I was storing data once every 10 msec (30 sample averages). It made for some interesting data. The SDLogger was used because it was easy to communicate with it over a serial port at 115k baud and I didn't have the time to get the SPI SD code operating. My only recommendation for a street car, would be to use an accelerometer with a smaller range - around 1g or less for better resolution and you could certainly slow the sampling down.

Thanks for the suggestions Mike.

One of my goals for the off season is to get very familiar and comfortable with using SPI. I've already done some testing and communicating between two Arduino's with SPI, and the data logger might be a perfect time to get really used to the code.
