Thread: Lightweight vs stock flywheel; momentum

@Viprdude I must have meant a flywheel with no weight, so I understand that would still give a working car.

Personally I investigated a lot about lighter flywheels and came across statements from users that contradict each other.

Also, it is no fun to re-remove the tranny, getting new tranny fluid while what was just put in has no mileage on it and/ or getting the car aligned also twice in a row.

But I believe I understand enough now to make this step. A friend of mine wants to buy my super heavy OZ 17" rims I sell because of the ridiculous weight (it are 1998 Volcano's) and since he is also no show, all go, I asked why. His <800kg car is nervous at cruising speed since his flywheel is too light he told me.

If that is true, caution is relevant. Also the whole issue with low quality, best quality flywheels and broken flywheels, owners experiences with different setups and me not understanding why a flywheel has weight (maybe cheap to cast the iron?) and yeah, I forgot, the flywheel is used also in the drive train.

so dont get new fluid. seriously though, i've had to remove my tranny a few times recently to solve clutch issues and as long as you use a clean container and cover it, you can reuse tranny oil.

I see more positives than negatives in a lightweight flywheel but personnaly want to go with a sr16 flywheel for a happy medium. One negative that could occur would be if you had a LARGE turbo and shifted slow. That could make you drop out of boost with an light flywheel.

@Wingman, true, sadly I have killed the drainplug a tiny bit... Stupid square thing, *no tool available, overhere, really and it is really really stuck.

I'll try getting the tranny oil from a friend who buys in bulk... Then if it is all ok, back to MT-90

I like the stock flywheel, it absorbs the A/C kicking in better. Though, I drive also an 80HP '85 RX7 as well and that thing is all about loading the flywheel. 11lbs wasn't bad on my VE'd g20.
