Tried a few 0-60 runs yesterday with my SPS A8. Can't break through the 4.5s wall with my 16 SPS A8, no matter what. It's frustrating.
Here are my parameters
- Vehicle: 2016 Scat Pack Shaker A8 at 17k miles
- Tires: Atturo AZ850 275/40/20 all around (which were supposed to hook better than stock)
- Altitude: Sea Level
- Temperature: low 50s
- Road: Well paved street somewhere here in Socal
- Full tank of gas (I know it's extra weight, but I'm a light person at 140lbs)
- Traction Control: On/off (tried with both. off resulted in an unwanted burnout, lol)
- Launch Control: Tried with it at 1500RPM and without
- Launch Technique: With and without launch control, it's left foot on brake, right foot slightly applied on gas, then releasing left foot.
- transmission set to SPORT. Via paddle shifters set to first gear and letting transmission auto upshift
Observations:
- car hunting for traction and losing time there
- when not sliding and fishtailing around too much at start I'm getting between 4.5s-4.8s. But just can't get past the 4.5s no matter what.
Are there any accepted best practices for launching this car on street tires to achieve the manufacturer claimed 0-60 of 4.2s? I know much wider tires would do the trick, but then that wouldn't be close to stock and according to manufacturer's claims.
