The BAD AST Project - Faze II

[astroracer]

Haven't updated the thread in while because I had some "issues" I had to work through.
When I did the initial suspension design I used a stock Astro spindle as the jump-off point to develope the upper and lower ball stud and outer tie rod pivot points. This was a BIG mistake on my part. I figured the 2" dropped spindles I purchased would be basically the same other then the 2" higher spindle location. Wrong!!! EVERYTHING was different! The upper & lower BS points are farther inboard and the Tie Rod point is not even close! I really dropped the ball on this one. My mistake, I SHOULD have measured the aftermarket spindle from the beginning but I was lazy....
I spent last weekend setting up the 2" dropped knuckle and brake corner in one of my spindle jigs and re-measuring everything. Sunday afternoon and evening were spent remodeling all of the points in my UG geometry file and I worked until 11:30 last night updating my geometry points and plugging the new numbers into my suspension program.
The upper and lower control arms will be shortened a bit and the shock and steering rack require relocation but it's not much of a tear-up on the main frame design. The inner rack points didn't change (cross-car) which dictates the upper and lower control arm inner pivot locations so no change there. The new outer tierod point actually brings it back towards the stock Corvette outer location. I can't see any issues with bump steer with the new rack location as Suspension Analyzer optimizes that internally which gave me the new location.
Tonight and this weekend will hopefully see some work done on the relocation of the components and some redesign of the control arms and rack crossmember and brackets. I will also be updating the motion file to check clearances so I have a bit of work to do before I get comfortable again...
