wheel spacers

just got my set of new Fuchs replicas, Euromeisters of course, seems a new shipment has hit the country.
The fronts are 16x7 rears are 16x9.
The wheels Im replacing are a set of pretty beat up BBS in the same size but it appears the offset is slightly different.
Wondering from the Fuchs crowd out there what front and rear spacers are
recommended. I have test mounted the rims and it appears the fronts need
mabye an extra inch of spacer?
It looks like the rears have too much spacer and I will be close to having a
tire rub issue. The current spacer on the rear is 30mm.
next question is do I need to replace the wheel studs as well and if so
what length is reqired front and rear.
I will need to order new lug nuts as well since the existing ones are hollow and
will not look right.
Thsnkd in advance....

Not a clue on the spacers, but if by hollow lug nuts you mean open ended, put the spacers you want and put the open nuts on, if you get full engagement with a couple of threads showing you're fine, get a set of oem closed lug nuts and go.

What are the offsets on the rims coming off.

They should be stamp inside somewhere.

If you can not find them, put the old rims back, put a straight edge vertically on them and measure the open space to the body. Repeat with the new rims and measure the same gap. It will give you the difference position wise so you'll know what more you need in front and less you need in the back.

The measurement has to be taken with the car weight on the wheels.

As for the lug nut, how far are the studs sticking out on the new rims?

OK,
I think I'm getting this figured out, the fronts I need about a 1" spacer and I know I can put in the proper length wheel studs into the spacers.
The rears however need a 20mm spacer. This will make my wheel studs too long.
Especially if I use "acorn" style wheel studs to match the black centers of the wheels. Do I need to replace the studs or is it ok to shorten the exisiting ones?
If I replace, it looks to be a bit of a bigger project than I expected.
Any Ideas???

Just use open end lug nuts.
What are the ET on those wheels?

offsets are 23.3 fronts and and 15 rears,
Rarly 8 the 16x9 wheels are now in stock at Automotion...
I do not want to use open ended lugnuts for cosmetic reasons.
Thats why I'm asking about the length of the wheel studs.
Thanks everyone for all the replies so far.

Not knowing what car you are referring to makes it hard to answer your questions, but for a stock 1979 930 turbo:
Front rims Fuchs 16x7 with 22mm spacer
Rear rims Fuchs 16x8 stock, but Fuchs 16x9 with 15mm offset will fit with 28mm spacer

BTW, there are charts out on the forums with stock offsets for Fuchs rims.

Car is an 84 Euro 930,
It appears there is about 30mm spacer on rear and I'm a bit concerened about clearance.
There is about an inch offset difference between the BBS wheels I'm removing and the 16 x 9Replica Fuchs I'm installing. ( need to go with a thinner spacer on the rear to prevent tire rub. Wondering if a 15 mm spacer will be enough for brake caliper clearance. This is on the rear end.
The fronts I have about an inch offset difference between the BBS removal wheels and the
16 x 7 replica Fuchs. Here I need to add thickness for proper stance.
Not having installed spacers before is there a recommended brand?
Thks in advance again...

Make sure to get hubcentric spacers, meaning ones that support the center bore of the rim.
Also, make sure to get full circle spacers, not ones that look like a 5 pointed star. They will likely not hold flatness as well as fully round spacers. I cannot tell you a brand since I use the OEM on my turbo.

I too just got a set but mine are in 17" I'm just waiting on the tires. I'm installing them on a 85 Euro 930. I hope I wont need to mess around with new spacers.

While I think spacers are fine, I would lengthen the lugs to go through the new inch spacers and not purchase spacers with the lugs integral to them. My .02 cents. Maybe others can give their opinions.

No, I'm waiting on Toyo Proxes Sports. The shop I use has two fronts and only one rear. I will find out tomorrow if they can get me one more rear.

Could never figure it out how they (tire shop) end-up with one tire...

If you break the last pair, find one before someone need a pair
