so is buying an aftermarket flywheel really worth it, and does it affect interstate speeds.....im lookin at an aluminum flywheel b/c i will be doin my clutch in a few weeks so im tryin to get the lowdown. what do yall think should i spend the extra money or not.

Stick with steel if you want easy highway driving. A lighter flywheel will help acceleration very little, but will have a very noticable affect on driving on the highway and taking off from a stop. Your car uses the flywheel's stored energy to help you take off from a stop and moderate accelerations while on the highway.

now wait i thought a lightweight flywheel helps acceleration.....why would it hurt highway speeds, if the crank is already turnin why would it need a heavier flywheel to keep up momentum?????? heres the thing if it will make a GOOD difference then i will fork over the cheese and be happy if not then i will just get mine resurfaced.

i have an aluminum flywheel... i noticed on the butt dyno it was little quicker but doesnt mean it did anything[8D]

how much does the new flywheel weigh compared to the stock one.

rbstang

i think mine is 13 lbs... i think the stock one is in the 20s... maybe 25-28? idk though.

rbstang

lol I notice every single bolt-on I do, and right now my car feels worlds faster than it was stock. Huge difference even before gears!
