Cool. What torque spec did you use and blue or red loctite?

Old thread - I know...

Nurburgring - you mentioned you were going to clear the lips. Did you?

Needless to say, they look incredible!

Here's how they look with stock BBS paint color on the centers - next step is to media blast them & repaint with a darker gray.

ymmv and I don't want to be negative, but fyi, I did this and promoted doing so but found I could not get the reverse mounted wheels to balance very well. It may be that I did not get the wheel centers to be centered properly when reverse mounted (the centers do seem to fit better when put together as intended). At regular speeds it was acceptable but at 120-140+ km/h speeds it was very noticeable and did put the wheels back to regular configuration and used spacers. In regular configuration the wheels balanced no problem.

Were you getting vibration?

I had a shop properly reverse mount my LMs (Nubrite) from the beginning, they recommended this was not something you would do at home, I recall something along the lines of the bolt sequence, equipment etc.

So far I've had 2 different set of tires mounted on them, no issues at all to date including speeds much above 140km/hr. I know TripleG had his former set done at Panthers, no complaints too. Maybe something to consider if you want to try again next time.

I think you are right, it is more difficult to center the wheel center when reverse mounted, where as when put together the normal way, the lips in the wheel center are made to fit into the barrel without any play. This also means that forces are transmitted more to the bolts when reverse mounted as the wheel center is not directly supported by the wheel barrel. I decided it was easy just to use spacers in the end. I can't use the wheels anyways now due to my brakes, they are sitting looking pretty in my den (and no they are not for sale before someone pm's me and asks) .

I wouldn't be too concerned about this. There are many 3pc wheels that are set up like reverse-mount LM's. BBS RS's for instance are this way from the factory.

I reverse mounted my LM's myself using the diagonal torquing method and haven't had any issues in the 4 years since. No vibrations at any speed that I've had the car at so far.

I can't use these (or my 4 other sets of 18" wheels), but have decided to keep them as I may get another car in the future - the LMs are particularly a good keeper as I could use them on a narrow or wide body (with spacers).

Anyone have pictures of 18" reverse mount on a narrow body car?
