I'm looking to purchase a set of 18" Prodrive alloys, the design commonly found on the P1.

They are advertised as 'PD10' can someone advise if these will fit straight onto a '53 Plate STi Type UK?

Thanks in advance.

The 18" come in two forms, ET53 and ET46 (whatever that means!). prodrive's site suggests the latter should fit on an STi:

This is the offset of the wheel, the distance between the centre of the wheel, in mm, if mounted and viewed from above, to the actual mounting face.
Smaller offset means the wheel sit closer to the outer arch giving clearence to the inner(not including -ve offsets), or in this case the Brembo calipers.
Some aftermarket wheels have the correct offset but the spoke design can foul the calipers. Prodrive wheels should be no problems.
