Forged alloys

[ChromeOrange]

Does any body know if the forged alloys that come on the cup 260 are a wider wheel than the 7x2 spoke forged wheels Lotus do.

Heard the fourteen spoke is 7.5 x 17 and the cup wheel may be 8 j ?

Anybody know the weight difference?

Many thanks.

Cup wheels.

Yes, the 2010 Cup 260 wheels are 7.0J x 16" and 8.0J x 17", front and back, respectively.

No idea on exact mass, sorry, but thought the Cup wheels were lighter.

If anyone would like to give me money so I can buy smoe for my Exige, I'd be very grateful!

All the forged wheels are the same width. Only the 'standard' Elise wheels are narrower.

The forged wheels (both 14 spoke and 5-spoke Cup) are approx 5.5kg and 8kg ish. The regular wheels are 7kg and 10kg approx.

Quite a weight difference!

FWIW, I used this as my reference, regarding size...
