How can I control this, and could it be the reason for my terrible 60 ft. times?

stock backspacing is like 6.5" most aftermarket wheels are 4.5" the lower the number the farther out the stick.

Opps, yes your right, but the stockers are also 6.5" wide and a +28 offset, which sucks them in.
Most aftermarket 20" rims have 0 or negative offsets. Mine are -12's..

Yeah I drop my t-bars, and I'll look into those LBZ

Do you have green keys or leveling keys?

I had a buddy with green keys and it was still to "cranked" to do a good boosted launch with the bolts pulled all the way out. I changed out some guys Readylift keys to a stock set after he found out he couldn't lower the bars enough.

try launching softer.
