Lightweight Battery
One of the ways to improve the performance of your car is to reduce weight-- we've talked about this many times. The stock battery is usually a whopper, often weighing in at over 60 lbs. We now carry a line of lightweight batteries that offer similar cranking power to the stock units, at less than half the weight.
We recently installed one of these lightweight batteries on the M3 race car project.

Here you see the empty box where the old battery was, and the first thing we had to do was grind away the rust and repaint area:
Next we constructed a new battery tray with aluminum angle stock. We used the mounting bracket that came with the battery kit and tied it to the car with threaded rod and eye bolts. The finished install is good and solid:
