Bit of a daft question

[LeeLee]

But I'm fitting bbs rm wheels to my e21 and I need spacers so was wondering if I should fit new wheel bolts to as less thread will be in the hub,or can I use the bolts on my car I'm probably gonna have to fit a 10 mm spacer
Cheers

Also does quality of spacers really mater there's a load of no named ones on ebay

You will need longer bolts.

Buy hub centric spacers alloy ones!

[LeeLee]

Ok cool yeah that's the plan need to know sizes and dimensions to order from superforma

[LeeLee]

What size wheel bolts do I have? I'm fitting 10 mm spacers,I'm trying to order on superforma and it's asking me loads of questions I don't know the answers to,
Wheel Bolt Seat? Fixed 60 deg taper? Or fixed radius?
Stud length? 27 but with 10 mm spacer 37 but the options are 35 or 40? Which should I go with? Would 39 be to long?

[nas80]

What size wheel bolts do I have? - they are m12 x 1.5
Wheel Bolt Seat? Fixed 60 deg taper? Or fixed radius? - 60 degree is standard, Unless your chosen wheels uses odd bolts or studs you want a 60 degree taper,
Stud length? 27 but with 10 mm spacer 37 but the options are 35 or 39? go for 39mm.

Ok il get the longer ones I'm fitting bbs rm's at the moment I've got standard e21 steel wheels with standard bolts,I thought they are ball/radius looking at a pic of them,but you think there the 60 degree ones?

[nas80]

sorry I mean the cone style seating bolts, like your original bolts are. lol they are also called cone, taper and all sorts of other names, still the same bolt, its got a sloping seat.

just look at your wheels man, have they got a slope or a ball shape? don't blame me if you start ordering the wrong ones!

[LeeLee]

No I won't haha I was just wondering what the terms mean as I've never ordered bolts online just In person so don't know the names there just like the e21 ones the profile is the same only shorter and I don't know what there called out of the two options on the site

[nas80]

I ordered spacers and bolts a couple of years ago, that stuff is expensive and I had a set of RMs and used the cone style seat. I think only wheels that are for porsches come with the ball type seat?

I went for these ones really happy with them very light as well

Nas,
What wheels are you running? I've got some 15'' Mahles to pop on.
I've got 30mm bolts on my Mims, considering buying longer bolts to run the Mahles, Alpinas etc if i ever find them.

What size wheel bolts do I have? - they are m12 x 1.5
Wheel Bolt Seat? Fixed 60 deg taper? Or fixed radius? - 60 degree is standard, Unless your chosen wheels uses odd bolts or studs you want a 60 degree taper,
Stud length? 27 but with 10 mm spacer 37 but the options are 35 or 39? go for 39mm.

Forgot to ask the question....
What is everybody's recommendation? 30 mm, 35? 39? Is it over kill if all i will ever have on the e21 is Mahles or Alpinas(one day.)
