e30ftw 410 Report post Posted July 29, 2013 (edited) I need a m20 flywheel and have one given to me but I don't know whether it's a single or dual mass (it's not with me yet still need to get it shipped to me), This is the only photo I have can anyone tell from this picture unless i get clearer ones of the other side?? Maybe you can't really tell from the backside, if so I will have to wait for better pictures. Was from a Pre FL 320 As far as I know, as it came from the same car that 240 in the picture is from. Can't find any clear pictures on a m20 dual vs single mass wheel either. Edited July 29, 2013 by e30ftw Quote Share this post Link to post Share on other sites

e30ftw 410 Report post Posted September 1, 2013 (edited) Okay I have one with me now....It's not that one though and this one is 9.4KG.... Can I safely get it taken down to ~6.5KG ? Any experiences too on what the general cost for lightening a wheel? Edited September 1, 2013 by e30ftw Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2132 Report post Posted September 1, 2013 i shaved back side of the outer ring down to the ring gear, and just a very very light surface skim on the rest of it to make it look pretty again. very drivable like that though did have any problems at all, drove the way it should just re-read my build thread looks like i didnt weigh it though sorry.
