Whats the offset on those? looks a bit low

Gotta admit Im not much of a fan of aftermarket alloys, I usually prefer the manufacturers does a nice selection of alloys which suit the vehicle much better.

ET38 stock is ET49 and narrower wheels.

Vauxhall dont make suitable wheels for the brakes im planning so these were cheap and i like the look of em.

I had another look and the tyres dont stick out from the body with the wheels straight front or rear
