"there is not a complete aftermarket subframe including shocks and brakes out there for less than 6 or 7k"
That statement is incorrect....my Martz aftermarket front subframe was $3050 not including freight and includes Rack and Pinion, Wilwoods, QA1's, steering linkage and is 200 lbs lighter than a factory unit...
