The 2013-2020 alpha chassis Cadillac ATS has one of the greatest vehicle chassis GM has ever produced underneath, however the non-MRC suspension is full of performance compromises, as with all OEM suspensions. Even though the ATS is considered a sports coupe/sedan, they still have to market it to the general public meaning the stock suspension leaves a lot on the table. Our ZZP ATS coilovers are a perfect compliment to that amazing chassis and pair very well with our ZZP front sway bar, ZZP trailing arms, and ZZP rear sway bar.
Our coilovers can be adjusted from approximately stock height to approx. 2.5" lowered (however, we do not recommend these for those looking for stock ride height or stock ride characteristics). Damping adjustment can be fine tuned for your particular height and tire fitment, or preferred ride. The lower the damping is set the smoother the ride, however if you're looking for perfect tire to fender fitment you might have to crank the damping up to not damage those precious rear quarters. Even if you do not change ride heights, playing with damping can get you different handling characteristics; if you're looking for more oversteer on track or auto-x then crank that rear damping up.
The alpha chassis ATS in stock form has a near 50/50 weight distribution, and a very centered handling bias so with our testing we landed on 8kg front and 10kg rear for spring rates. These spring rates, combined with our chosen spring heights, and shocks/struts that are valved specifically to these spring rates and chassis mean you will get excellent ride quality while retaining fantastic performance. Ride height adjustability is done via the shock body in the front, meaning spring pre-load is preset for the optimal combination of ride quality and handling. Rear height adjustment is done via the included high/low adjuster, and preload is set via your rear shock body. Front camber can be adjusted at the top of the strut via the camber plate, or down at the knuckle mounting point with our slotted lower mount.

We offer double the warranty of BC's and other competitors, 2 years against any defect. This shows how much we stand behind our product. Our coilovers also come with more dampening adjustment range so you can fine tune for your specific build and desired ride quality. Our coils were built with every climate in mind; being based in Michigan we know how much the elements affect suspension parts, so we made sure the welds are up to our standards as well as the powder coated lower collars are reinforced to withstand rust. All other components are anodized, or powder coated to resist rust. We know that you're going to love everything about these coilovers.
Fitment note: GM has updated the front steering knuckles for the ATS. These new part numbers are 23118085 and 23118086. If your vehicle needs servicing of these knuckles and you replace with the updated part numbers there will be a slight clearance needed on the lower coilover mount. Just grind a slight amount off and it will fit in the casting on the new knuckle. Any questions please email customerservice@zzperformance.com.
