Yang,
Purple fronts are pretty aggressive, you can try plaid or 2x pink. A softer t-bar would help, or you may have been way to soft and the weight transfered too fast and the car would break free. Trinity red dot traction would give more bite then paragon. Maybe a softer center spring, which did you have? There are many possibilities..lol.. Post exactly what you had and what would happen to the car. Make it easier for me to take a guess at
