Nobody knows of a decent light weight steel/chromoly flywheel? I looked at the EBAY ones, but can''t bring myself to use it even though it has had a few good reviews. Car will be int he 600-800whp range so. The ebay one has the ring gear teeth machined into the metal rather than a pressed on hardened gear. Seems a little iffy.

I thought I noticed you had the RXT from some searches and the chromoly flywheel in others 
Have you had the flywheel long and ever inspected it? Did the flywheel come with the dowel pins or bolts? I'm sure from the looks of the car it's seen quite a bit of 1/4 mile track time also.

I put the clutch/flywheel in last spring and probably only have less than 1000 street miles and ~20 passes on it. Have not removed it for inspection and barring any problems this season, probably won't until next winter. The flywheel came with dowels, no bolts.

I did see this I think when searching. Care to measure the inside of the disks and flywheel just for reference? Might help others in future searches, etc. I'm more curious to see the relibility of the chromoly flywheel and if there is any warping issues with it, etc. If I remember what Billy from Mcleod told me on the phone the opening in the center of the flywheel needs to be 6.25" or smaller to hit all of the disk. I know a Spec flywheel is right at 6.25" so I'll probably just run that if I don't go with a lightweight one.

By chance I was at the machine shop today and someone had this same flywheel with the engine parts they brought in. Flywheel looked nice, but it seems like the friction surface is not quite level with the outer ring where you bolt the pressure plate. I would think this could cause disengagement issues, but you guys seem to not have any. Looks like you would have to take .005" or so off the entire surface to make the entire face of the flywheel flat all the way out to the end where the bolt holes are for the pressure plate..
When you bolt the RXT's adaptor plate on it seems like it wouldn't be quite flat.

that quote is talking about the ID of the flywheel, were the flywheel bolts go. The ID of the RXT disc is smaller then that hole so the disc overhangs the inside of the flywheel

If you had a step on the clutch face, that would be a problem. Was it a new machined surface, or was it used and were were felling the slight step were the disc OD doesn't contact. That will wear a small step on a met. disc.

Well I know it will wear into the flywheel over time, but what I'm saying is the ebay flywheel's friction surface is slightly TALLER than the outer ring where the pressure plate bolts on. If you look at the pictures on ebay, etc. you can see that the outer ring area of the flywheel looks like a darker color compared to where the disk will ride. The area where the disk will ride is just slightly elevated if you know what I mean. If you put a stright edge across the flywheel when new it would rest on the friction surface and not touch the outer ring where the pressure plate bolts go. (out by the holes they cut into it for weight reduction)
The disk will overhang just about a 1/8" in the center as stated above on this flywheel. I just don't like how it's not flat all the way across the flywheel.

Yea I think not I was just looking for a suitable lightweight flywheel that isn't aluminum. Not much out there in steel that I could find. I'll probably just run the spec one as it's ~6.25" inside (should hit all of the disk), friend stocks it and I know it's flat/well made (had one before).
