Clutch & Flywheel advice please

bcfromfl · 04-14-2018, 05:12 PM

I tried calling ZSpeed today (Saturday) but didn't get any answer -- I'll try again next week.

I've decided to go with the Stage 3 South Bend clutch kit with CMAK and quiet disk, but don't have a clue which flywheel to select. I'll never track the car...it's basically just a fun toy to drive when the weather's nice. I'll need the Stage 3 to hold Topz's A2A kit. I don't like how the OEM flywheel "overshoots" revs when shifting in higher RPMs, but I appreciate how it contributes to a civilized drivetrain.

Where I drive are some stoplights/stop signs, and I really don't want to negatively affect the driveability of the car. I've read how touchy light flywheels can be, but I'm frustrated that the only choice at ZSpeed in the mid-20lb range is a nodular iron flywheel. On other cars, nodular iron doesn't get very good reviews.

I'd appreciate thoughts on the nodular iron flywheel vs. the 19lb DXD billet one, or other suggestions. Once I'm Ecutek-tuned with the supercharger, might the factory flywheel be an acceptable option?
