That is my rear disc. It's worn.

280mm disc
AP Racing CP5111 caliper + adaptor bracket (believe these are Elise OEM kit).

What is it?

What is the PCD of the rotor to the bell?

180mm-ish (measuring with a tape, so could be 178mm, 182mm, etc)

It does have a number but..... aluminium corrosion.

Not sure why I have 1 piece disc on front and 2 piece on back.

Although..... Wilwood


Took these off tonight.

Been a while since I had the time.

Any input welcome.


I'm convinced it's a wilwood ultralight rotor. I remember a receipt for a few hundred quid in the folder when I bought the car for Wilwood something and I'm not aware of anything on the car that is obviously wilwood. Unfortunately I lost the folder when I got my van broken into a few years ago.

It's a quality rotor whatever it is - but just don't know for sure what it is, and at the prices I'm not prepared to try and buy!


Its a custom disc not "off" anything oem as such.

Could be these ? https://www.rallydesign.co.uk/product_info.php?cPath=562_1214_1216&products_id=10024

No way of knowing just by looking at it will need measuring up properly to confirm

If it is this one cheap enough for a 2 piece disc.
Ex-2005 roadster  owner, i will be back :D



Yeah I think that is what it is. measurements stack up

Discs were in region of £250ish 4.5yrs ago, so pretty feasible price.
