Thanx guys, both great points. I love the way my X5 steers, period. its razor sharp, goes exactly where I point it! I do suspect that I will need to replace my steering rack in the near future(slight leaks). So, this made me consider the servotronic option, both racks are the same price (from my local wrecker) and I have NCS Expert to do the necessary coding. so why not! as far as running large wheels and tire, I do have the 255/55r18's at the moment, and may go for the larger 20" wheels somewhere down the road. this would be a cool option in the quest to have "every single option ever available to any X5" lol. no , maybe not all, just the really cool and useful ones!
thanx again for the opinions.
