I watched it this morning - don't forget that fb viewing in real time isn't an option for me.He specifies in the videos different springs for different setups such as street, street track, full track? Did you not see that? He actually talked about that quite a bit? That is why he offers those different options for purchase as well. He has become a big believer in the JRZ stuff and he explains that in the videos as well.
I found this episode to be better and more informative than others I've watched pieces of.
Around 16 minutes in, he gets into it being a real PITA for him to try to fix something when a customer went off on his own for some of it, and I understand that completely. It shouldn't be his problem to solve when it's the customer who changed something without realizing the implications of doing so. Especially if KB isn't keeping all of the engineering data right at his fingertips. I don't blame him a bit.
In some ways, KB's thinking isn't all that much different from my own, but in others (and certainly at the detail level for a few things) it does differ.
KB's philosophy definitely feels more toward "stiff spring/soft bar" than most, that his approach is more about dialing back from race rather than building up from OE street.
400-ish for performance street - I'm really thinking that's where a dual-purpose occasional street/fairly serious HPDE car might end up - is definitely up there, somewhere around 2.0 Hz. Not un-do-able, but you and your passengers had better be able to appreciate a firm ride all the time.
Fun fact - his Koni yellow/H&R Race recommendation really isn't much different from my Koni yellow/BMR GT500 Handling combination. H&R's are about 25% stiffer (I just don't care for the H&R amounts of lowering or the fact that the H&R front and rear springs are both variable-rate).
