms, abs ECU, wheel sensors and possibly an abs rear axl not sure on that one tho, just forget about it, too much hastle :)
    Where abouts are you ? Them calipers are very very expensive, could probably get them in the UK cheaper.
    I seen them fitted to a glanza, used the gt-4 discs too, he had the disc re-drilled to 100x4 and im near sure they where turned down to 300mm, 16 inch rims will be needed too to clear them and the car i saw also had 27mm spacers to help with clearance
    Phil m on here sells big brake kits for these, straight fit too but think they are like 600 pounds, a few local owners have them fitted
    I'm going down the twinpot gt-4 caliper and vauxhall cosra C sxi discs, straight fit :) they are shown in my thread

    Hello,
    Thanks for the response. Woah I never thought it was that much effort to add ABS. I guess I will just leave it at that. Am in Kenya, but I buy items from the UK too and ship them here. It's cost effective. I think I will follow your lead on the gt-4 calipers.

    I believe the calipers are from the gt4 st185 and not ST165, right?
