Coilover Installation and Tuning at ACG
The key component to making your car handle its best.

 

We can install any type of aftermarket coilovers on your street or a track vehicle.

On your average street car we would install the coilovers and dial in the height and firmness (if dampening adjustment is available) to your liking. Any coilover setup needs to be driven on for the suspension to break-in. During the break-in period the suspension settles and compresses so the car lowers even more. We offer one complimentary coilover adjustment in order to bring your car to the desired height after the suspension settles.

We are experienced in installing and fine-tuning the high-end coilover setups from Moton, JRZ etc. on Porches, Nissan GTRs and many other makes and models.

Since every vehicle is different you need to call us in order to get the installation quote. Keep in mind that coilover installation normally takes 4-5 hours so arrange your schedule accordingly.

 

Front end Lift Systems:

We possess the unique know-how on installing the front end lift system on practically any vehicle. We use KW HLS (Hydraulic Lift System) which is designed to provide a limited number of sports cars to avoid road clearance difficulties such as street bumps and steep driveways. With a press of a button the front end of your car would lift in order to clear an obstacle. This setup increases the handling characteristics of the vehicle (works with KW Coilovers) and solves all the clearance issues you may have. While KW only offers the HLS for several vehicles we are able to integrate it on yours.

Why Coilovers:

Coilovers are the “best” suspension modification in that the struts are designed to work with the springs. You get the coilovers if you want to be able set up your car's height and ride firmness all in one package. Coilovers also allow you to fine-tune your car/suspension parameters for racing as well as daily driving.

Another feature that coilovers allow you to do is corner weighting, also known as corner balancing. In short, corner weighting evens out your car’s suspension during turns so that your vehicle reacts identically in both left and right turns.


Coilover Adjustment:

When it comes to the coilover adjustment for a track vehicle, it is not only a skill but an art. I will be brief in my explanation in order to cover the basics and to give you an idea on where to start. Let's look at the shocks.

Compression (bump) adjustment is responsible for how fast the shock compresses when you hit a bump on a road or a corner at a track. Compression is normally adjusted on a bottom of a coilover assembly. On a softer setting the shock will react and compress faster giving you a softer ride. If compression is set too soft, the car may lean too much into a corner and float. On a harder setting the shock will compress slower when you drive over bumps and imperfections. If set to the hardest setting this will translate into possible loss of traction as the shock will not be able to transfer the energy fast enough and react to the road surface bumps.

Rebound adjustment controls how fast a shock will return back to its original position after you drive over a bump. Rebound is adjusted on the top of the coilover assembly. A soft rebound will provide a comfortable ride at slower speeds but the car would be unstable at higher speeds. A higher rebound would offer more stability but may result at a loss of traction. If the shock would not rebound fast enough the vehicle will "skip" over road imperfection and slide.

You really need to know what you are doing in order to keep the fine balance between the compression and the rebound adjustments. It may seem straightforward when reading about adjusting the parameters; however, to get neutral handling out of your car you need to do the adjustments at a track and test your car after each adjustment. A correctly set up vehicle will slightly understeer at the apex turn-in and slightly oversteer when exiting a turn.

For a street / occasional track use we like KW Coilovers. They come ready and set up with recommended settings specifically for your vehicle from the factory. If you are following their instructions on setting up the car, keep in mind that 1 click is 1/4 of a turn regardless of what version of KW street coilovers you are using. The compression is adjusted from the bottom of the coilover assembly. When looking from underneath the car, clockwise rotation will account for higher bump (suspension reacts slower / harsher ride quality) and vice versa. The rebound is adjusted from the top. When looking at the shock from the top, the clockwise rotation will account for harder rebound (suspension reacts slower / harsher ride quality) and vice versa.
