Lightweight Flywheel Issues, Anyone else have these? Options

[Coomer]

Hi,
Since I've gotten the car back, I've begun to hate my lightweight flywheel. I'm thinking that now my next modification will be a stock AE86 flywheel.

The main problem I have with the flywheel is the fact that the engine and entire car shudders horribly whenever the engine sees below 1,600 RPM or so and the car is in gear. Whether I'm starting from a stop, or driving really slow in a parking lot, the car will shudder horribly if it sees low RPMs. When starting from a stop, I have to rev the car all the way up to at least 1,600 RPM or so...it feels like I'm slipping the clutch, and that's why it's so hard to get used to. I always want to give it less gas, but then the car shudders so badly.

Also, this makes it near impossible to start quickly from a start without spinning the tires. Whenever I try, the engine simply bogs down and shakes when I try to start quickly from a stop.

Does anyone else have this problem with their lightweight flywheel?

Coomer,

What you describe is perfectly normal. You won't hurt the clutch any by slipping it off the line, thats how it was designed to be used. If you think thats a pain, you should try driving one of our world challenge cars in traffic (in the pits, not on the street, I would never do that, heh heh heh). They have like 6lb flywheels, lightened crank/rods/pistons (only slightly as per the VTS) and a 5.5" triple plate clutch. They idle at like 1400rpm and you can't get them moving without stalling them below about 3000. The clutch is almost totally an on off switch.

As far as launching your car, a little bit of wheel spin is good. On a street tire you're looking for about 15% slip off the line for the best launch.
