Extended Lug Bolt lengths?

F82_SID · 09-22-2014, 12:13 PM

Hello all. I am trying to re-install the Mach Schnell spacers from my E92 M3 onto my M4 but need to figure out the correct extended lug bolt sizes that I need to order.

I know the specs are 14x1.25mm but I dont know what length to order for 15mm spacers up front and 12mm in the rear. Can anybody help?

Are all the stock bolts the same length? If so, what length are they?

Both are going to be a 40mm length 14x1.25 thread pitch. I have them in stock, ready to ship as well.

Is the 40mm the length of the threaded part or the whole bolt? I guess 40mm is the same for 12 and 15mm?

Thanks.

Correct 15 and 12 use the same size wheel bolt. 40mm is going to be the threaded portion.
