I've just had the KW V3 Coilover Kit + HLS2 (Hydraulic Lift System) fitted to my 2018 370Z Nismo and I have to say, I love it!!
- Height Adjustable
- Bump & Rebound Adjustable
- Front axel lift system at the touch of a button
- Auto-drop on turning off the engine
- Integrated button, illuminating while in operation
- Compact hydraulic pump, fully concealable in the boot/trunk.
Huge thanks to Abbey Motorsport on this build! We're not aware of anyone else in the UK with this full kit – but if you know someone who has it, let us know. We also couldn't find any examples online of such a 'factory' install as the one they achieved.
I wanted to drop the Z as low as was practical to still have the ability to lean on the tyres in corners without rubbing and to minimise bottoming out under compression. I like to drive my Z. I didn't want it just for show.
It was important to me to have a top-quality coilover kit with the ability to tune the damping to my preferences. I like a taught feel with a balance between responsive handling and mechanical grip. To this end, by also ensuring we could get the right camber settings, an Eibach/SPC camber kit was fitted. Mark at Abbey helped tune the bump and rebound settings for me and I've very happy with the result. I'm going to drive it as is for now and see how I feel. Initial feeling is I could go a little harder on bump and rebound settings but it feels so much more planted now!
I also wanted to make it over speed bumps... Enter the KW HLS2 system. HLS = Hydraulic Lift System. 2 = two wheels (front only). This is the only option on the Z as the system needs coilover suspension and the rear has a separate vertical spring / diagonal damper setup.
(Note - The HLS kits can be retrofitted to both KW and select alternative coilover brands. Contact Abbey Motorsport for more information, letting them know you saw this via "Sprint7 of SportZnTouring's write up on the nissanportz forum".)
So, why not air?
While air has come a long way, it was all about driving dynamics, plus, if any part of this lift system fails, it falls back to just being a static suspension system. For me personally though, the HLS pump is so compact it can be hidden away from sight completely, as if it was factory fitted... Plus, the sound the HLS pump makes it relatively unobtrusive. It's brief for the duration of lifting the car and has a kinda cool whine to it. Much better when compared to the grrrrrrrrrrrrrr of air compressors. The compactness of the HLS pump and the sound is also why I didn't go for air-cups + coilovers.
For the button, we considered various placements and decided to mount this where the left-hand drive starter button would go. In terms of it actually fitting in the space, it was the best option. It's within reach and the best placement aesthetically. Plus, the lock icon looks a bit rubbish and I rarely ever look at it...
Thanks again to Abbey Motorsport!
