wheel bolts for E92

N8N · 09-22-2012, 07:49 AM

questions:

1) is there any issue using wheel bolts *longer* than required for your application on an E92? How much longer is acceptable? (I have a set of bolts for 18mm spacers but am thinking I should be running closer to 12.5s)

2) Are the lug seats on the stock wheels tapered (conical) or spherical?

Am asking because I'm getting ready to test fit my winter wheels and tires which are aftermarket wheels with tapered seat lug holes. I haven't been able to pull a stock wheel yet because apparently I need a lower profile jack :/ Also had an experience with an old VW where I trashed one of my rear brake assy's because I didn't think; was running aftermarket alloy wheels and was using a stock steel wheel as a spare, got a flat one night - the longer lugs protruding through the brake drum with the spare mounted on the rear hit the strut thing for the parking brake. Whoops. After that I kept four short lug bolts in the trunk as well.

If you stay with a 12mm spacer your best bet would invest in a stud conversion with open end lugnuts. 75mm studs will work for 12mm spacers safely, anything more would need a 95mm stud kit. Pm me if you want a titanium 75mm stud/kit for a great price, super strong and light and corrosion free. There are other steel stud kits avail from vendor on here as well.

don't really wanna do studs because I still have the stock wheels for summer which work with no spacers. But those are some nice looking parts. I assume from the pics then that the seats are in fact typically tapered/conical on a Bimmer and that my ASSumption that they were spherical is just a mental leftover from my days of owning VeeDubs?

cool, thank you! one less thing to worry about. Saw the tapered seats on the wheels as I was cleaning them up last night and thought it might be a problem. Now off to buy a low profile jack...
