yes.. check this link, you'll see an exploded view of the GSR:
http://www.cenracingdirect.com/images/gsr.htm Look at the engine and flywheel setup. Below are the parts I recommend. You may notice dfferent part numbers listed for the clutch shoes and springs. These are upgrades- stiffer springs and billet aluminum clutch shoes. This will allow the engine to wind up higher before the clutch kicks in.
G36221- screw
G73902- front bearing.
GS301- Front pinion gear
G36904- shim
GS300- rear pinon gear
GS318- GSR clutchbell
G73902- rear bearing (same as front... but get extras)
MXS21- GOLD clutch springs
GSS16- heavy duty clutch shoes. Comes in packs of 4, but you only use 3.
MX268- Matrix R2 pilot nut. (easier to get clutch springs on and off)
MX053- Matrix/GSR Flywheel
G70349-20- Flywheel collet
