STOCK FLYWHEEL LIGHTENED TO 9 Kgs. GOOD or NOT ???

Hello guys. I've just had my standard flywheel balanced and skimmed to 9kgs from standard 12kgs. I've read that the best weight for road use would be 8. My question: is it worth it to take that extra 1kg off or leave it as is now ???
Will that kilogram make any difference ???
Cheers.

skimming flywheels is always a dangerous thing should you take to much off, as said above, it can shatter and smash through the gearbox, personally, i'd leave it at 9 kg and save for a decent light weight alloy one.

Id say you've already skimmed to much off and will have removed all of the hardening around the wheel..

Hope it lasts till you get your lightened one..

It's been done by Lateral Performance, so I'm guessing it's safe. They're know what they doing.

I have an API flywheel at 7kg. some are only 4kg!

What i have is good, but tbh re yours I'd leave it as it is now. After a while you gorget the difference you initially noticed (the problem with all mods, lol!)

An experienced and competant machine shop can take the O/E flywheel down to 7.5-8KG
This is something we used to do regularly but no longer. We have new ACT steel flywheels of 4.1 and 6.4 kg for £235 and the experience of driving one of these is streets ahead of a lightened O/E.
