Well if you could bring your own set of wheels (even steelies) then I would hold onto the wheels also to sell. The other stuff you want would be fine to keep on the car.
I could remove the GTspec v-brace panel, trailing links and get the car aligned for you since that will throw it out of spec - this isn't a problem.
Unichip, the stage 1 and stage 2 Essential Speed kit, 4 point ladder bar, coolant reservoir, GReddy SP2, splitters, wheels, shift boot, shift knob, ebrake boot could all be removed if the price is right.
There are other things that I can't take off:
1. you said you wanted the front end protection (that's a given and has to go with the car because once you remove it is useless
2. the polished heatshield (unless you had another to trade me or wanted the car without a heatshield
3. I could take out the foglights, but the switch to turn them on has been mounted in one of the blank clips next to the coin tray. If I remove them you would be left with a hole in that clip or be left with a switch that does nothing
4. Under dash neons - same as above concerning the switch
5. The boost gauge and air/fuel meter in the pod. I painted the pod to match perfectly with SEM paint but I'm not a wiring wiz and took it to professionals to install. I am not willing to mess with removing those gauges (you should have a boost gauge in these cars anyway).
6. You have to have the longer AXR endlinks for the fronts. I couldn't get the stock ones back on once I installed the TEIN suspension (they were just too short). I have the stock rear endlinks and they could be put back on but the front have to stay.
That's about it.
As for the sub rack rattle, I'm not sure. I thought I had it but it seemed to disappear a few days after installing the evolve clunk fix brackets. It was probably tied to the sway bar but it was so hard to figure out where noises were coming from back there. Those greasable bushings worked wonders.
If you know anyone in my area, have them stop by and I'd be more than willing to show the car.
