Brian / Jim - I notice that the rotors you linked above are replacement for the 94-06 Connie, so they are 300mm, not 320mm.

If you want 320mm for exact fit on the 94-06 Connie, look for replacements for the following bikes (among others) which came with 320mm stock and the correct bolt pattern / offset:

93-01 ZX11
00-03 ZX12

The 94 thru 06 rotors are 300 m/m, 320 would be over size for the stock brackets

True true. I think the better upgrade for the newer models would be just a better caliper.....300 is already a decent size. In my case, the improvement was pretty huge going from a stock 270mm with a single pot to 320mm with 4 pots.

I agree. The biggest improvement is definitely the caliper. I also used the GSXR-750 Tokico calipers with the stock 300m/m rotors. I probably wouldn't go to the 320m/m rotors unless/until my 300's go bad.

It's the calipers that make the biggest difference, increasing from 300 to 320 discs will only give a 6.7% increase (torque = force x radius). When I did the upgrade for the earlier models I calculated there is 33% more pad area and 133% more piston area.

So I am looking for info on the 4 pot mod to the older Connies. Cost? Parts needed? Thanks


If you're using the stock size discs of 270mm diameter I can supply brackets to suit Nissin 4 piston calipers, I don't have any in stock at the moment though. See link below:
