This article compares the specs of the KW V3 coilovers vs the Bilstein PSS10 B16 coilovers to see which is best.

At the bottom is a table comparing the specs of the two types of coilovers.

Initial Thoughts

Some initial thoughts on the two coilover kits


Bilstein PSS10 coilovers are adjustable but is it enough?

Price.

Both kits are targeting the same audience ie customers who want a premium brand and want to spend around 1500 Euro.

Key Points

The KW V3 coilovers have more adjustment that the Bilstein PSS10 and when we are talking coilovers, range of adjustment is key.

Other Points

Other than that the kits are roughly the same and are typical of German made coilovers. This means they are not supplied with top mounts, you use the original top mounts. Height adjustment is done with the spring seat and the springs may or may not be interchangeable.


KW V3 coilovers seem to have a good price but is that enough to beat Bilstein?

Summary

On the whole, the KW V3 are the winners over the Bilstein PSS10, the KW V3 coilovers cost slightly less and have much more adjustment making the decision a no brainer (assuming KW V3 are available for your car).



NOTE: This article is looking solely at the spec sheets, it is possible, that even though the Bilstein PSS10 has less adjustment than the KW, that the PSS10 actually performs better. The only way to find this out would be to compare the two kits on the same car.

Price

As mentioned above the Bilstein tend to be more expensive than the KW.

KW Wins.

Design

Specifically damper design. KW use twin tube dampers. Bilstein PSS10 are montube

Bilstein Wins

Independent Bump/Rebound

Be able to adjust bump and rebound independently of one another is a huge plus, especially for cars used on the track regularly.

Bilstein PSS10 adjust bump and rebound together, KW adust independently

KW Wins

High Speed Bump

Bilstein make no mention of their dampers having separate valving for high speed bump.

KW say they use a seperate valve for high speed bump but this is not adjustable.

Either way, KW wins

Low Speed Bump

Both kits have adjustable bump

High Speed Rebound

Again, Bilstein make no mention of an independent valve for high speed rebound.

KW do

KW Wins

Low Speed Rebound

Both kits have adjustable low speed rebound

Height Adjustment

Both kits use the spring seat for height adjustment.

Draw

Application List

How many cars are covered by each coilover kit. More cars covered means more likely a kit is available for your car which means a win.

KW V3 coilovers are available for slightly more cars than the Bilstein PSS10.

KW Wins

Spring Options

Both the KW and the Bilstein use progressive springs. This may mean it will be difficult or not recommended to switch the springs to something with a different rate. In other words KW and Bilstein are not using standard 60mm ID linear rate springs which can be easily swapped out for springs of different rates.

Draw

Weight

Both kits uses the same design ie spring seat height adjustment, this should mean the weights of the kits are very similar

Draw

Top Mount

Both kits uses the stock top mounts

Draw

External Resevoir

Some KW V3 coilover use external reservoirs but not all. Bilstein make no mention of any PSS10 kit using external reservoirs.

Slight Win KW

Reputation

Highly subjective measure but I would say the KW V3 coilovers have a slightly higher reputation than the PSS10 coilovers.
