Brake upgrade or stay stock?

I'm needing to replace my discs and pads in the next few weeks on my newly bought SZ-R, they are still Jap spec brakes.

Who is the best company to approach for discs and good pads and what sort of cost am I looking at? Also, what is the rough cost of upgrading to UK spec brakes and what are the limitations of doing it?

Cheers all.

See the Import Pimp (Nic) for great prices on UK spec brakes!

Make sure you also change the master cylinder along with all 4 discs and calipers.

Good advice there John

and... if you go UK set up - make sure your wheels will fit over the calipers -

UK spec deffo way to go, anyting more is a bit of a waste of money imho.

think it cost me around a grand for full set up, uk calipers front/back, disks, race pads etc. worth doing the lines while youre there.

...n make sure you get the shim pad things (fitting kit), did mine without n they make a right clunky racket!

i dont think youd need UK spec brakes on an n/a just get some fast road pads trd or chris wilson ones.

well I've got UK spec brakes on my N/A and I don't actually think they're 'that' good... god knows what Jspec feel like.... I'm thinking of upgrading mine..

Its the stopping of the weight at high speed where they matter, doesnt make any difference if its NA or TT, you can still get up to high speeds where they make a big difference.

derrr... thought it sounded a bit odd... must be the end of the weekend.. I was thinking what the hell has that got to do with stopping...

Why? Never had a problem with mine on J-spec m/c.

You don't have a problem, but neither does it work as it ought to.

There is a specific ratio of master cylinder to caliper piston area.

A smaller cylinder will also work, but won't control the pistons properly.

Some weeks ago I was having a chat with Matt Harwood, and he is somewhat underwhelmed with UKSpec brakes - the man has done a fair few conversions, so he knows.

That is *not* my experience though, and the JSpec leftover parts might explain that discrepancy in performance.

Not sure about the ABS proportioning valves either.

...and don't get me started on aftermarket wheels (which could well dissipate the heat from the brake disks at different rates to the stock 17" - warped disks anyone?)

No warped discs here, 4 years later and 2 Nurburgring weekends.

Interesting, my front brakes clunk when I go from forward into reverse, wonder if mine are missing the shim pad things...where does one buy such items?, Toyota?

Shims wont stop that clunking you're talking about Carl.

How can you identify between a jap/uk master cylinder?...does the UK one have a picture of the queen on it

No seriously, how can you tell?

I've decided to remain on the J-spec system but chnage the discs and pads...

any advice on the best disc/pad combo and where I can get them??

Cheers again guys, I getting abit fed up having to repack the parachute everytime I need to stop....
