Hi mate
Love what you're doing to your Sportswagon.
I also have a redline Sportswagon and just love it
I have done a few mods heads, cam, exhaust, intake 313rwkw/795Nm
I track mine too and its awesome blowing away sportscars.I am interested in what you've done with your brakes. I have the 4 pot standard Brembos. The car pulls up well but from 200+km/h BUT I don't get a lot of confidence so I end up braking quite early at the end of the straights. I have been looking at the CTS-V rotors can you tell me how you found the brake upgrade? Have you tracked it since?. Did the CTS-V calipers clear the redline rims? Was hooking up the rear hand brake a problem?
Also how do you find the switch to coil overs?. Is it much harsher than the FE2? I am a bit stumped at the moment because I love the ride and handling of FE2 on the road but on the track its limited. I am basically looking to do exactly what you've just done and would appreciate your insight.
cheers mate, go the wagons!
