parts wont be cheap bub, as a lot of show ponies with lots of $$$ will want to have pretty brembos on their 08's etc. Think the other options already mentioned are the best, however always do the MC first as the best gains are here
I can definitely see that if your moving from 2 pot sliders like SV calipers that there would be a huge improvement, but those moving from other 4 pots like Nissins or Tokicos - Is there that much of a noticeable improvement
The Yamaha r6 /R1 Sumitomo monoblock calipers may not give you more braking power... But, they do give you better feel than what you can get from the GSXR Tokico 2 piece calipers... Another thing you can do to improve your GSXR brakes, is to install a Yamaha Brembo master cylinder... Much better than Nissin master cylinders... Luis
quick google search tells me 108mm, like rest of japa stuff, discs are 308mm. 'Twin 308 mm (12.1 in) floating discs, Nissin 4 piston radial monobloc calipers' and this also http://cgi.ebay.com/ebaymotors/09-1...MONOBLOCK-CALIPER-/270700891450#ht_500wt_1182
Correct me if I'm wrong but that's the disc diameter, not the offset. The offset is the distance from the caliper mounting points to the disc
For stockers the NISSINs from the 07+ zx6r & ZX14 is an amazing performing caliper, though not a monoblock their performace for feel beats my M4 brembo monoblocks on my 1098 without a doubt and offer 98% the same performance. The nissins on my triumph 675 are always pretty amazing.
The '09+ Triumph 675 Nissin monoblocks are 108mm. I bought those one off Ebay and replaced the 2 piece Nissins on my '06 675. They are lighter, more rigid and give better feel and that was going from Ferodo CP211 pads in my 2 piece to stock pads in the monoblocks! The down side to the Nissin monoblocks are limited pad availabilty right now. Only Ferodo XRAC, SBS, and EBC HH pads are available. Corbon Lorraine are coming soon. I wanted to run RJL's but no go as of yet. Went with the XRAC. Also running 19rcs Brembo m/c with Spiegler race lines.
