lol funny you should ask I was actually looking at the brocks spacers online not more than 5 mins ago! I made some washers for my clutch pack but I kinda didnt measure something right so they wouldnt fit into my pressure plate. Honestly I know anyone can make the spacers but its hard to do if you dont have a lathe. brocks sells them for 30 bucks. maybe we can get a group deal going on or something???

On my built motor I got these springs from barnett that were like 100lb springs stock are like 65-68 if i recall correctly. I might get those springs again or just order those spacers from brocks.

yeah the thing with barnett which people dont understand is they advertise their products sorta wrong, only select modles have heavy duty springs, they dont make ones for the 10r that are heavy duty they are actually the same spring rate as stockers! the 100lbs springs I got from them were awesome though! pushed close to 230hp on spray numerous times and did a top of top end stuff and the never let the clutch slip!

but yeah as for spacers I was going for about 5mm myself. I had 2 washers that were right at about 2.5mm each and was going to double them up.

All you have to do is call MTC and they sell the shims in all different sizes if thats what your looking for....Also, ZX-SIK-r where did you get the Vesrah Clutch springs at and what is the part number if you can recall. Im about to do a Clutch Spring Pressure Test with the Stock Clutch Springs, Barnetts, Orient Express, Vesrah, EBC and DP Brakes Clutch Springs to see which ones have the most spring pressure. Just trying to help us ZX-10R guys out since our aftermarket isn't as strong as the Gixxers 1000's. My mechanic has two badd ass Spring Testing machines that we are going to find out which ones are the best and which ones have the most consistent spring pressure within a complete set of springs....Please advise !!! I will post my findings under this thread after the testing has been completed...Results will be about another three to four weeks as to im getting ready for the AMA World Finals in Valdosta Georgia.

I talked to Barnett today and they said stock springs are about 62lbs pressure They make a 75lbs 85lbs and a 100lbs spring for the 10r.

I just ordered mine threw them a set of 6 is like 22 bux or something Barnett clutch number for 100lb spring is ( MT-91-6 )

if you blow threw a clutch with those springs your pack is junk or yor making crazy hp lol.... btw you cant have girly arms with these springs!

reason why I got them is because when you ring the bike to top speed a few times a day the pack gets very hot!
