Personally I'd be wary of doing it myself as a failed fly wheel could do some serious damage. Keep in mind where the gearbox is in a 7 type car
and how close you are sat to it.

You should only remove the weight from the rear edge and not much
IMHO you can pickup a steel one of eBay for £70 or so, they are stronger and safer

Hi ALL
Sorry for any misunderstanding I would not even think about doing myself I have seen some horrible disaster when the fly wheel has snapped off cutting
through the bell housing so thanks for all your concerns.
What I was really asking:
a) is it really worth it if I am not going on the track?
b) is it really enough on its own?

Is it worth it?
You need to do cost vs performance gain for this and any other mods and decide on the numbers that come out.

Absolutely worth it yes, it will not make a lot of difference in the high gears, it should transform 1st and second.
I started with a DMF and heavy 11" clutch it weighed in at 28kg, put in a solid flywheel with 9" clutch and 6 paddle driven plate, car now
spins up its rear wheels on acceleration in 1st, which it would never have done before.
I did take a fair bit of weight out of the cast wheel, not to everyone's taste, it was checked and balanced up by an expert.
Straight 6 so naturally balanced which helps.
This is why bikes Rev like fury!

Hi Mark

Personally I would just buy one that was designed to be light rather than lighten a standard flywheel. I once saw a supra at work with a machined
flywheel. It let go putting a hole in the (luckily) passenger footwell.
I do like the revvy nature of a really light and balanced flywheel. The flywheel in my Xflow weighs a measly 5kg's. It revs QUICKLY but still
very driveable.

It's a big spinning lump, you want to concentrate the weight as close to the middle as you can as it has less affect (further the weight from
the centre the more it has to move to accelerate it) hence fitting a smaller cover and driven plate provided it can handle the torque even if it
weighs the same however to spin up I s effectively less. I have a ceramic paddle driven plate as it can support the torque in a smaller package.
The next step up for me is a twin plate setup, again reducing the distance from the centre of a crank + lighter as well

You may find a light flywheel a pain in normal driving careful use of clutch and throttle while starting from stopped.

Most light flywheels are fine for the road, only the really really light skeleton ones with a very lumpy cam are difficult on the road.
I fitted 2 steel 6Kg flys to Pinto's 1 with a lumpy cam.
Even with the lumpy cam I did not notice a down side but the engined revved better especially in low gears countering the off cam feel.
