There's a bit of debate on this topic. According to Sachs, you can leave the Dual Mass Flywheel WITHOUT resurfacing (if it's not damaged) on the first clutch change. Any subsequent clutch changes (on the 2nd and so forth) requires a new FW.

Your thoughts? GO!

I reused mine and wish I had resurfaced or gotten a new fw, it engages a bit uneven/vibrating especially if in reverse.

 

I reused mine and it works perfectly.

 

Perhaps a dumb question but was it inspected? Maybe it had heat spots and uneven/warped spots.

p.s. I believe you have the sachs 2.5 right? How's it holding up with the e85?

I have the Sachs 2.5 and mine is doing great on a Protomotive E85 tune!

 

Yes it was inspected and I guess I should have gone with a new one. It had some minor uneven/spotted patches and it works and holds up fine.

It just isnt perfect

 

How much power are you putting up?

-Jose

 

I put a new one on mine.

 

If you are changing out the clutch anyways, I would seriously consider a light weight aluminum fly wheel. You'll get some chatter at idle, but much faster revs. Well worth the sacrafice. Relatively inexpensive too.

 

I put a 2.5 in my 09 with about 29K at the time. Inspection showed no hot spots or damage so I retained the original flywheel with no problems at all. Regarding light weight flywheels, besides gear rattle clutch engagement can be a little more challenging given it's reduced mass. Certainly helps throttle response though.
