Amazon: Ford Escort Cosworth Design 6J x 15 x 40 Alloy Wheels (Set of 4)

yeh in 15" they where fitted to the escort gti They are cosworth "style" but have never been standard on a cosworth.
The cosi rims are much wider.

The subtelty about the cars is very useful, I am comming from the offset that I need. Thanks

as big_wasa says, the real escort cossie wheels are 16" x 8" wide and normally fitted with 225/45's

there are also some narrower mondeo 16" ones in the same style too (I got a pair of 'new' old stock ones for £30 )
