This first step may be skipped if
there are more than 320 km
(200 mi) on the brake pads.
2. Repeatedly apply the brakes
from 100 km/h (60 mph) to
25 km/h (15 mph) while
decelerating at 0.8 g. This is a
hard brake application, without
activating the Antilock Brake

1 km (0.6 mi) between stops.

Depending on conditions, this

(60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from
100 km/h (60 mph) to 50 km/h

Rear Axle
The rear axle fluid temperatures
may be higher than when driving in
severe conditions. Drain and refill
with new fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See
Recommended Fluids and
Lubricants on page 11-12.
Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty. Do not drive as
long or as fast the first time the
vehicle is driven on the track or
raced.
Driving and Operating
For extended track use, GM
recommends installing a rear
differential cooler to protect the
rear axle.
Wheel Alignment
For racing and competitive driving,
the vehicle load should be limited to
the driver only and no cargo. The
tires should be inflated cold to at
least 250 kPa (36 psi).
Caution
Using these wheel alignment
settings may cause excessive tire
wear. Only use these wheel
alignment settings for racing or
competitive driving. Excessive tire
wear is not covered under the
vehicle warranty.
