Iv got my motor out to replace it and am going 2 lighten the fly wheel while its out. I normally just aim 2 take 10% of the original weight off. Is this ok or is there a better way??

then one of these http://www.maperform...ml#.UZN1HUpU1JQ
safer than machining a cast flywheel....plus no need to rebalance

you can take shitloads out,

a member on here used what you posted i think they had to get custom flywheel bolts cut because the evo fly uses a larger bolt than the 93

I will have to check that...I thought they are the same with the exception being the 93 is longer than the 63

Im bit tight 4 cash atm. Can lighten myself 4 free and would rather spend da cash on evo injectors, afm and ecu. Think ill just aim 4 the 35% at this stage. Thanx any way. Will up date this after machining.

That would be me, I had to get custom bolts machined. They are different from the 4G63T bolts and the stock bolts are way to short. But it runs great now. Although the clutch engagement has become quite rough with the light flywheel. Also I don't notice massive difference in acceleration but all bits help I suppose

Machined it up Friday. Weighed 8kg at the start brought it down to 6.4kg and there is still plenty of meat left on it. Was aiming for 6kg but it was 2am, I wasn't on the clock any more and couldn't b bothered clocking it up again.

for the minimal price for balancing, get it done, end of story.
