I recently purchased and mounted a set of BBS RX204 with an offset of ET38, 8x17 all around. I noticed when installing them, that they didn't slip onto the hub lip as tightly/snug as the OE wheels (DS2s). There was a little bit of play causing me to have to move the wheel around slightly to get the lug bolt holes to line up.
I didn't think much of it at the time, but of course now when I'm around 60mph I feel the steering wheel shaking a bit. I'm confident it's not the balancing as my father and I mounted and balanced the tires ourselves at his shop.
My question is this: Does anyone know the inner diameter (center bore?) of the BBS RX204 wheels and/or what size rings to get for my hub and/or wheels?
-Thanks.
There were only 2 sizes of hubs, 74.1 and 72.56. I believe the only car with the 74.1 was the 5 series e39, all the rest had 72.56. If its a newer wheel, probably the bigger. Go to Discount Tire, or any well knowm dealer and buy a set, about $10. Or Ebay has them galore. You'ed be surprised how thin they are but it will cure your shimmy.
Lets get the party started before it's my bedtime.
I didn't get a chance to measure the wheel last night, but I will do so tonight just to confirm.
After speaking with BBS yesterday and the gentleman who sold me the wheels, it sounds like it's most likely a 74.1 bore after all. I just ordered a set of 74.1 to 72.56 rings on Amazon last night - should be here tomorrow. Worst case I'm out $15 for now and will have to figure out what to do next later on.
Just measured the hub and wheels' bore. Rings are exactly what I need and they're coming in tomorrow.
