As a recap from my last two track events, I wanted to lower the rear and update the springs. I replaced the 6 leafs with Hotchkiss pieces and measured the anti squat because I run offset hangers and couldn't use the supplied pieces from Hotchkiss. This achieved exactly what I wanted, 1" drop in the rear and very close to ideal 4 degree antisquat angle.
Since the rear was lower, the front needed to be lower. Once I lowered the front to have very slight rake (1/4" difference along rocker pinchweld front to rear) the lower arms were too close to the bumpstops which are alread urethane 11/16" pieces.
In go the spindles and up go the t bars. Now the clearance is excellent, I'm 4 3/4" ground clearance at the K frame. Its 24.5" from the fender lip to the ground passing through the center of the wheel.
I have been running a 275 40 in the rear (26.7") and a 245 40 front (25.7). The 275s can rub the outer wheelhouse from the inside on extreme manuevers, plus the height differential from front to rear is not good. The answer is to drop the rear size to 255 40 (26.0) which fits nicely on the 9" rear rim.
Once the tires are on I will do a proper alignment. I'm interested in hybrid road race DOT tires anyway.
