look at the east coast shootout results from last mth. it was clear, 21.5 or go home. whether ur sponsored or not.
I think I went the wrong way with gearing for the 17.5. I should be going up in pinions instead of down and lowering the FDR and relying on the torque of the motor instead of trying to increase RPMs to pull me through the corners. My son's car is exactly the same chassis, but very different driving styles (he doesn't know what an apex is no matter how many times I teach him) and the cars still turn the same lap times roughly. They look real stable, accelerate well, corner without push or oversteer and don't spin out when the throttle comes back up. They have just enough roll tuned into it so they don't flip or go 2 wheeling.
Regardless, you're right, 21.5 is the right way to go and is the weakest link (other than my driving). I don't expect it solve all my problems.
2 large hole shock pistons front and rear, 50 wt oil.
Associated green springs rear
Associated purple springs front
rear shocks leaned in at about 45 deg. (last hole)
front shocks leaned in at about 40 deg. (middle hole)
ride height 6 mm fully loaded.
droop, 6 mm below ride height front, 5 below back
font toe 0 deg
rear toe 2.5
-1 camber front and rear
caster might be 1 deg front and rear, but is probably neutral
This is extremely stable for me, but I could go softer on the front springs if I start to traction roll.
