Brother, there is a 180 degree difference between off roading suspention and rally suspention, kindly make up your mind what you want.
If you are requiring your Vigo for off roading only, than go for ARB/OLD Man EMU suspention, they are the best in the world and have a dealer in Lahore. Complete suspention will cost you around 250 thousand. This will include standard lift of 2 to 3 inches. I recently ordered one for my Defender 110 and although most of the articles have arrived yet the dampers are still on the way from Australia.
The above ARB is for off roading, not rallies, if you are intrested in 4x4 rallies than the set up of your Vigo's suspention has to be completely different i.e. absolutely no lift because lower center of gravity is requied for high speed manuvaring. You will need two shocks for each wheel, with combined psi pressure of 400-450, there are so many other things for the rally like you take out all extra weight like extra seats, rear doors. To rally prepare your vehicle you need atlest 500 thousand. Also, be prepared to invest 100 thousand after every rally to cover the normal wear and tear. If you roll over, which almost every driver does, that wil cost another 400 thousand
Once you make up your mind, let me know, being a member of an off roading as well as 4x4 rally club, can help with all the required information.
