hello guys
I got an l5 zxr 400 and i found a full braking system of a gsxr 600 02 an a good price so could you tell me if the calipers fit straight on my zxr??
Or do i need spacers as for the gsxr 1000 01-02???

The gsxr model is this

And the calipers i think that are these




What do you think
Is it a good upgrade (i mean WITH the master cylinder) or i need to look for gsxr 1000 ??

They fit straight on with a 1.5 mm spacer needed to get them to centre on the disks.they are m8 bolts for them.The zxr ones are m10 so best solution is to make up a top hat type spacer any decent machine shop could do it or think somebody was selling them on ebay a while back. the 6 pots from the 1000 are the same deal.But go for the 4 pots.hope this helps.

Why do you suggest me to go for the 4 piston calipers and not the 6pot ones???

Are 6pot ones too strong for the little and light 400??
