I have a 2008 R56 S. I am looking at getting some new 16/7 wheels with 40mm offset. I'm sticking with 16" since I have just purchased new 195/55R16 tires within the last year.

I'm currently running stock suspension but plan on upgrading to bilstein pss10 sometime in the future, which will lower me about 30mm I believe.

Will 40mm offset be okay or should I look for different wheels, if so what offset should I look for?

Also the wheels I'm looking at come in two versions. The only difference seems to be in the bolt pattern... what is the difference between 4-100.00/114.30 and 4-100.00/108.00? Will either work or neither? I'm guessing that just means the bolts could be either of the 2 distances apart.

Thanks

 

I have 16x7 with 205/50/16 at 42mm offset. 12mm spacer in rear and 8mm spacers in front. Giving me 30mm offset rear and 34mm offset front. I m lowered on KW V3 with all four wheels tucked. Zero rubs and I think i can go even lower offset, but I m not taking the chance its getting quite close.

To answer your question yes you should be fine with everything you want to do. As for rims as long as its hub centric 56.2mm and 4x100 bolt pattern you are fine. Make sure you get longer lug nuts (14x1.25 tapered) with correct thread as you are going from stock 48mm offset to whatever lower offset you going to go.

 

OK, stock MINI 16x6.5" wheels come with ET48 offset.
Last year, I ran 225/50-16 RS3's (at least 10mm wider than labelled) tires on stock wheels with KWv3 suspension. Suspension was set as high as it goes, which is ~2.5" drop.
The front tires were barely rubbing on the inside on the strut tower (fixed with 5mm spacers), and rears on the outside on the fender liners (no remedy, wheel well liners took the hit). But that was with more than 30mm wider tires than yours.

You should be fine, but I would err on the side of going with larger offset wheels for rear fender clearance.
Remember, you can always erase larger offset with spacers, but there is nothing you can do to bring wheels back towards the centerline of the car if you are rubbing on the outside of the fenders with too little offset.

Interesting - your tires were effectively 10mm closer to centerline in the back, yet even with 12mm spacers on top of 6mm smaller offset, you did not rub (net 6mm closer to the outside of the rear fender than my 225mm RS3's were supposed to be, if you trust Hankook width measurements ).
I guarantee it that you did not run RS3's ;-).

4x100 is the MINI wheel hub's bolt spacing diameter.
Anything different will not line up.

What mcc21 said on center bore.

If you are using spacers, you can correct for wrong wheel bore with more expensive hub-centric spacers. Spacers == longer lug bolts. Else you will be loosing lug bolts, then wheels. Wont be pleasant.

If aiming for no-spacers (way easier and quicker when swapping wheels on and off), 2x check that you are getting 56.2mm (*pretty rare*) MINI bore, else you will never get rid of the wheel vibrations.
