Hi everyone, this might sound stupid but are RL7's the same offset and width front to back? I ask because when I bought my car I also bought 5 RL7 alloys and was told there was a full set plus a spare. They all measure 9" wide and 18" diameter, I assume all alloys measure slightly larger than actual size as I measured the misses 16" wheels and they measure 17". Any help would really help, cheers all.

They measure 18" from the outer edge of the rim but I just assumed that the tyre sits in the rim half inch. I've got 5 all the same size and width and just wanted to make sure the fronts are the same as the rears, cheers.

They also did an 18inch version which got a reputation for cracking. The 17inch version seems strong from my experience.

Hi,

I have a set of 17 ins RL7's which I want to refurb and fir to my Cerbera,...I would like to know how to check offset before I launch into refurb img them....

Again anyone know dimensions?

As an aside ideally I would prefer 18ins ones ...or if someone has 2 x18ins ones I would be interested...

The offset is written on the inside of the 17" RL7s ET41 (can't remember exactly where) - presume that the 18s will be the same. Spiders are ET42 (fronts) so it ought to be one of these two numbers.

The fronts should be chamfered on the inside edge of the rim so they don't rub on full lock. I'm pretty sure the offset is the same front and rear.

I've just been out and measured the diameter of my 18" RL7s and they are closer to 19.5" if you measure from the outer edge of the rim so your measurements sound correct for a 17" wheel. My old 17" rl7s had 17x8.5j printed on the inside of one of the spokes but it never had the offset printed on. My 18s have nothing printed on them.
