Like me... if the Coupe is 4x100 (i may be wrong)

Can I just type that into eBay & any 17-18" 4x100 rims that pop up, assume will fit?

Standard pcd for a coupe is 98 not 100

Coupe wheels are 4x98 but you can fit 4x100 with wobble bolts . The biggest hurdle is the brembo callipers as they are big so you need a alloy that has an et of 35 to miss the brembo's but also you need to look at the spoke profile for clearance too . You can run spacers if the et is low and the spacers will increase the et .

Hope this helps .

Spacers reduce the offset. The offset is the distance between the centre line of the wheel and the mounting face. The higher the offset the less likely the wheels are to clear the brakes.

your right Dan , I got it round the wrong way .
