      Next on the to-do list is replacing the support bearing on the propshaft, after the dyno it didnt look pretty, it had seized and rotated in the rubber and the suspension geometry, right now i have way to much negative camber around, front -2,5 degrees and rear around -2, problem is that i cant get that much more positive camber because inĂ¥t the front my wheels Will touch the arches probably, i have 15mm spacer for the rims to clear the calipers(4-pot
      Porsche)
      I think the ultimata geometry for drifting the car would be something like
      0 to -0,5 camber both front and rear
      0 toe or maybe slight toe in front
      And a bit toe-out for the rear

        Nice!!! How stiff suspension springs are you running?

          I dont know the numbers on the springs right now, but same stiffness both rear and front, havent really tried setting up the suspension yet, kW v3 coils. Maybe i should have the damper softer in the front vs the rear for weightshifting when i enter the corners?

            Looks nice! So are you running rwd now? And are you sure you made 726 wheel horse power with the GTX35 or is it crank horse power?

              4wd of course! If i made it rwd it would be handicapped
              Im sure 726 on all four wheels, on E85, 2,7bar boost max
              The turbo seems to be really good, but now its bottomed out, more boost than i have only gives more heat, not so much HP,but its tuned rich for safety, we would see more HP With less fuel and different cam setting, cam setup right now is not for highest hp, but widest powerband

                Today i aligned my wheels, car is primarly for drifting on gatebil events, so up front i set it to 0 degrees camber and 0 toe, rear i could only set -1 degree camber for some reason, i wanted as close to 0 as possible, toe out 0,6 degrees rear.
                The reason is i noticed my Tires were more worn on the inside, ran -2 degrees of camber all around and i wanted to have more Tire in the ground, and more toe out in the rear for easier turn in(turn out?) of the rear.
                Also tried adjusting the kW coilovers, set them hard on both rebound and compression on the rear and almost the softest setting front, the reason is weightshifting on turn in, i want it to dive when i brake to let the rear out.

                Also tested the new map abit today, the engine feels less aggressive now, strange cause i have much more torque when the turbo kicks in, but wider powerband, feels much more Easy to drive anyway and that was the goal so, on Saturday there is a local dragracing event and maybe i do a Run or two, without launch control they also have a try drifting on that event, very tight course but i think i Will try it atleast, guessing it will be really hard when its so tight..
