I currently have a 2003 sti with 18'' Prodrive/Speedline wheels. I am about to buy a 54 plate sti with 17'' standard wheels.
Would it be possible to swap the wheels betweeen the 2 cars?

Anything I need to be aware of?
Thanks.

 

Should be a straight swap as both 100mm PCD. A 54 car may be just at the beginning of the 05 cars that changed to 114mm PCD from 100mm PCD on the 03 and 04 cars. Just have a look at the stud spacing as difference is obvious.
