I declined to purchase a lightweight flywheel when I replaced my clutch/flywheel with single mass for a few reasons.

Years ago I ran a GT3 spec RX7 that started life with a light weight flywheel and replaced the 12a with another later model version with a heavier flywheel. Although I missed the quick rev nature on downshifts etc I seen exactly zero performance increase on the track, no lap time change or top speed change down the longest straight.

2nd reason is my wife drives this car from time to time and didn’t want her to have to slip the clutch on take offs more than stock.

The gear rattle with the single mass clutch is noisy no doubt but I don’t mind it sitting at stop lights although there will be some that prefer the stock flywheel silence.

I got the Valeo kit and could not be happier with how it performs, except for the rattle you would never know there was a change.
