I recently replaced my clutch/flywheel with a new clutch masters kit. The clutch is a stage 3 and the flywheel was the lightest one I could get for my clutch (I could never find the weight and forgot to weigh it before I put it in).

I have put headers/cold air intake/ racing chip/ a new cam which was a pain in the butt to get in/ full custom cat back exhaust I could get built for me by a local shop. The shop around here does a lot of custom exhausts for about 40% cheaper than you would usually buy the exhaust by itself/ and a few other minor mods

I have to say the clutch and flywheel made way more of a difference than I expected. I kind of wish I did these first since the clutch kit was 88 dollars on ebay and the flywheel was only 130!

I would have never of thought such a easy upgrade would make my car so much more fun to drive!

Btw I have a 91 honda civic DX with major weight reduction to it. The car was 1580 pounds stock with the only luxury being AC. I took out the AC unit/door panels/back seats/ front seats are racing seats/ light weight battery/ a few other little things to reduce weight.

With all the work done to my car its about 180 HP and around 1400 pounds.

I still have to say with all the easy upgrades done the clutch/flywheel was by far the best!

Oh and for those who are wondering how much wind kills my car... its like a cardboard box in a hurricane. When I hit bumps in the road going over 70 MPH I catch air since I don't have any downforce at the moment.
