HM is definitely interesting.
The picture you showed is their LT kit which is like 94" wide, (10" over stock 5" per side). They do have a 91" Mid Travel kit but again, it still runs custom shock towers, what looks like 10" stroke shocks but could be 8" stroke with dual rate springs.
I do agree that performance will be better if you cut out the stock bucket. I think the OP was looking for a more economical, not as wide option though. That's Evil and Camburg only (1.5 to 2" over stock) and Evil really if you want a strong setup without using stock spindles. Blitzkrieg, RPG, SVC, RHF, Foutz are all wider I believe (3 to 3.5" wider over stock per side).
