In this video I explain the advantages and disadvantages of lightweight flywheels.

RX8 RACING BEAT ALUMINUM LIGHTWEIGHT FLYWHEEL REVIEW
I installed the Racing Beat Aluminum Lightweight Flywheel awhile back and have put together a video on my thoughts on it. It gives you better acceleration, but I think it took away my top end. […]
The easy answear is if you have a lot of hp to use go light otherwise go heavy, especially if you live/drive in the mountain area.Normal driving we are talking, no idea about the car racing
Lol. So the more weight on the car or wheels will make more acceleration because the more energy storaged? Do you forget that the flywheel must reaccelerated after shifting?
“lightweight flywheel”….. never heard of such a thing…. tell me you hate torque…
I put a lightweight flywheel (7.1kg) on my 231hp BMW M54B30 drift car and I can definitely notice the loss in inertia when trying to initiate drift with a clutch kick or throttling into a drift from mid rpm. The car really needs a lot of rpm now. It’s probably a bit more lively at high rpm but at low and mid rpm it is dead. I don’t like it already. As Google search AI summary says – breaking traction with a lightweight flywheel really is harder and the car feels as if it has less torque even though it doesn’t, it has less inertia. Maybe for 1000hp pro cars it’s fine, but for low powered seat time and grassroots cars the heavier flywheel is just so much easier to drift. I can see the benefit for road racing though, where you’re mostly on throttle at higher rpm and you don’t need inertia to break traction and you do lots of fast downshifts under breaking. But for drifting your 200hp BMW I would suggest you avoid it. Make you car as light as possible, but leave the stock flywheel in.
my experience in a corolla xrs. monkeywrench lightened steel flywheel. revs way faster. improved 1st gear acceleration the most in my opinion, marginally across the other gears. fuel efficiency improved to the point i have 40 more HP over a normal corolla and get better fuel efficiency. i have driven in a major city with 1hr commutes at 20km/h of start and stop and in that scenario it’s very punishing as the car wants to go even in 1st or 2nd at 10 or 20 km/h. It is really hell to be honest but it has trained me to the point i believe i could drive a ferarri without any trouble downtown. I’m going on 12 years on an ACT Street clutch so maybe that helped some of the things i mentioned (recommend those btw). when first installed though I burned the clutch a lot for the first month because you basically have to relearn how to drive a manual. No one but me has been able to drive this car and this includes people who drove manual their whole lives. The being unstealable aspect is a nice benefit i guess. It’s more or less like the video says: if you are driving corners you will love it. anything where you will be shifting it’s funner to drive. If you are in a place where you are stuck in traffic jams, it will be a living hell. I went from 13lb to 8.8lb for the flywheel and i can say the lightened steel has been durable.
