As Alyn says its down to personal preference and what you use it for...
I have:
Eibach ARB's front and Back (23mm & 24mm)
Whiteline Lateral Lock Rings for Rear ARB
Whiteline Roll Centre / Bump Steer Kit
Whiteline ARB Heavy Duty Mount Kit
(Will have when fitted) HardRace Trailing Arms, Adjustable Control Arms, rear drop links
Whiteline Anti-lift kit
Whiteline Top Mounts on the Front
Group N Top Mounts on the rear
Eibach Coilovers
Super-Pro gearbox mount bushes
Whiteline Steering Rack Mount Bushes
Scoobyworld Front and Rear Strut Braces
I would def recommend getting new ARB's - whiteline are OK but people say they rust. My Eibach ARB's are very good
Anti Lift kit makes a difference when hard accelerating, and changing things like steering mount bushes, and gearbox mount bushes make a difference at keeping everything stiff...
