Totally agree,
Just fitted mine this morning, although a tip for ya. Make sure you spray penetrating fluid on all the bolts, then have a cuppa while it does it's stuff.
Even being very gentle, one of the ARB bracket bolts sheared, & was a real pig to remove. Required copious amounts of heat to break it free.
Definately makes the car feel "Tighter" & more precise.
For the hell of it, I fitted a tuning box to ours as well. I know, I know, all the die hards will say they dont work very well, but I needed it to be removeable, & undetectable, which an ECU tune isn't. I must say it has given it a big dollop of torque, removed the >1500rpm flat spot, mid range gears have much more oomph about them & hopefully will get better economy from it as well, but I will let you know in a couple of real world driving weeks.
As for the ARB, just do it already, but down to pricing, check your vag dealer as surprisingly they beat Vagparts by quite a way!!
