NEW RELEASE! KW Height Adjustable Spring Kit (H.A.S. Kit) F90 M5



Golan@AutoTalent.com



AutoTalent | KW Suspension | BMW F90 M5


H.A.S.


We are the oldest KW Suspension dealer in the country! So we can get the best price guaranteed.



The HAS (Height Adjustable Spring) Kit is used for lowering the vehicle in combination with the original dampers, even when electronic damper control is installed. This lowering solution from KW optimizes the dynamic performance and the steering behavior without the electronic damper control deactivated.

Part # 253200CC







The KW Height Adjustable Spring Kit (or "HAS Kit", for short) allows you to achieve the look you’re after on your 2018+ F90 chassis BMW M5 without having to sacrifice your factory electronic suspension. This kit allows you to re-use your stock M shocks, retaining all functionality, while decreasing costs and need for added parts. You get the perfect F90 M5 lowered ride height and retained EDC - so you can keep your variable ride control (Comfort, Sport and Sport+).

You used to have a choice: Aftermarket springs with pre-set static ride height OR fully adjustable ride height with a full coilover system. What do you do when you already have the most sophisticated dampers on your F90 M5 and all you want is increased performance with the ability to set your ride height? The KW Height Adjustable Spring Kit (or HAS kit, for short) is the answer, and gives you the best of both worlds on your street driven F90 M5.

Spring rates are developed specifically for the F90 chassis. The lowered ride height will not only make your M5 car look better (meaner!), but it also adds increased handling responsiveness. KW uses the same high-quality chrome-silicone steel as they do in their top-rated coilover kits, so the springs and adjusters are the quality you’d expect for an F90 M5, delivering both longevity and ease-of-adjustment. HAS kits are wonderful enhancements of your stock suspension, and are a perfect solution for newer BMWs, whether they come with a standard or adaptive suspension system. The KW Height Adjustable Spring Kit is designed to be the best fit and flexibility of any spring kit available for the F90 M5.

Ride height adjustability (5mm-20mm front and rear, or 0.2 inches to 0.8 inches)
Adaptive suspension remains active when equipped
Specific spring rates matched to the F90 M5
Better handling and corner with reduced body roll
Improved look and stance
The F90 M5 HAS Kit comes with the M5-specific springs, height adjusters, and F90-specific bump stops with dust protection system.

is this lower across the board (Comfort, Sport and Sport+) or does it mean that the more aggressive modes can go lower than before while retaining the comfort mode's height?

I have KW HAS on my current F10 M5 and they have been phenomenal w/ zero issues to date. More than likely headed down this path w/ F90 M5 on order.

Are there any negative consequences to lowering with this set up regarding the wear/dynamics/range of the stock shocks?

The drop is set and does not change between the different settings. The shocks are still factory so you can choose between the different dampening settings.

The stock shocks will eventually go out but not anytime soon. I would say scraping the bottom bumper is more of a negative consequence if you don't angle the driveways right

Re-reading this I have some confusion. Is the TOTAL drop .2-.8 inches? Or is that how much adjustability it has ON TOP of the initial drop? The language of the post implies the latter: "Ride height adjustability (5mm-20mm front and rear, or 0.2 inches to 0.8 inches)"

The total drop range is 0.2" - 0.8", for a more aggressive drop coil overs will be the solution.

You still have the ability to go between comfort, sport and sport + on the dampening but overall they will become more firm. I have not had any seat time personally to give my overall opinion.

Would the same drop range of 0.2”-0.8” apply to the M5 Competition model?

Drop will be the exact same as the non ZCP car as the only difference is the spring.

Okay, still confused. The Competition comes from the factory about .25” lower than the standard model. So...

1. Will the Competion be a total of 0.4-0.8” lower from Competition factory drop?

Or..

2. Will the Competition be a total of 0.4-0.8” lower than the standard model?

Competition is lower than the standard F90 M5. Both will be the same drop height after installing the KW HAS.
