I recently installed a spec stage 3 clutch kit along with a jbr aluminum flywheel , everything ran fine for about 200 or so miles until I was started having trouble getting into gear , there was a lot of resistance and eventually it didn’t get into gear at all , I thought it was going to be my throw out bearing but when I dropped my transmission the other day this is what I found , the slave cylinder was broken along with the pressure plate ( springs unpacked ) but my throw out bearing was still intact , I have warranty on my clutch so I’m sending it back but here’s my next concern , does my flywheel also need anything done or is it still good ?

You could probably keep running it it, but now that it's apart, you should probably refresh it. That thing looks like it got pretty hotsigpic

Taking a transmission off is a pain in the ass. Any time I'm in there I replace what might need it. That looks like it's resurfaceable, but if not it's a replaceable steel plate so I'd do it.Comment

Call JB first and ask. I just sent that same flywheel in to JB to be refreshed because it was out of the car, like yours, and they refused to put a new plate on it and shipped it back.Comment

Huh, so the consensus is to not use them? Why did you guys go with their light flywheel instead of turning a stock one?
I've just got an lightened regular flywheel, which I've been happy with. I think I'm around 8 lbs?sigpic

I liked the idea of the replaceable hardened plate on the JB, but that isn't much good if you can't pay to replace it. On Linda I used the RHD chromoly flywheel which was great, and on Hoopty I used a lightened stock flywheel which has also been great. The light factory early 528e e28 flywheels are also a solid option if you can find one.
I wouldn't use JB again due to the aforementioned. I would use RHD again. I think a lightened stock flywheel is best, though, if you have access to a machine shop familiar with lightening/balancing them.Comment

I replaced the JBR with a RHD Chromoly flywheel. I've been happy with it.AWD > RWDComment

I'd probably resurface it in the hopes of not pulling the gearbox again for a while.Comment

I've had good luck with RHD. Used the same flywheel with a couple different transmission and clutch combos.
Always get great email communication with Rama, even years after buying the flywheel.
Not to mention the 7.5lb flywheel is light as heck and makes the engine happy to rev!
