Hey there guys, just wanted to ask everyone what their experiences are with the two companies light flywheel kits. I know JHM has has theirs for sale for quite a while and their price is actually slightly higher than ecs tunings kit ($200 difference). My first issue is they don't actually state what the weight of their kit is, and only say "When compared to the OEM 4.2L V8 Flywheel the JHM unit weighs 7 to 10 lbs less". I understand that its because they weighed a bunch of OEM flywheels are there was variance in weight but an actual weight of what their kit is would be nice. ECS on the other hand clearly states their kit weights 18.3lbs.

Secondly I wanted to ask everyone if they've run the two kits and how they like the improvement/result. Any feedback is appreciated [:)]
