Anyone running KW adjustable HLS suspension?

you can always add the hydraulic kit. KW sells the hydraulic kit by itself, albeit pricey. The 2.5" diameter is plug and play for F430/360 as far as fitment.

Or if you want cheap way to do it, you can get a manual weight jacker the circle track guys use. Basically it is a hydraulic kit but not using electric pump but manual. It is pretty simple and uses hydraulic principles and can raise about 1"

 

Yes you can run their kit for 2.5" spring diameter. You can even use the stock spring. The top perch on the factory shock is 2.5" the bottom is tapered to slightly bigger than 2.5". I recommend installing the hydraulic cups on the top if possible. All you need is to lower the lower adjuster/perch for the thickness of the hydraulic cup when it fully collapse.

The factory shock is a really good shock made by Sachs. I've run it with much stiffer springs and it can control it no problem.

 

Keep in mind the motion ratio on the front of F430 is about .7 if I remember correctly. That means 1" travel on the shock equal to 1.4" at the wheel.

 

This is one example of manual jacker. There are few manufacturers.

Stock springs are not 2.5", it is much bigger, I forgot the dimension exactly. However, the stock hardware is made to fit 2.5" springs. Ferrari uses rubber isolator as well as adpater to go from 2.5" to the whatever dimension the stock spring is. So if you use the stock spring, you will have to put the hydraulic in between the rubber isolator and the shock upper perch.

 

If you change springs you going to have options for the rate. Factory F430 is 323 lb/in front and 596 lb/in rear. If you want to maintain the same, you can get the rear really close at 600lb/in and front at 350 lb/in. eibach brand is easiest to get as you can buy it from wide variety of store and it is excellent quality.

 

It has been a few years. I'm curious if anyone else have ran their kit...

 

I recently bought the KW HLS kit for OEM coilovers. Not installed yet, will be done during the winter.

 

Same! mine are supposed to ship from Germany here any day and are set to get installed in September. Looking forward to it.

 

Hey guys. Bringing this thread back from the dead to see if anyone has added the HLS to the OEM system?

 

Funny thing as with the last time this was posted I am waiting on another set of the KW’s - this time for the F430. This time ordered with the front lift. And like before will hopefully be installed sometime in September - or maybe October / November as both supply chain and install dates are worse than last year

 

Get the KW’s and don’t look back. The front lift has worked flawlessly since new and adds a ton of convenience for day to day driving. The suspension is unreal, dampening and overall performance and comfort is better than my 2020 Portofino.

Thank you all for the reply. My plan is to installed the HLS on my factory coilovers using H&R coils. Do you see any issues with this combo? I'd like to drive with about a finger gap above the tire, but need the HLS to get up my driveway and other inclines. I've seen other pneumatic options, but prefer the idea of hydraulic.

 

For preservation purposes I can see why you want to stick with OEM suspension but for me superior performance of the KW coilovers was worth it as I occasionally do track days.

 

I’m thinking that my OEM shocks need a rebuild, the suspension doesn’t seem very compliant and harsh, especially going over small cracks or bumps on the freeway. Has anyone rebuilt the OEM shocks? Or should i go with KW? I don’t need a lift. I’m happy with KW on my NSX and Porsche964. Any thoughts? I’m also thinking about replacing all the flambloc.

 

Bump thread for any updates on the KW HLS installs? For those that have done it, how is the durability? Where did you mount the hydraulic pump unit?

 

I have had the lift working during the 2022 season.
During the install, I did some minor modifications to it though.
Ditched the KW hydraulic pump and the KW ECU-CAN box.
Ordered a hydraulic pump built to my specs, built a alu box that I covered in OEM style fabric, OEM Ferrari screws to match interior.
No damage done to the interior during mounting, using OEM existing mounts (KW install needs cutting the mat)
Built my own ECU to control it, connected to CAN to get vehicle speed, rpm etc

Interested to know more about your ECU controls and your updates to the pump. Does it automatically lower at a certain speed or disable above a setting? Also, what was your reasoning behind getting a custom pump made? Space/efficiency/etc?

Your setup looks really nice! Any pictures of the components before you installed them?
