Car in Track mode> Gear selector in Drive > Double tap traction control (ESC) button> PTM menu appears, any selection works (on cars without PTM, 2 orange lights for ABS and traction control illuminate) > really press the brake all the way to the floor> Press gas to floor> when RPMs settle to around 3500rpm, release brake. Boom, He Gone!
From google:
So which is better, for the car to 'squat' or not? Quote: When running a C8 Z51 in the quarter mile, it is generally better if the car squats slightly as this indicates good weight transfer during launch, maximizing traction and providing a quicker acceleration off the line.
When running a street car in the quarter mile, it is generally better if the car doesn't squat significantly, as excessive squatting can negatively impact traction and handling by causing excessive weight transfer to the rear wheels, potentially reducing grip and leading to wheel spin. This is why race car setups often incorporate "anti-squat" suspension geometry to minimize the amount of squat during acceleration.
Key points about squatting in a race car:
However, a small amount of squat can be beneficial in some situations:
Key points about squatting in a race car:
- Reduced traction:
When a car squats too much, the rear tires can become overloaded, leading to reduced grip and potential wheel spin, especially on high-powered cars.
- Camber changes:
As the rear of the car squats, the rear camber can increase, further reducing the contact patch of the tires and impacting grip. - Anti-squat design:
To counteract excessive squat, race cars often utilize suspension geometry with a high "anti-squat" percentage, which helps to maintain a more level stance under acceleration.
However, a small amount of squat can be beneficial in some situations:
- Weight transfer:
A slight squat can help transfer weight to the rear wheels, which can improve traction on certain surfaces, especially when launching off the line. - Tire grip optimization:
Depending on the tire compound and track conditions, a small amount of squat can sometimes help maximize tire grip.

On the drag strip, the C8 cannot do a "line lock" burn out without a modification, the Rapid Exit Double Paddle Declutch can be used on a drag strip just after the car passes through the water box and prior to the start line to dry the tires. I see many C8's on the drag strip go through the water box and do not conduct this very important step to avoid excessive tire spin from wet tires at the start. Some tracks do not allow you to avoid the water box since it spans the width of the lane.

Additionally, members on this forum have found success launching on a drag strip in either Race or Sport mode. I personally found that Sport Mode worked best for me resulting in little to no spin of the All Season tires. My attempts in Race mode provided tire spin.
