Well you said Cal-Mini 3" Body lift, otherwise
I'd say it was their springs settling, best guess
is just settled springs, you could get a set of
springs from Hawks, or go to 4 door springs
for more rate up front.
The 5.12:1 axle gears in the man trans give
a slightly higher final drive ratio than an auto
with 4.62:1 cogs. (comparison done with a 16V Geo)
I found with 235 tires, the speedo on my auto kick
read 100% correct, the stock 205 tires caused a 2-3
MPH over speed missread, and the power difference
is not really noticable, at least to me. (pre turbo)
