This was in the manual that came with my Penske shock, i thought it was pretty helpful.
Street Tuning: Symptoms and Suggestions
⦁ The simplest way to adjust in your suspension is to find a loop approximately 5 miles long where you can create multiple situations, sweeping corners, tight or braking corners, harsh bumps. It is also ideal for you to find a quick or easy stopping place (fuel station, bank, food store) Ride on the factory pre-settings, make changes, evaluate changes and continue and repeat in order to dial in “your” ideal setting.
⦁ Write down your original or current best setting. Then change only one adjustment at a time. Be patient, go back to your original settings if you get lost.
⦁ Bring your tools to adjust, also bring a flashlight to see shaft travel of the shock.
Harsh over bumps: If shaft travel is not within 1/8” from bottom (Black) bump rubber:
⦁ Go softer with compression, 2 to 4 clicks at a time (counter clockwise), if better continue going softer.
⦁ Reduce rear spring preload (increase sag) -1 turn at a time on spring perch.
⦁ Change to a softer spring rate.
Harsh over bumps: If shaft travel is clearly into the bottom (Black) bump rubber:
⦁ Too soft on compression can bring about a harsh feeling by allowing too much shock travel and compressing the bump rubber. Go Stiffer with compression, 2 to 4 clicks at a time (clockwise), if better continue going stiffer.
⦁ Increase rear spring preload (reduce sag) + 1 turn at a time on spring perch.
⦁ Change to a stiffer spring rate.
Wallowing exiting corner:
⦁ Stiffen compression, 2 clicks at a time. (clockwise)
⦁ Increase rear spring Preload (reduce sag). 1 turn
⦁ Slow down rebound, 2 clicks at a time (clockwise).
⦁ Change to a stiffer spring rate.
Slow turn-in:
⦁ Raise fork legs in triple clamps – More fork tube sticking out of top of triple clamps.
3mm-5mm per change
⦁ Increase rear eyelet length, 1/2 to 1 turn at a time. – If applicable
*Cannot exceed 12mm of thread exposed.
⦁ Soften fork compression
⦁ Reduce fork Preload (Increase sag)
⦁ Speed-up rear rebound. Counter Clockwise or (-)
Mid corner push - front:
1. Stiffen rear compression
2. Slow down fork rebound
