bmw alloys on a corrado

[KADVR6 0]

i have noticed that you can get bmw bbs alloys a lot cheaper than vw bbs alloys. dont know why?? i know you can adaptors for porsche & merc wheels. but what about bmw wheels?? any help is appreciated :D

i think e30 wheels go straigh on chief :wink:

Not onto a Corrado VR6 they won't... VR's are 5 stud :(

 

I think someone has said before that because of the way the offsets work, etc, its not really possible to get adaptors to put newer BMW BBS wheels onto a Corrado.. frustrating as there are some VERY nice and not too expensive examples out there :(

in a local bmw breakers he has a set of bbs rcs 7.5 x 17 with an et of 53. with some 20mm adaptors. if you can get them? would they not fit? he only wants £150 for the set. :(

20mm adaptors will convert the 5x120 stud pattern (if they're 5 stud) to 5x100 and take the offset out to 33, so spot on.

great they are 5 stud. just gotta find some adaptors now :?:

[Kevin Bacon 5]

I think H&R do some 5x120 to 5x100 adaptors. They're not cheap though, £180 a pair!

 

http://www.superlite-wheels.com also do adaptors for various applications.

I never understood all this 5x100 ET35 malarky. It strikes me there's just not enough information to define the size and placing of the wheel bolts there..

Thank god you don't work for BBS then :lol:

ok so the 5 x 100 means you have 5 bolts 100mm apart. but what exactley does the et mean? i have a rough idea but not the exact reason :?

[Musicman 0]

ET is the offset distance in mm between the mounting surface of the wheel and the true centre line of the wheel.

 

Handy diagram to illustrate and a slightly more involved explanation here

Ok, but is that each bolt is 100mm from the next, or are they all placed 100mm from the centre of the wheel?

 

And how BIG are the bolts? Diameter wise. That's not accounted for in these figures at all...

 

I'm pretty sure that if I worked for BBS I'd either learn very quickly or get fired... ;)

 

** Ok i checked out the links, very good.. I now understand PCD and ET. But those figures definitely do not define the diameter or thread pitch of the bolts. That's why it never made sense to me.. :)

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.

 

Zero Offset

 

The hub mounting surface is even with the centerline of the wheel.

 

Positive

 

The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.

 

Negative

 

The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.

 

If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly.

 

See this site for further details / diagrams,

Think FK do some BMW to VW adaptors - Speak to the guys at Gwent VW, they should be able to help

Five studs are measured by twice the distance from one stud to the centre of the hub hole.

thus giving you the pitch circle diameter of the studs. if you measure stud to stud on a five stud you will not get the pcd.

 

four stud is easier you can just measure stud to stud for the pcd as they are opposite each other.

 

by the way a 53 offset on a bm sounds a little odd. which model were they off??

if they are off a five or seven series it is more likely to be 23, if they are of a 3 series it is more likely to be 33. just worth taking a closer look.

can i convert 5x112 to 4x100 for my g60 from a bmw wheel????????

ET 53 are you sure, beemers usually have a lower offset than that. :roll:

thats a porker sort of offset :wink:

have spoken to the guy with the alloys they have an et of53, thay were of a 328 2001 model, but he says they are not at all standard equipment. will go in person on thursday 2 see if he is number dyslexic, cheers guys :D
