[jybute]

The F/R weight on the 318is seems wrong. Or atleast wrong when compared to say... the 325i. Wouldn't the smaller M42 bring the ratio closer to 50/50?

[DEATH2000]

It should, yes. I didnt create the list though so their is a possibility it is an error.


On a side note, when did you get an X5? If you havent already Jybute, you should check out Project Technik. Its an Alberta based group. www.projecttecnik.com. My board name over their is Vader.
