I drove Tony's car on Sat and it was excellent, the amount of traction was awesome and it felt totally planted even with it pi**ing down
I then went out with James and it was very different, if James had the diff that car would be so much quicker as it will be able to put the power down (not that it wasnt bloody quick
)
I think if you have a 335i put aside £2k and get the map and diff and you will love it
