New or Used Flywheel? - The Unofficial BMW M5 Messageboard (m5board.com)

JML M5 · 27th February 2008, 20:33

It is time to replace my clutch and possibly flywheel. I bought the car at 45K miles with a brand new clutch. Now the car has 75K miles. The car has the original flywheel. My independent mechanic suggested that I will likely need a new flywheel due to the length of time I have been driving the car with a slipping clutch. (about 5K miles) He also suggested that I use a low mile flywheel that he took out of an M5 recently to save $$$. The owner of the car upgraded to a lightweight flywheel and left his old flywheel with the mechanic.

He is offering me the used flywheel for $200 as opposed to the much higher cost of a new flywheel...approx $550. I asked him what he would do if it were his car and he said that he would go with the used one as it is in "good" condition. Is it worth the few hundred in savings or should I pay the extra $$$ and go with the new one?

Those who replaced their clutch and did not get a new flywheel please chime in.

Thanks.

The labor cost to replace a flywheel alone would be an indication to go with a new flywheel. I had my clutch replaced and along with it a brand new flywheel. The last thing you want the shop to come back and say is that the "used flywheel" maybe causing any issues you may have after the install.

Given the price difference between new and "used" is only ~$350, I would feel more comfortable going with the new. The price difference is minimal for something like this...

Not reusable.Go with the new.

I have the same opinion-that $350 saved right now won't seem that much when you have to pay the labor to pull everything apart again because of the used flywheel possibly not being up to spec.

Like the other folks I personally would opt for new unless you are somehow able to extract a warranty, in writing, that if the used one fails, or causes other parts to fail, your indy will replace it with a new one for the price difference ($350).

Replacing a used flywheel with a used flywheel is like replacing a used brake disk with a used brake disk. Makes no sense at all.

Phillip at Dinan told me that the stock set up is best.He said their clutch is ok but the stock will last longer. The Dinan flywheel is lighter and allows for quicker revs. Stock motor ,stock clutch.
