yeah the comptech made a nice difference. I've had it for well over a year.
The comptech and all other fw's were made with street driveablity in mind. I don't drive my car on the street anymore and would like the additional throttle response of a lighter fw.
Pullies are on the list too.

I'm a huge fan of reducing rotational mass also. In fact, my S2000 probably has less rotating engine mass than any other.
Anyone remember the company OLM-R? They use to make Honda parts for racing and offered a magnesium flywheel with a titanium face that was about 4 pounds. I don't know if they ever made them but they had it in their catalog. Magnesium would be the ultimate choice for this application but the titanium can cause lots of issues as a friction surface. While testing titanium rotors, I found that galling becomes a huge issue with every pad compound tried. There are companies that can plasma coat a titanium rotor/flywheel with a ceramic coating that won't gall and supposedly lasts forever. One company that does this for professional motorsports is called Red Devil...?
Krazik, your distrust of aluminum flywheels is warranted, however, some are now using aircraft through bolts with aircraft lock nuts so it is very unlikely that any separation would occur. No more threading into aluminum.

its the mixing metals that worries me the most. Different metals expand at different rates and thats why AL flywheels like to come apart. They all have a steel face, some of the shadiest ones just rivet it on.

Rylan, 7-8 lbs is a good weight for a flywheel. Trying to save another lbs or two there isn't worth it for the time/effort/cost involved. What you should look at is the clutch. If you're willing to spend the dollars, a dual/triple disk 5" carbon-carbon clutch would be perfect. Great engagement, less mass and a much smaller MoI due to the reduction in diameter.
Some machining would be probably be required on the bellhousing for fitment, but these are the best. Near F1 technology in many cases. Tilton is already doing them for FWD Honda applications. You'll be looking at $2000+, but it should last a whole season, never slip and improve transient rpm response.
