i will have another go in a soft direction like you suggest.
Before when i tried those tires and softer suspension the car would be balanced in a drift, but if i let off a little or got a little too sideways then the car would bog a little, then the tires would grab and the car would dive into the inside board. i was also running the tires a little too big maybe? (42.5/45.0)
with black/grey the traction was smoother with varying slip angle, but with 2xpink grip was more like an on-off switch.
thanks again for your help on this.
You never want to see any kind of drift or sliding in a pan car. That will wear tires and kill corner speed.
Also, you may want to try Trinity Zip Grip as a traction compound too.
