To Much Rear Rebound
Poor harsh uncomfortable ride
Car loses rear grip in general
The rear suspension packs down progressively on bumps, getting harsher and harsher. Rear of the car bobs and jiggles around.
Delayed corner exit oversteer, the car can understeer on the corner entrance and oversteer the corner exit, this is very undesirable!
Too Little Rear Rebound
The rear of the car feels floaty and scary when going fast, especially under undulations or pavement height variations. Feels like a boat.
The back of the car feels unstable and scary, especially in cornering and transitions, car wants to suddenly snap into oversteer, not good.
The car might drag launch ok but loses traction past 40 feet or so.
The car has a generally unstable feel, even if the front feels good.
When making shock changes I suggest initially making big steps like 3-4 or even more clicks depending on how your shocks respond so you can definitely feel the changes. If the changes feel good and you go faster, keep adding more until your lap times drop or the car feels bad and back off a click or two. Remember in most cases less damping is more! When making adjustments make sure you take a notepad and write down exactly what you are doing. With the 4 corners of a car, it’s easy to get confused about what you last did and that’s important in case you overdid it and have to go back.
This guide can help you solve many handling issues with just some shock adjustments. I encourage you to go out on the track with your car and experiment. Adjusting your shocks wrong is not going to make it hurtle out of control so don’t be afraid to take some swings at it. Once you gain a good feel for what the adjustments do, you can apply this knowledge to different situations and different cars. Now go enjoy and go fast!
