TSW Spa's aren't available in the correct PCD . Roughly speaking this is something to do with the distance the studs are apart, they only make PCD 100 in 18 inch and you'll need PCD 114.3 x 5, which seems to be something of a standard for larger Japanese cars, like the Supra, RX8, etc. Difficult to get much info on TSW Spa's but I found a site selling 114.3 x 5 Spa's but these are 19 inch wheels.
