Well, considering I can do the Powder Coating & Fab work myself, the only thing I’ve had to buy so far would be the ES Bushing it and the Subframe Bushings which together have me in around $250 ($150 for the ES Kit and $100 for the Subframe Bushings)
Honestly, only thing I’d have no problem doing would be the Powder Coating or the boxing/bracing of either the Subframe or Arms etc etc but I wouldnt want to get into the removing of the bushings, metal sleeves or installing new bushings.
