I have both versions - so I'll check mine tonight!

But from memory, yes one does have the ridge and the other just a line. Although from memory I don't think it was that pronounced.

Given the amount of balance weight on that wheel, I am guessing that it might be a replica? Or a really bad tyre!

I've seen wheels with more to be honest mate, my mate has done tyre fitting and wheel balancing for many years and sometimes it's just the way it goes, I had straight out of the box brand new wheels on cars in the past and even they didn't balance up without a lot of weight, I'm personally not worried and don't think it's that excessive as it felt fine at vey high speed and I don't get any vibrations

Now some people have put the part numbers up I'll have to whip the back wheels off next weekend again and check them against the wheels, see what's what!

P.s. It doesn't want to be a fucking replica, I'll go up the fucking wall!

My RC341 has the ridge his just seems to have a line in the paint that makes it look even deeper, so guess its just the pics that make it more pronounced.

There are Reps out now that have the outer stamps around the lugs, just not sure what exactly they say (dont know if they also have the inner stamps though).

Although from the spoke design I think you can still see they are reps.

Yeah it is a V shape, it's the camera and light casting a shadow that makes it looks like a full on groove which it isn't

This weekend is the next chance I'll get with some decent light to have a look so will have to wait till then but will have both rear wheels off again and check the part numbers as you've posted above it'll even give me another chance to clean them again!

Okay went home last night and checked on me wheels ...

The newer spec wheels have the deep ridge and the older spec wheels have just a line (exactly like the photos you've posted)

So yours is normal. Somebody must have replaced one single rear wheel during the life of that car - no biggie

As for wheel weights - anyone that tells you that they can tell if a rear wheel drive car rear wheel is out of balance is lying ... there's no way you'd feel anything.

I drove on a BBS rear wheel that was buckled and out of balance like no tomorrow and I never noticed a thing ...

Thanks mate, appreciate it, if it is genuine then that's pleasing for a start, just wonder why it has been replaced...

Is it true they are part Magnesium? I did wonder if that's the case then perhaps one was place as it may have been badly cracked!

I have had a chat with my mate and am going to pop in and see him this week just as a matter of course and see if we can re-balance it, might be able to get some weight off it!

I agree about rear wheels though, you wouldn't feel a thing

Magnesium is a myth IIRC
