How to adjust shocks? So beginning of the year I bought a set of double adjustable Vikings for the rear of my car and they’ve been great! The question I can’t quite find on google is what to adjust if I’m having different issues.
I.E. wheel hop do I need more rebound or compression less?
Wheel spin do I need more compression or rebound less?
Just looking for some of the science behind what to do rather than turn ***** and hope it’s right.
Looking to dial this in just a bit more here soon.

We have some tips on our Help & How To Section. https://midwestchassis.com/p/help--how-tos
HELPFUL CALCULATIONS & SUSPENSION TUNING:
Q: What should I do if the car hooks then spins?
A: Typically, this is a result of the rear shocks set too soft on extension and too soft on compression. The suspension generates more leverage/hit to the tires than the shocks are set to control. The result is the tire gets flattened, wound up, hooks but bounces and unwinds therefore losing traction (Hook, spin, hook).
Q: What should I do if I spin as soon as the car launches?
A: Soften the extension on the front shocks to promote additional weight transfer and soften the extension on the rear shocks to hit the tires harder. This will generate more traction.
Q: What should I do if my car spins the tires down track?
A: Soften the compression of the rear shocks. Double check the spring rate and make sure the spring rate on the car is correct. If the springs are too stiff, the car may be riding on the bumps of the track.
Q: How many clicks should I turn the shock when I want to make a shock change?
A: Usually, 3-4 clicks will be enough to make a change the car will recognize.
Q: Since installing my power adder, I seem to get more tire shake. How can I fix this problem?
A: Tire shake is a function of the suspension moving with more force than the shocks are adjusted to “dampen”. To make an adjustment, stiffen the rebound first, then stiffen the compression to help hold down the tire once it gets applied. The goal is to match the damping values with the level of force/energy passing thru the shocks.
TIP: When setting ride height, start with the shaft 1/2 way in/out. Fine tune from there. Be sure to guard against shocks bottoming out. If the installed height of the shock is too short, and the piston (on the end of the shock shaft) hits the base valve (at the bottom of the shock), damage will result.
TIP: When choosing rear springs, it is suggested to choose the softer option. A softer spring rate will typically be more consistent over a range of starting line conditions.

bought them on ebay, really i just wanted to know what to do just for my own need to know how they work.
i would call a place like Midwest chassis or UMI and I'm sure they will help you understand and set them up for your needs even if you didn't purchase the shocks from them. talking to someone on the phone (or in person if you can) who knows these cars and how to set them up properly will be way more beneficial to you than what someone can type up on here for a guessed response. my .02
