i've just bought some 320mm discs for my nc does anyone know if i can buy adapter plates for my standard calipers so i can use these discs.

No. I know you can use 310mm discs if you get some 99/00 (I think) blade calipers on the normal blade/sp1 etc brackets.

what calipers are you using?

i'am using standard nc30 calipers the discs are from the rc45

Think you will need some bespoke brackets. Don't know if anyone runs 320mm discs that use the std calipers.

RC30 used 310mm calipers and so if you got some of them rotors then you would be good to go.

Perhaps one of the old skool gurus might have an idea for a solution but I am failry nerdy and don't recall any fix for it.

as an aside..do the discs fit the std wheel? what caliper fitment have the RC45 got? if they are backwards compatible with the sp1 caliper fitment you are sorted...but I don't know.

I would PM "RVF" on here - he knows the score and has a kickass RC45...

The stock RC45 and HRC RC45 uses 310mm disks not 320's.

If they are for a stock RC45 the off set will be too great to fit in the 400's legs. Though their PCD is the same.

Brembo did make some narrow track 320's for the RC45 but these were used with non OE disks and cant be used with stock calipers and need to be run with Brembo narror track pads/calipers.

Speak of the Devil...

Lo, he shall appear!

What are you doing with the bike? The standard discs and OEM pads are more than adequate for all but heavy track use / modified bike.

With braided lines / good fluid and pads the 30 has wicked stopping power on standard calipers / discs... There are adapters available for SP1 calipers to be fitted

i lust like the look of the rc45 discs cosmetic realy oh well perhaps they will be on ebay soon.
