I think the flywheel is 6 bolt on the z20leh.

The leh has a bigger diameter clutch than the z22yh / z20ler, think ours are 228mm and the leh is 240mm, so would still probably fit

I just realised why TTV screw up the z22se M32 flywheel, they probably use the z20leh spacing, so one bolt hole will need machining a couple of mm as it's offset on the leh

took a sketch of a z20let flywheel today and have been informed the dual mass of the vxr has the same hole pattern altho i cant tell from the pic if theres is a bolt out of place lol

If it helps a C20LET flywheel is the same as the Z22SE so may be easier to check if the C20LET is the same as the Z20LEH, as it's probably a more searched out question
so the c20let has symmetrical hole spacing ? but there not dual mass for the conversion i need the extra width of the single mass conversion flywheel to meet the splines on the m32

had another closer look at the scribble of the z20let one and one hole is just off by about 2mm like vocky said

Holes aren't symetrical, same as z22se.

Other option is to space the release bearing from behind.

EDIT: just realised you need the clutch to sit out further.

the z22se one has a symmetrical pattern i ment :)
tryed the z20let doodle under the z22se on you can see the one hole difference

or ttv are just sending out astra vxr flywheels to suit lol

new fly wheel is in the post and ive got to ring back for the clutch once i confirm the flywheel is suited
