You haven't helped at all LOL That's way off what I would ever touch in real life, and therefore the same goes for GT6. That is the best way to ruin a good car, especially your toe and camber settings (4 degrees front camber is fine, but the rest is so wrong it's not funny)
Simple place to start with ANY FR car which you want to drift:
Most of my drift cars in GT6 are set pretty much the same and all are pretty much there bar minor tweeks.
Height - 20-25mm drop (adjust the rear +/-5mm depending on whether the car is oversteering or understeering too much.
Spring rate - stock
Dampers - FR-4 and RR-4 (up the rear to 5 if it's too understeery). Any stiffer than this and it won't work on stock (soft) spring rates.
Camber - Between 3 and 4 degrees front (more camber makes car more stable on big angle but less stable/more twitchy on low angle). 0.0 on the rear, you want the back tyres sitting flat on the tarmac to give you maximum traction. No variation on this. It's a standard drift setup in real life.
Toe - Stock. 0.0 on front and 0.20 toe-in on the rear.
Diff - 5/60/60 No ifs, ands or buts
I haven't found a single car yet that this doesn't work on as a good base. All you do then is fine tune. I raise or lower the rear of the car 5mm, stiffen the rear ARB, add/remove camber on front (but still always between 3 and 4 degrees)
The geometry, for what it's worth, is exactly what we put on all cars when they go for alignment.
Hope that helps everyone
