For off road racing use.

  

This list has just a few fresh ideas, however, it shows how little things can add up.

Cruise servo motor                                                                     - 1.

The rock guards for the front springs                                             - 1.

Aluminum water pump pulley                                                       - 1.

                                                                                    Total   - 96

For '92 and up cars:

ASR servo motor                                                                        - 2.

                                                                                    Total   - 98

For '93 and up cars:

    A special engine calibration is required.                                    - 5.

                                                                                   Total - 103 pounds

 

 

A weight reduction of 100 pounds will change the power to weight ratio enough to

make the car about .1 second quicker in the quarter mile. Of course, handling is

also improved.
