Stiffer than Hotchkis? I don't think so.
Def. not stiffer than 350EVO
Hotchkis specs:
Front 1 3/8" (35MM) Hollow (Bar Weight 13.5lbs)
3 Position Adjustable
Rate Increase over stock
+9%,+32%,+63%
Rear 15/16"(24mm) Hollow (bar weight 5.5lbs)
3 Position Adjustable
Rate Increase over stock
+54%,+92%,+146%
Cusco specs:
Front sway bar is 2 way adjustable (20% stiffer than stock and 37% stiffer than stock), rear sway bar is fixed (73% stiffer than stock).
Hotchkis is a better value imo because of the adjustability. Cusco rear is fixed. Hotchkis is 3 way front and rear.
