7+ Best Lexus LS400 Coilovers: The Ultimate Guide
Are you looking to buy coilovers for your Lexus LS400?
The Lexus LS400 is a popular luxury Japanese car, particularly among “VIP” car enthusiasts. In this blog post, I’m going to give you the 7 best coilover suspension kits for the LS400, so that you can lower yours in comfort and style.
The Best Coilovers for the Lexus LS400
BC Racing BR Series
LS400 models made for: 1990-2000 (UCF10, UCF20)
Lowering: 1-3 inches, 2-4 inches on the Extreme Low option
Dampening adjustment: Yes, 30-level
Price: $1195
The BC Racing BR Series is one of the most popular coilover kits in the whole world, and for several good reasons.
It is BC Racing’s entry level kit and does a superb job of being the perfect all-rounder that can handle both comfortable daily driving as well as track duty, all for a super low price.
Another reason why this kit is so popular is the amount of customization options that BC Racing give customers. From custom spring rates and valving, to Swift Springs, Extreme Low, rear camber plates (on applicable models) and more, you can basically put together the perfect kit to suit your needs.
They come with monotube dampers that give you 30 levels of dampening adjustment (simultaneous compression/rebound) which allow you to really fine tune the ride and handling to suit your requirements and quickly change them if you need to.
The regular kit will lower your car from 1 to 3 inches, and if you opt for the Extreme Low option, it will go up to 4 inches lower than factory. The height adjustment is done by the shock body, which ensures you have full suspension travel at all height settings. This not only makes for a more comfortable ride, but it means your dampers will last longer at low ride heights since they won’t be bottoming out all the time.
These coilovers have proven over and over again to take almost anything thrown at them, with many people using them for all kinds of things from frame scraping daily drivers to regular track use.
When you take into account the customizability, the build quality, the ride comfort, handling performance and value for money, there are few other kits on the market that can compete.
They come with a 1 year warranty and are also fully rebuildable, with BC Racing selling all the individual parts to do the rebuild.
You really can’t go wrong with these coilovers. They are the perfect all-rounder for both street cars and cars that will see the track.
Features include:
- Ride height adjustment from the shock body
- Lowers ride height from 1-3inches, Extreme low option goes 2-4 inches
- 30-level adjustable dampening (compression/ rebound simultaneous)
- Monotube dampers with linear valving
- Rebuildable with all parts purchasable from BC Racing

Lowering Range: 1-3 inches, Super Low goes 2.5-5 inches
Dampening Adjustment: 24-level rebound adjustment
Price: $1799
The Fortune Auto 500 Series is a very impressive coilover kit offering several things few other kits do.
For starters, what makes these coilovers special is that they are modular, meaning they can be upgraded. So if you decide that you need 2-way adjustable dampening with external reservoir, you don’t need to buy a whole new kit. Instead, you send yours in to Fortune Auto and they will upgrade them for you.
These coilovers are hand assembled at Fortune Auto’s Virginia facility, and every single damper is put on a shock dyno, tested and matched in pairs to be within a 3% tolerance. This ensures that every single kit that leaves their facility is absolutely top quality, with minimal chance of issues.
And to back that up, they offer a 5 year warranty, which is one of the longest in the industry and speaks volumes about how much they believe in their product.
The dampers themselves have a monotube design, using high pressure nitrogen and a high flow digressive piston which gives the driver more feel and control over the car. They have also incorporated a “blow-off” technology to keep the ride comfortable even over rough surfaces.
The springs are made from premium chrome silicon alloy which ensures superior performance, ride quality and a long life with minimal sagging. Swift Springs are available as an optional, which are a good idea if you intend to go super low and want that extra bit of ride comfort.
Fortune Auto will also customize these coilovers to suit your needs including custom spring rates and valving, and they even have a super low option that goes up to 5 inches lower than factory if you really want to slam your car.
These coilovers really are an amazing kit, and aren’t even that expensive compared to other high-end coilovers, making these a fantastic choice whether your LS400 is a daily driver or a weekend cruiser and you want a more performance orientated setup.

LS400 models made for: 1995-2000 (UCF20)
Lowering Range: Not specified
Dampening Adjustment: 36-level, some models have 24-level
Price: $1999
If you are looking to improve the handling of your LS400 and want only a moderate drop, the RS-R Sports*I coilovers are one of, if not the best option available for the LS400.
RS-R are very meticulous about the way they design and build parts, making every product to the highest standard possible. Their range is limited, making parts for only a select number of cars, which allows them to make the best possible product for every application they produce.
The Sports*i are the ultimate performance coilovers made by RS-R which are still intended for street use, offering maximum feel and handling and specifically designed for sports driving.
Ride height on the Sports*I’s is adjusted by the shock body, meaning you retain full suspension travel at all ride heights, even at the lowest setting. This made for a more comfortable ride and a longer life for the dampers.
These feature monotube dampers which have either 24 or 36-level dampening adjustment depending on the model, and have steel bodies and special damper oil developed by RS-R for maximum performance even at high temperatures.
RS-R develops the dampers to not only have optimal damping force but also stroke rate, to ensure the best possible feedback and comfort for the driver.
The springs on these are the Ti2000 titanium composite springs developed by RS-R to be light weight and more durable than steel.
These coilovers also feature a helper spring on some models to help increase the stroke length, giving you more grip and input transfer to the driver.
The strut mounts on these are a steel plate with rubber bush, and on some models can be upgraded to aluminium camber adjustable plates with pillowball mounts for more responsive handling.
If you are looking for premium coilovers that offer the maximum handling performance both on and off the track, these coilovers are for you.
Features include:
- Ride height adjustment by the shock body
- 36-level dampening adjustment (24-level on some models)

The Black*I kit has been specifically designed to go to super low ride height ranges while retaining as much comfort as possible.
These coilovers give you a wide range of height adjustment, and the dampening force and spring rates are harder than the other kits to accommodate the low height and prevent bottoming out.
They offer 36-level dampening adjustment from monotube dampers that use steel shock bodies. The oil used in these dampers has been specifically designed for the Black*i series and is different from the oil used in other kits.
The ride height adjustment is done on the lower mount on these, giving you full suspension travel even at maximum low settings. These kits are shipped from factory set to 90-100mm ground clearance on most car models, assuming all else on the car is factory.
The strut mounts are the same aluminium and rubber setup used in the other models.

The Neomax coilovers are modular, giving you the option to upgrade to 2-way individual dampening adjustment with external reservoirs.

These coilovers have a lot of positive reviews online and many happy customers, and come with an 18 month warranty, making these a great option that is more budget friendly.
