Ruff Wrong bolt pattern!
Ok I was really leaning toward the ruff 278 in chrome, but reading some post about how they are the wrong bolt pattern I am now hesitant to buy them. I do not want to deal with any kind of vibration or risk of loosing a wheel, because I run at high speed on a regular basis.
Can anyone send me in the direction of a wheel that is similiar to the chrome ruff 278 they will fit correctly? Thanks, Brett

So why do some people state that using this wheel will cause problems? The ruff is a 5x4.72 and camaro is a 5x4.75. Im really leaning toward this wheel. I just need more people chiming in here with there experience with ruff fitment. Thanks, Brett

It's a 5-120mm bolt pattern compared to 5-4.75"
4.75" = 120.65mm.
It's a .65mm difference. In other words, lots of people use them and I've yet to see a problem. In fact alot of the aftermarket wheels (non replicas) are 5-120 because it's a more common (Euro) bolt pattern.

0.65mm isn't a big deal. Especially when divided in half, since you are spreading that tolerance over the outer diameter of a circle. That means if you are centered up, the lugs are approx 0.325mm off. The tolerance on lug studs themselves isn't even that precise. Pull out a ruler and see how small 1/3 of a mm is.
In other words, 1000s of people are running 5x120 wheels on a 5x4.75 lug, and I haven't seen any issues yet. You are more likely to have problems if you don't use a torque wrench each and every time you install a wheel.

It's called a "hubcentric" ring, and it's purpose is to fill the gap between your car's hub OD, the the wheel's centerbore ID. It adds support to the assembly, so the studs aren't the only thing absorbing the load. They do not space out the wheel. There usually is a "relief" or taper on the backside of a wheel's centerbore, and the hubcentric ring's flange fits in there.
OE wheels are "hubcentric" so the rings aren't needed. Aftermarket wheels are frequently "universal fit", and have a large centerbore to accomodate many different car's hubs.
Most shops that sell aftermarket wheels also sell the rings, but if not, you can do a Google search, and a few sources will be found.

I'm running 5-120mm RPM 505s. I have 72.62mm-70.30mm hub rings but I'm no longer running them, no vibration so far. I just make sure I torque the wheels in intervals when installing and recheck ever so often.
Here's the hubcentric rings. Not sure what size you would need for the Ruff's but the hubs are 70.30mm.
