I have a R33 4door which I love. 5 speed manual, crossflow trust intercooler so the engine bay looks standard and mines ecu , dump pipe off turbo ,uprated sway bars and raised boost. I picked up some secondhand Bilsteins and used them for about a year . They are great. Just had the front ones rebuilt at Heasmens for $276.00 a pair. Going to have the rear ones done soon. Bilstein's being rising rate are nice and compliant when cruising but stiffen right up when you start pushing them
