Just checking - are the Spyder wheel centres 95.25 PCD with a bore of 56.6mm?
Thanks.

Same as MGF or Rover metro/100.

Seem to remember that the wheels fitted to the Spyder were OZ Superlegerra, and these had a different PCD to MGF and Metro/100 (possibly 110 if I remember) as I did try to put them on the Libra to see what they looked like and they didn't fit!

My Spyder is definitely 95.25 (Three and three quarter inch) PCD and uses standard MGF wheels as well as the KN Racing ones that GTM originally supplied. Maybe yours had a hub conversion Phil? (and therefore Nik!)

For info, Elise S1 rears also fit (front or rear) as Elise S1 had 16" rears and 15" fronts but used the same 3 3/4" PCD, slightly different offset so they stick out about 10mm more (ideal if you are trying to use the AP four pots)

Thanks for all the info. By my approximation, the pcd seems to be about 100mm (I'll have to take the wheel off tomorrow to measure accurately).
According to the link below, this could make the hubs from a Rover 25, 45, 75 or 200, or if it's 101.6mm they could be from a Rover Metro.

I think that link is misleading when it refers to the "Rover" metro having 101.6 pcd (or 4") as it was my understanding that they changed from 4" to 3.75" at the same time they went to the K series Metro & I believe the A series Metro's were never badged as Rover?

The donor for the Libra/Spyder was always the K series Metro/Rover 100 so should all have been 3.75" but some underwent hub conversions during build or in later life as 4x100 is a lot more common so easier to get aftermarket wheels. Or of course 4x108 (4.25") opens up the whole Ford range as all Ford 4 studs were 108.
