Stratty Posted August 5, 2007 Share Posted August 5, 2007 Hi guys, I imported my car about 3 months ago and would like to upgrade the brakes. I have heard that J-Spec brakes are smaller than uk spec ones. Is this true? If I want to upgrade my brakes, am I limited to what I can put on, if so, any ideas of what I can get. Cheers for your help. Stratty Quote Link to comment Share on other sites More sharing options...
Trig Posted August 5, 2007 Share Posted August 5, 2007 Yup Uk brakes are bigger and you will definately notice the difference! There are obviously better brake kits out there, depends how big your wallet is Quote Link to comment Share on other sites More sharing options...

DaveK Posted August 5, 2007 Share Posted August 5, 2007 Bear in mind that if you swap to bigger brakes, you will need bigger wheels (assuming your car has 16" which most J-spec's do). I bought UK 17"s a couple of months ago because I was going to put UK brakes on, but I probably won't do that. So if you do need stock 17s let me know.

Stratty Posted August 5, 2007 Author Share Posted August 5, 2007 I already have 17" alloys on it so I suppose thats one problem solved. Just not too sure what size/type brakes I need to upgrade. Any ideas??? Quote Link to comment Share on other sites More sharing options...

Steve Posted August 5, 2007 Share Posted August 5, 2007 Just try and find a complete UK setup for the Supra. They are 4 pot brakes up front and 2 pots at the rear. These are more than enough for most people. Quote Link to comment Share on other sites More sharing options...
Nic Posted August 6, 2007 Share Posted August 6, 2007 Hi Stratty Referring to them as UK and J-spec brakes is a bit confusing, as many of the J-spec cars came with the larger spec brakes as standard also. So first of all I'd establish which brakes you have fitted, post pics if you're not sure, so we can identify them. Smaller spec brakes 2 pot front calipers - 296mm diameter discs 1 pot rear calipers - 307mm diameter discs Larger spec brakes 4 pot front calipers - 323mm diameter discs 2 pot rear calipers - 324mm diameter discs Upgrading to the larger spec brakes would be the first mod I'd do on any Supra running the smaller brakes, the difference in braking is significant. Pics of the larger spec calipers here: http://mkivsupra.net/vbb/showthread.php?t=98436 cheers Quote Link to comment Share on other sites More sharing options...
