The BJ4 Setups are pretty standard though. From the Highest bite blue groove or clay, to running on super loamy tracks, there are only a handful of changes I really make.
Bite: LOW ---> HIGH
Fr Springs: Green ----> Silver
Fr Oil: 30 --> 35 ---> 40
Fr Shock Upper Mount: 2 ---> 1
Rear Sway Bar: Off ---> On
Rear Oil: 25 ---> 30 ----> 35 (extreme bite/heat only)
Rear Spring: Green ----> Silver
Rear Wing: 7" HD Full Lip ----> 7" no Lip ---> 6" HD partial lip ----> 6" HD no lip
That about 98% of the setup changes I will make....super low bite, startes with all the stuff on the left, and super high bite is the stuff on the right. We have the JBRL series here in CA, and I can usually watch a couple of guys run in practice, and guestimate the approximate setup using the model above, and it is usually really close.
Hope this helps!
