Some context for my 2016 Golf Sportwagen car.
1. I run in a "modified club rules" class, not SCCA. I can pretty much do whatever I want suspension wise and remain in class. Big constraint is tires are limited to 205 width, min 140 tw.
2. I have both audi tt arms (recent mod) up front and vorshlag plates. Front camber should not a problem. Might be able to reach -6 if I wanted to. I've been running at -3 before adding the arms but need tire pressure to prevent the outsides from rolling over at -3. Arms and plates add about 1 degree caster (total +2).
3. Rear camber is somewhere between -1.25 to -1.5.
4. Car rotates reasonably well with some spring tricks out back - bump springs, slightly larger rear bar, spring rubbers all make it configurable and setting things to lift oversteer is easy.
5. Tires and tire pressures - have been running RE-71R at 50psi in the back, 46 front to limit rollover. I added more camber capacity up front in the hopes of lowering the pressure and slowing outside wear.
6. No LSD.
Given everything, I'm thinking of increasing neg camber out back to around -2 to -3 vs -4.5 up front.
Back camber doesn't get too much discussion. What do you folks think about the back in a car that has lots of potential grip up front?
Thanks,
Bill
