For something a little different, I'm not going to present another new variant of a tune that will cure the BTR '86 and Yellowbird handling issues. Rather, I've taken all the tunes already posted and , well averaged them to see if the "regression to the mean" concept works. Now some may say "but, but the tunes were made for specific power and tire combinations, you can't do that..." But I did, and here's what I found:
Front Height = 102
Rear Height = 115
Front Spring = 7.72
Rear Spring = 9.60
Front ext = 5
Rear ext = 5
Front comp = 5
Rear comp = 5
Front roll bar = 5
Rear roll bar = 5
Front camber = 0.9
Rear camber = 0.9
Front toe = -0.06
Rear toe = 0.36
Brake Balance F/R = 6/4
LSD Initial = 15
LSD Accel = 22
LSD Brake = 24
Average Weight Dist = 44/56. Stock 930 Turbo was 37/63 IRL, BTR is 41/59. You can probably get close to 50/50 with ballast but why bother? The idea is to keep some semblance of the character.
Test setup is for a 930 Turbo replica, set for 1340 kg and 450 PP. Test track is Apricot Hill with the Gold Standard lap time of 1:39.0 with Comfort Softs.
First off, a Turbo 930 is a cruddy 450pp car, many other 450 pp cars can meet the time easily, pushing the 930 lower than 1:40 was tough. You can see from the average settings that the general tuning trend is ;
Lower the car, with rear higher than front
Stiffen front springs, soften rear springs
dampers, roll bars average out midpoint, stiffer than stock
Bit of camber f/r
Bit of negative front toe, medium rear toe
Front weighted brakes
LSD roughly low-mid settings.
Tuning does work and do make the car a few seconds better, but...
The upshot is, [drumroll] the average settings don't work too well. I had best times and most consistent control with slightly modified @helseth extreme settings from 16 Jan 14. But, again you can't make a silk purse out of this sow, it has no special capabilities or hidden speed waiting to be unlocked.
