rob wild Posted May 2, 2006 Share Posted May 2, 2006 Yes but as you said you need to change the disks, pads and calipers etc check this website out: http://www.sixplus.co.uk/suprabrakeswap/ I'm sure if you do a search as well you will find loads of stuff on it Rob Link to comment Share on other sites More sharing options...
terribleturner Posted May 2, 2006 Share Posted May 2, 2006 There's a shield around the j-spec calipers that needs to be got rid of but that's it. Fairly easy job and one i wish i had done myself instead of going to a garage. Link to comment Share on other sites More sharing options...

Jspec Germany Posted May 2, 2006 Share Posted May 2, 2006 I'm taking this on with US spec fronts as soon my braided lines arrive. Link to comment Share on other sites More sharing options...
TrickTT Posted May 2, 2006 Share Posted May 2, 2006 Make sure your wheels will clear the uk spec calipers as well or it could turn out to be a very expensive weekend. Link to comment Share on other sites More sharing options...

Hi What wheels do you have on your car? As said, make sure they will clear the 4 pot calipers, I have attached a cross sectional diagram to help you measure the wheel clearance. Alternatively see if there are any members near you with the larger brakes fitted that you can test fit your wheels on. I can supply the larger spec 4pot front and 2pot rear brakes at very good prices, I've supplied dozens of sets to forum members. Some pics and prices on THIS THREAD. I also have a full delivered price list of all the parts required to upgrade to the larger brakes, if you can email me at the address below in my sig I will send you a copy. cheers Link to comment Share on other sites More sharing options...
DaveMassie Posted May 15, 2006 Share Posted May 15, 2006 Can defo recommend Nics deals, he's the man to speak to about getting the uk brakes at an excellent price! Link to comment Share on other sites More sharing options...
Hak Posted May 16, 2006 Share Posted May 16, 2006 Simple question but what sort of performance difference would you expect changing to UK brakes? Thanks Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 16, 2006 Share Posted May 16, 2006 Longer pad life better fade resistance, firmer pedal, potentially a better feedback. Over say a couple of emergency stops I doubt whether they'll make you stop in any shorter distance though. Link to comment Share on other sites More sharing options...
Pete Posted May 16, 2006 Share Posted May 16, 2006 It's the larger surface area that makes the greatest difference after all. Link to comment Share on other sites More sharing options...
n00b Posted May 25, 2006 Share Posted May 25, 2006 in the guide it says to bleed the rest of the system... is there any procedure for this e.g. if i am only changing the rears do i need to bleed the front brakes aswell... and when i refill the brake fluid is it just a case of filling the brake fluid up in the engine bay to somewhere between min and max? sorry for dumb questions n00b Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 25, 2006 Share Posted May 25, 2006 It's the larger surface area that makes the greatest difference after all. Hmm, not quite right. Greater disc diameter adds brake torque, more surface area gives longer pad life and an ability to run a softer compound, additional disc width helps heat soak, but diameter and width also increase inertia.

gaz1 Posted May 25, 2006 Share Posted May 25, 2006 and while bleeding, turn them upside down otherwise you may end up power bleeding them,mine were a pig to do until they were turned upside down Link to comment Share on other sites More sharing options...

If the pedal feels at all spongey I would bleed them all. I find the MKIV very easy to bleed. Personally I have never had to anything more than get Jane in the seat and bleed conventionally, no need to do anything unorthodox. Fill reservoir to full mark if rear pads are new and fronts are under half worn. Otherwise the fluid light will be flashing under hard braking. Lube the slider pins with a high temp moly grease.

AlanM Posted May 26, 2006 Share Posted May 26, 2006 I'm taking this on with US spec fronts as soon my braided lines arrive. Thought if you upgraded fronts you had to upgrade back as well? Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 26, 2006 Share Posted May 26, 2006 Ideally you should indeed, but as the fronts will be working better than the backs to an even greater extent the ABS will save any really bad lock ups, but for best results you need UK discs and calipers on the back as well.

Jspec Germany Posted June 1, 2006 Share Posted June 1, 2006 They're on the list, believe me. Just have bigger fish to fry at the moment. Next trip to the states, I'll be picking up a set of rears. Link to comment Share on other sites More sharing options...
