So I'd like to hear everyone's opinions on which lightweight flywheel to go with...I currently autocross on occasion, and most of my driving is spirited and/or highway.

Any first hand accounts would be prefferred...
Also, which one's are the lightest? Which ones work best with N/A setups?
Search is great, but there's too many discussions involving parts to get the answers I'm really looking for w/o going through a zillion posts.

Thanks guys!

 

Fedenza makes one also

 

does anyone take their stock flywheel to a machine shop and have it lightened and balanced? I've done this with other cars.. just wondering if its at all popular amount the S2K crowd.

 

Done a little research on this too. Here's the some specs I found:

Comptech - steel - 9.3lb
Spoon - steel - 9.3lb
Toda - steel - 8.7lb
Fedenza - aluminum - 8lb

 

How much does the stock flywheel weigh?

 

I use a Toda and am happy with it, but would think there is little difference to the driver if the weight is about the same.

Machining the stock FW is not recommended, but by the time you got a notable amount of weight off it probably would be too thin and out of spec.
