BimmerBum's E46 Sport Wagon is the workhorse of the group. It serves daily driving duty, regluar autocross duty, and regluar road trip duty. It has nearly 140k miles but it is very well maintained and fairly heavily modified!

The best part about a BMW is balance, this balance is created by keeping all aspects of performance at similar levels. I keep that in mind when performing modifications. Every aspect of this E46 wagon has been enhanced slightly, power, brakes, and suspension/tires. Slight enhancements across the board maintain driveablity while providing for a substantial performance gain.

You can track the wagon's DSP autocross results for the 2009 season here.

Upcoming modifications:

In the very near future race tires will be added for autocross days. I will be running 17 inch wheels with the race tires. The smaller diameter is better for autocross and better on the wallet when it comes to buying tires.

The next major project will be a combination of things. A new exhaust, clutch, lightweight flywheel, short shift kit, Group N engine mounts, and M3 tansmission mounts will be added along with urethane rear sub frame and trailing arm bushings.

Installing the rear sub frame bushings will be a pretty signifigant undertaking so to help make it easier I bought a used sub frame, I will clean it up, fit the new bushings and have it ready to go when the old sub frame comes out.
