-more freeforming for what to burn my money on underway. I'm debating the configurable Haldex controller. I do like the ability to reconfigure the torque split front-to-rear, but given the design of the .:R drivetrain from the factory, are the mechanicals really designed to endure a 60/40 or 55/45 torque-split permanently? How do they compare to an A3 or A4 which has this setup by default? I'd love to drive my car in Sport or Race mode all the time, but I have this creeping suspicion that 6 months or a year down the road I'll be suffering some sort of horrendous repair bill that the dealer will blame on aftermarket modifications..
