Yes I ordered my flashpro and vit tune already just wanted to know what was the purpose of a lightweight flywheelI don't know about power or anything but make sure you have FP or your car won't run right. I can't find the thread but there was some info on the car not liking the lightweight flywheels for some 8th gen clutch kits.
Hmm I guess what I really want is more power but I think there's not much else I can do other then rbc and rdx swap but I'm going to supercharge my car in the spring so there's no point in doing that for me.A light wt. allows the engine to get it's rpm up faster, and will have less drag on deceleration.
These are not always what I'd call a better change, depends on why you want it.
