j_jza80 Posted January 26, 2015 Share Posted January 26, 2015 (edited) Looking at various brake upgrades for the Supra, and just wanting some feedback on the various setups I have a budget of circa £1500 for a full brake setup to replace the crap J-spec brakes. I will be aiming to tune the car to around 550hp at some point in the not too distant future, and I only want to do this once. So far, my thinking: UK front and rear brakes. Pros: - Within budget - very powerful brakes - well made - good selection of discs and pads available & OEM support Cons: - VERY heavy. - Caliper pins are a pain K-sport/ D2 budget big brake kit Pros: - Much lighter than UK brakes - Improved pedal feel over UK brakes Cons: - Quality?? - aftersales/support issues? Parts availability. - Blingy look - would have to increase budget slightly - Noise? LS400 front brakes Pros: - Much lighter than UK brakes - Much more affordable than other options - pretty much bolt on - OEM levels of support, parts supply etc - good quality - Much more maintenance freindly than UK brake design Cons: - not as fade resistant as UK brakes - poor choice of discs/pads (though improving, CW even offers pads) - No definitive answer for rear setup. Most people use J-spec rears, but surely the brake bias is totally off? Using UK rears is an option, but effect on brake bias...? Premium brake kit - Brembo/Alcon/AP etc Pros: - best performance - best choice of pads/discs - look the nicest - Excellent aftersales support - best quality Cons: - VERY expensive - expensive replacement parts - Overkill on a road car?? - Some setups are noisy Purely from a value for money point of view, the Lexus brakes are looking very attractive at the moment. The decrease in unsprung weight is a big plus too. My car is predominantly a road car, although I do drive it how it's supposed to be driven Probably my least favourite option is a budget big brake kit. My first Supra was a UK spec and I found the UK brakes to work well, though they didn't give great feel, were a PITA to work on, and weighed loads. My second one had Brembo F50s on the front, UK rears. Great setup, much improved over UKs IMO, though replacement parts were expensive. My subsequent 2 later Supras both have J-spec brakes, which are rubbish IMO. Thoughts?

CanisLupus Posted January 26, 2015 Share Posted January 26, 2015 Cons: - VERY heavy. - Caliper pins are a pain Re Pins: http://www.mkivsupra.net/vbb/showthread.php?315042-Stainless-caliper-pistons-stainless-pad-pins-for-UK-calipers-caliper-seal-kits Go with the EU/UK Spec brakes.

Best Choice for the Street. Can't see a D2/K Sport anywhere near that setup. If I went with UK brakes, I would definitely go with those parts My concern with them is mainly that the calipers weigh a hell of a lot, around twice the weight of the Lexus, Brembo etc calipers.

Just go UK setup. Im just on rebuilding mine with the CW bits but they were more than capable before.. Plus it all just fits no messing about.

Dnk Posted January 26, 2015 Share Posted January 26, 2015 Why is weight a problem, are you building an out and out track car ? even then i doubt very much you'd notice if they weighed the same as Brembos Quote Link to comment Share on other sites More sharing options...

As Dnk has asked. Why is weight a concern? If you had the intention to track the car and do lots of weight loss on other bits then i would understand but as a street car there is no point Quote Link to comment Share on other sites More sharing options...

Seems like a no brainer to me Plus, once you've had the experience of drilling a UK caliper to remove a slider pin, you'd be reluctant to use them again too Quote Link to comment Share on other sites More sharing options...

I will be doing a little weight saving in places, such as removing the pretty useless rear wiper mechanism, forged wheels, battery and any other areas I can find some reasonable savings without impairing day to day comfort Quote Link to comment Share on other sites More sharing options...
supersizejim Posted January 26, 2015 Share Posted January 26, 2015 Sorry to but in?? But has anyone used or got Wilwood Brakes? Looking at a set of 4 piston ones for the front with 345mm rotors. They must be better than my UK fronts? Quote Link to comment Share on other sites More sharing options...

bignum Posted January 26, 2015 Share Posted January 26, 2015 Ive got the Brembo/F50 setup on the front with uk rears and must say they work great but somehow feel alot better than my uk`s ever did, downside is disc prices, however if we could still get decent race pads for the uk`s i`d have stuck with them.

Wez Posted January 26, 2015 Share Posted January 26, 2015 Great thread here comparing various configurations, might be worth seeing if someone can get hold of DanDan so the images can be uploaded and hosted on the site instead of photobucket as sadly it appears mostly broken now http://www.mkivsupra.net/vbb/showthread.php?225007-Big-Brake-Kits-Real-Numbers Quote Link to comment Share on other sites More sharing options...

I found that too, and I wasn't even running a master cylinder stopper on that setup. Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted January 26, 2015 Author Share Posted January 26, 2015 Are you putting a nice small quick spooling single turbo on yours J? Yeah most likely either a GTX3076R or GTX3582R, Whifbitz manifold and Syvecs. Simple, reliable, responsive setup. Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted January 27, 2015 Author Share Posted January 27, 2015 No need to wait for Syvecs, all the wiring is already installed for you. I honestly can't stress hoe much it transforms the character of the car if you ever find yourself in York, you're welcome to try mine.
