About the Lexus LS400
The Lexus LS is the flagship luxury model made by Lexus, made to compete with cars like the BMW 7 Series and Mercedes S class.
The first LS400 was released in 1989, with the second generation released in 1994. Their powerful V8 engine and rear wheel drive setup, as well as their very comfortable ride and luxury orientated design make them popular with car enthusiasts, especially within the VIP circles who focus on luxury sedans.
One of the most popular modifications when it comes to LS400s is lowering. However, it’s important that this is done right in order to retain the comfortable ride characteristics that the car had from factory.
Coilovers are one of the best ways to do this, and in this blog post I’m going to give you the best coilover options available for the LS400 today.
The Best Coilovers for the Lexus LS400
RS-R Sports*i
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)
- Ti2000 titanium composite springs
- Special RS-R damper oil
- Dampers designed for extra stroke
- Steel top mounts with rubber bush, pillowball camber adjustable optional on applicable vehicles
- Made in Japan
- 1 year or 12,000 miles warranty

If your priority is getting your LS400 as low as possible, such as if you are building a VIP style car, the Black*I coilovers are for you.
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.
If your priority is getting your car as low as possible, and you want a high quality suspension kit that will still retain ride comfort, this kit is for you.
Features include:
- Ride height adjustment by the shock body, designed to go extremely low

The Fortune Auto 500 Series is a very impressive coilover kit offering several things few other kits do.

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.

The Top Coilover Picks for the Lexus LS400
I’ve thrown quite a few good options at you here, which can make it difficult to decide on the right coilover kit. So now I’m going to give you my top two choices from this list, one for best value for money, and one for best coilover to go low.
Best Value for Money: BC Racing BR Series
My pick for best value for money goes to the BC Racing BR Series because I believe these coilovers have the best combination of quality, customization and reputation for being a good product.
These coilovers as so widely used and proven that they are a safe bet – you know you are getting a good product for your money.
They also make these coilovers for all LS400 models and will let you go super low if you opt for the Extreme Low option.
The only thing these coilovers don’t have is the ability to upgrade them, however for 99% of people this isn’t going to be a concern. If it is for you, then go with the Silvers Neomax.

Best For Low: RS-R Black*i
Who better to go to for super low suspension than the masters of VIP car culture. The Japanese have been lowering luxury sedans as close to the ground as possible for decades now and have mastered the art.
RS-R are known for their extremely high quality coilover kits, combining a fantastic ride with good handling. They only make kits for a select few vehicles, so count yourself lucky that they make one for the LS400.
I have no doubt that the RS-R Black*I is as comfortable as it gets while you struggle to get over a speed bump or scrape your frame rails your driveway.
So for maximum low and a comfortable ride, go with the RS-R Black*I.
