i just got some new mandrus wheels and they didn't send the lugbolts. Am I okay using the stock lugbolts?

thanks

Do NOT use your stock lugs. I had read one member use the stock lugs with those Mandrus and it turned out the stock lugs destroyed the emergency brake. I belive you need a new set of lugs. You can ask the store where you get your wheels.

Good luck

yeah, i read that one or else i wouldn't have even asked. Never had a car with lugbolts before. I would have assumed that the stock ones would work. thanks for the reply

pull your stock rims. drop in the stock lug bolt and measure how much the
threaded portion extends beyond the hub surface. that's the maximum the
bolt should extend if used in your new rims.

you can also bolt on new rims using stock bolts....but (!).... rotate the rim
and listen/feel for any bolt contact with brake parts. some folks have not
tested and simply bolted and drove off, shredding their brake system.

be clear that many aftermarket rims eschew the ball seat design and may
either be different ball size/radius....or may be using conical seat bolts.
the rim manuf should have been consulted and provided you with the
proper sized bolts.

you didnt specific which car you are attempting to put rims on, so simply
guessing.....

Thanks raymond, I test fit one wheel on my 07 c230 and hand tightened and they were still way loose. on the stock wheels i can only see threads on the back side, on the manrus the non threaded part extends about 2 or 3 mm beyond.

be *very* careful at this point. one the surface, it sounds as if the bolts
are bottoming out after youv'e cinched them down. it also appears that
the cross section of the new wheel (at the lug point) is *thinner* than
your stock wheels.

still hard to be precise but there are now TWO red flags. dont even think of
using your current lug bolts. you need someone with experience to help
determine the exact size needed. each of these needs a clear and concise
answer, vis-a-vis new Mandrus rims matched to your 07 C230.:

___ lug bolt length (shank)
___ lug bolt diameter
___ ball seat or cone seat
___ ball seat radius

go back to 203 forum and search "Mandrus". read threads...learn from others'
mistakes...and successes
