Last week, I reset the ride heights on our DW9 to within the range of what DW suggests as a starting point. Here is where they were set to:
LF: 5-7/8" RF: 6-1/8"
LR: 6-3/8" RR: 6-5/8"
(Since it matters, we are running on Hoosiers.)
Once I got the car on the scales, it had 113 lbs. of LR bite, so I changed the jacking bolts/slider evenly to adjust the bite to where I wanted it. (I changed it to 56 lbs... Since DW suggests 20 lbs., I didn't want to go overboard.)
I've been told that if you add/remove weight in a corner evenly (1 round in the left front, 1 round out of the right front, etc.), it will not affect your ride heights that much... So, after scaling it, I never thought to recheck it. (I know, that was my 1st mistake...)
Once we got closer to race time, everyone in the shop noticed that it appeared that the right-front was sitting lower than the rest of the car. I've been boggled ever since as to why, but I have a theory:
Is it possible that adding 1-turn in the coil-over slider changes the spring rate/ride height on that corner at a different rate than the jacking bolt does? If so, then the problem I have is that the LR is too high--which makes it look like the right-front it lower. Does this make sense?
From now on, I'll measure during scaling, too...but I want other opinions on this.
