F1 Racing Chromoly Flywheel Has anyone ever used one of these or heard of someone using one. I seen it on ebay. It seems like a really decent price but I'm concerned it could be a cheap piece of equipment. Thanks for any imput on this.

It says it is
Ultra heavy-duty and weighs only 15.45 lbs (Stock flywheel weighs 24 lbs)
Meets or exceeds SFI 1.1 specification
Made from 100% 4140 chromoly steel (2X stronger than Billet Steel)
F1 Racing Lightweight Chromoly flywheels incorporate special design features to enhance the airflow for improved clutch cooling
F1 Racing Lightweight Chromoly flywheels work with every clutch including Exedy, ACT, Fidanza, Clutchmasters, and other OEM clutch kits
CAD designed, CNC machined and computer balanced
Sure sounds tempting

It sounds like a nice product. I guess I might have to be the test rat. I'm just not sure if I need to be going that light as my bottem end power sucks already.
Slvrhwk- I like that speed limit sign in your sig, nice touch

any updates? the findanza aluminum ones warp bad sometimes, because of the two different types of metal heating and cooling at different rates, if this F1 works, could be really interesting, i put one on a honda crx and it seemed like a really good piece and made a big difference in reving

Chromoly sounds like a good material in theory...though as mentioned above it can be considerably more brittle than a Billet Steel or Billet Aluminum flywheel. The other thing to remember is that this material has a tendency to warp in high heat applications.
Someone referenced the tendency for Fidanza wheels which use a steel insert (similar to ours) to warp. We use inserts on a number of applications (all of our aluminum and even some of our steel) and even in the worst case scenerio with the most heat all you will have to do is replace a friction surface. That can't be said for a chromoly flywheel which, when heated, will warp the entire unit. Many times in an attempt to bring weight down these chromoly flywheels are cut very thin which can lead to a greater potential for warpage all together.
I know some of you will think I am trying to push our product by talking down another...but this is not the case at all. Though I have not personally inspected this specific product I am speaking from experience in regards to other similar units that we have inspected over the years. I just want you all to know what to expect when using a flywheel made of this material. To be honest, if it were a good as it seemed, we would be making these ourselves. Let me knkow if you all have any further questions. Thanks!!!

I have an SLP flywheel also. The guy at SLP said it weighs 8 lbs. lighter than stock. He said a stock one weighs 28 lbs so that makes this one weigh 20 lbs. I could tell a difference in acceleration too. He said the SLP clutch is a 2002 ZO6, I'm wondering if the flywheel is a 2002 ZO6 also.

I've got one of these flywheels and a SPEC 3+ clutch and am having issues with engagement. I know the trans and master and slave are good. I've measured and used the shim and it shifts super notchy. I'm at the point where I know its either the clutch or the flywheel and am about to dump them both for a new combo. Does anyone have any thoughts?
