Small update - all listed parts are on,car has yet to be dyno'd but is much smoother and plenty quicker to drive. Intake temps are now consistent but i worry about the intake being a restriction as it's a 2-1 setup. May try to get 2 x BMC filters with aircon ducting to the bumper if it'll fit.
Handling with the coilovers and sways is phenomenal. I know the US guys have had some twitchy-ness with the sways but i like the quick response,plus i can dial out some of the nervousness with the damper settings. A point to note though: HKS Coilover spring rates are relatively high so if you're still on runflats you might have some trouble with potholes.
Will be putting on a set of rims + non-RFT tyres in feb,plus a new set of pads and discs. Stay tuned for proper update photos
Sam - Car was putting out 305rwhp with the DCIs and the GIAC stage 1 so i'd hazard a guess at ~340 or 350 now. Hopefully more when stage 2 comes about.
