Hello guys,
I know there is quite a lot of experienced track enthusiasts on this forum, and please help me with a situation. I was a t Ridge Motorsports park yesterday (near Seattle). During high-speed braking (typically from 4th or 5th gear), the rear wheels just dance left and right. I talked to a couple instructors, and they suggested lowering the rear tire pressure. It only helped very little, and I don't want the pressure to be too low.
I come to this track quite often, and frankly also experienced the same thing in the past on the R. At first I thought it's the grooves on the pavement, but this becomes more obvious & happens at more braking zones as I pick up speed. Is this because R has very little weight at the back and has a front-biased braking power?
Thanks so much for your advice. I hate to see the car in front pull away from me because of this!
