18" x 9" RL7s, Cerb spec?

[phazed]

I have a set of these already that I acquired a while back and use these with a pair of 17"x 8" fronts as track day wheels.

I run a set of 17" RL7s all round as road wheels but would like to change the rears for a pair of 18" so I can run same size for road and track.

So, are these standard Cerb?

If so, are these common, does anyone know of a pair available, have you a spare pair in your garage

They were fitted by the factory but are very rare, almost like hens teeth. Good luck.

Yep, very rare, they were prone to cracking so didn't last very long. I think most were recalled by the factory and swapped for Spiders.

Really !

I thought that RL7s were very strong?

Whatever the reason the 18" ones had problems; ironic that some people swapped them for Spiders.
