I'm just waiting until you find out the best option there is, then I plan to steal the idea (ditto on all the other builds on here). Kudos to the pioneers that put in the time and money figuring this stuff out. If it weren't for "freaks" like you, poor guys like me could never get close to...
I know Redline doesn't recommend drop brackets or plates for caster correction (they recommend the washer mod and bushings). Is there a particular reason for this, or is it just loss of ground clearance?
