I'm considering getting one for my TII. Basically comparing your stock to aluminum flywheel, how different does the car drive? Low RPM cruising impossible, major loss of low end power, etc, anything like that is what I'm worried about.

Thanks,

i have the jun chromoly ultralight flywheel...

it takes a lil bit of getting used to starting...spins much faster, so more abrubt engagement, but you will be able to accel much faster once you get going

What would much faster be? I mean does it take any time off your 1/4 mile time for example?

There is nothing to worry about. I noticed no difference in how the car drives. There was no loss of low-end power, and there was no difference at light-cruise.

I run an 8.5# aluminum flywheel with a solid disk 4-puck disk in *hilly* Atlanta. In ~5000 miles, I have never stalled the car. Only downsides I can think of are:
1) You need to pay more attention when engaging the clutch, and
2) In my case, the copper disk (not the flywheel) does not like to get hot. When it does, it engages even more abruptly than usual - this may, or may not apply in your case.

IMO, this is a good, but expensive mod.

As far as 1/4 mile times go. Conventional wisdom states, keep the stock flywheel, as the light unit will not launch as well - it looses too much momentum at launch where a heavier unit will tend to keep the rotating assembly in motion resulting in a better launch.
