Thanks John

I thought the wheels were stamped ET42?

Hmmm. I notice my tyres are 205/45. Does it matter?

Your speedo will be out

Compared to 50 profile yes, but why would it be any more out than with 225/45?

Because the profile figure is not a static figure, but a percentage of the tyre width.

So if you have a 205/50 r16 tyre, and a 225/45 r16 tyre next to each other you'll find the profile height will be the same.

Running 205/45 r16 tyres, will mean your speedo will over read by 3.4%. When you're travelling at 60mph, your speedo will read 58 mph.

You mean when I'm travelling at 58 my speedo will read 60 surely?

Will the 15" wheels from the other coupés fit a 20vt with 10mm spacers?

I'm pretty sure you'll need 16's to clear the brakes.

even if they clear the calipers I think you would need a 20mm spacer at least

can i ask why you want 15s on??? are you planning a rocket quater mile or something
