Hi guys

I'm looking at getting a lift kit installed for my 2005 GU IV patrol . This would depend on price variance between 2inch and 3 inch .

I don't go off road that much . I'm after a basic, cheaper kit- Possibly IRONMAN - 3inch if possible

What other mods would be needed for a 3inch lift ? I'm looking at getting this installed at a shop. What are advantage and disadvantages between 2 inch and 3 inch . How much should I be paying ?
Any recommendations of workshops ?

I will be running 33inch Cooper all terrains.
