The wheels are the Oz Super Tourismo's, subtly different to the RS wheels and don't have the extra cost of needing spacers too.
I did consider getting an RS before I bought this ST but at the time purchase price was £10K more for the RS and that was just for a cancelled order and not the spec I'd have wanted. Course they are holding their money a lot more now but I'd have had to stretch much further financially just to get a standard RS, and I already had an ST so lot of the performance parts transferred straight over. Only driven an RS gently but really prefer the way the ST makes power/torque low down rather than having to get the bigger RS turbo spinning.
Didn't intend it looking like an RS just went my own way with what I wanted to change and that's how it came out.
Upgrades-wise, Collins stage 2 map, RS clutch & flywheel, Quaiffe diff, Eibach springs, Bilstein B8 dampers, Pro-alloy IC, modified K&N induction kit, RS oil cooler, full mongoose exhaust with 100 cell cat, Profile Automotive rear roll-bar, Ferodo DS2500 pads and probably more I can't remember.....
