I need some front discs with the diameter of 310 mm and the same bolt pattern.Where can I find or from what models I can buy them?Apparently the cbr600rr has 310 mm front discs but don`t know if they fit the nc30 front wheel.Let me know.Thanks

You have 2 options..

Buy some RC30 discs...they are the same fitment and 310mm

Or get a rotor kit in 310mm size from Stealth products..

Is this for a ZXR conversion?

yes it is

Well...there you go!

I have Stealth rotors on my road bike and they are spot on. You can get a full set of discs for £195.

Is this for a road bike or race bike? If a race bike, might be woirth asking EBC if they have any RC30 discs in their sale (brakes4u)

There were some discs on ebay recently - they sold for £102 and they were Stealth...I nearly bought them

I bought them CMSMJ1,free postage to.

You sure about that? The NC's are 74mm PCD with a 58mm id, the 98 99 900rr is 78mm PCD, 62mm id, the CBR900 also has a different offset, 17mm for the NC to the 98/99 CBR900's 21mm.

BTW rotors from a 92/93 CB1000 (the big one) will work..

hi thats what i was told but the more i look into it your right sorry

No prob RATMAN. Here's a gem of a site from Australia that gives you a lot of those measurements for brake rotors. http://metalgear.com.au/searchByBikeModel.php
