If I go any lower than 35-40mm, then the ARB with foul on the drive shaft and it's expense that can be avoided if I'm being sensible about it. In terms of budget, I could probably stretch to Eibach shocks as well if it's going to gain me anything, but if they're not absolutely necessary, I'm happy to stick with the factory fitted option -just so long as they're not going to wear out in super quick time!
