What are coilovers?
The term "coilover" is short for "coil spring over shock". A coilover is part of the car's suspension made up of a shock absorber inside of a coil spring. This provides damping without torsional loads. Most coilovers allow adjustment of ride height and preload, using a simple threaded spring perch similar to a nut. More advanced adjustable coilover systems use a threaded shock body, along with an adjustable lower mount for ride height adjustment, while an adjustment knob is used to adjust damping. Switching the spring for one with a different spring rate will change the stiffness of the car's suspension. A higher spring rate is stiffer than a lower rate.

How much does shipping cost?
Shipping is completely free within the United States as long as the order is over $49. All coilovers ship for free.

What payment methods are accepted?
We accept all major credit cards, Apple Pay, Amazon Pay, and PayPal. We also offer very simple payment plans through Affirm Financing.

How long does delivery take?
If in stock, standard coilover kits ship within 1-2 business days. We ship primarily with DHL. Tracking will be provided the same day it ships so you can see what the expected delivery date is. The average time is 2-3 days, but some locations may take up to 5 days.

How long does delivery take for custom builds?
Custom-built coilovers take 5-7 business days on average to ship depending on order volume at that time. We always ship with UPS ground. Tracking will be provided the same day it ships so you can see what the expected delivery date is. The average transit time is 2-3 days, but some locations may take up to 5 days. All kits other than the BR Series are built to order.

Will a signature be required for delivery?
Yes. We always require a signature for proof of delivery to help protect everyone from theft and fraud and to ensure you receive your order. No exceptions.

How do I know if a product is in stock?
We don't show inventory levels on our website to ensure our custom-built products are still displayed in search engines. For this reason, please contact us if you would like to check inventory on any product. We usually respond within a few minutes. SF Racing stocks most Sport Series kits and some DS Series. Almost all others are made to order.

What is a custom build?
A coilover kit is considered a custom build when you choose custom spring rates, pillowball mounts, or any alteration other than how they come standard from SF Racing.

Will higher spring rates affect the lowering amount?
Yes. When you increase the spring rates, they can decrease the amount you can lower the vehicle. Very stiff spring rates will not compress as much from the vehicle's weight, thus resulting in less of a drop. Please consider this when selecting custom spring rates!

Do all kits include adjustable camber plates?
Due to the factory design of some vehicles' suspension, camber plates are not always available. Camber plates will generally only work on a McPherson strut design. Some car manufacturers like Lexus and Honda use A-Arm style suspension on their cars, both front and rear.  This style of suspension will not support the use of a camber plate, so you would need to use either an adjustable arm/link, or other camber adjustment setup. 

Are end links included?
SF Racing only includes end links if the coilover kit requires them. Most cars do not require new end links.

Do I need an alignment after the coilovers are installed?
Yes. You will always need alignment anytime a set of coilovers are installed or when your ride height is adjusted. Changes to your suspension can make the vehicle dangerous to drive. We also recommend a professional alignment to avoid excessive tire wear.

Are the coilovers preloaded out of the box?
Yes. All coilovers come preloaded. Be sure to adjust your ride height properly so that you don't accidentally adjust the preload. Some vehicles use a separate spring and shock. These are not preloaded.

Are the coilovers preset out of the box?
No. You will need to choose your desired ride height and damping settings. A good rule of thumb is to start in the middle and work your way either stiffer or softer depending on your needs. 

How much will they lower my vehicle?
The average range of adjustable drop range is about 1 to 3 inches from factory. The amount varies per vehicle and based on many factors.  

What is the warranty?
SF Racing offers a one year limited warranty against manufacturer's defect. 

Can I return the kit?
You can return the kit if it meets the following requirements:

  • Return is requested within 30 days of your order.
  • The kit is uninstalled, new condition, and in the original packaging.
  • You accept that all shipping charges will be deducted from the refund. Please note that shipping charges are very high as they're currently shipped from overseas.

How can I be sure it fits my vehicle?
Always verify the year, make, and model of the vehicle. It's also best to verify the chassis of your vehicle. All products are for 2WD vehicles unless otherwise specified. We do have kits available for FWD, RWD, and AWD models. If you're unsure, please ask!
