So I guess either one of the inserts are good for 650 lb spring pressure.

I hope he brought a new pair of draws. My brother in law was in Lights of 6-9 and the times got lower and lower almost every round. If I remember correctly his fastest time was a 4.01 and that wasn’t competitive.

JMO but if it’s pulsating now you making it thinner is just a temporary band aid. The rotors are made with a hard material and the pads compressing them and the heat makes it almost impossible. Even with a band and a new bit at the perfect speed chatter is most likely going to happen. Are new rotors not obtainable any more or are they ridiculously expensive? I’m only speaking for myself I don’t have a lot of money so when I get something which is normally more than I can spend I usually weight out all options. Most of the time doing it the right way the first time is the cheapest in the long run.

Sounds great can’t wait to see some track videos

Thanks Howie.
