Highland suspension on 2019 Model 3
- Thread starter Guod
- Start date
I just finished installing highland springs and dampers to my ’22 M3 LR. It has been over a month since I test drove a highland so my memory might not be accurate, but the improvementfrom stock is huge. Swallows larger bumps much better and does not have any jerkiness over smaller imperfections. It still has suspension ‘sound’ eg when there is a bump you can still hear suspension ‘thumps’ when it rebounds. This might improve over next weeks as the car is noticeably higher than before, new springs need to settle. I would say this upgrade gives 90% of the highland suspension.
I previously tried KONI Active frequency dampers with original springs. I would say it was mostly as harsh as original. There might have been a defect in the front KONI dampers, in 2000-3000km they developed a clunk and I retorqued everything with no improvement. Switched back to original dampers and clunk was gone.
Part numbers for highland suspension:
1344362-00-D Front Left Spring and Damper assembly (185€)
1344362-01-D Front Right Spring and Damper assembly (185€)
1344462-00-D Rear Damper (140€/piece)
1344472-00-B Rear Spring (120€(piece)

Interesting. Can you measure ride height now so we can all see how it compares?
This method, so we all use the same reference.

Thanks for the feedback.
I just looked at the parts catalog, they only seem to have the DUAL MOTOR rear damper, and no damper for RWD.
But I guess that they probably use the same dampers, with different springs, as all cars now have similar weight.
I'm wondering, are the new springs really needed or would new dampers alone be enough?

Highland DM and rear drive have similar weight, DM is only 63kg heavier. So maybe the difference is so small that they can get away with same dampers? Front dampers might also be the same, but as they are sold as a assembly, it’s hard to know. Maybe only the springs differ?
Can anyone check how measurements are in highland?
Just measured 2019 perf hub center to wheel arch/well
Front and rear: 39.5cm

A friend with the Highland RWD did measure and had 39.5cm rear and 40cm front.
On my side (TM3 2019 Performance) i have 39cm rear and front.

There's still no damping related to the Performance Highland on Tesla Catalog. Perhaps the adaptive suspension dynamic adjustment announced is done via a mechanism in the new chassis ? Couldn't find any information still on the web for that despite all Perf reviews out there

The adjuster is built into the side of the shock and controlled with a solenoid valve. It needs inputs from the main ECU to operate it.

It's on Tesla website and most of the reviews with an exploded view. The cast aluminum knuckle is different too. Shorter level at the steering arm mount. Not sure on any other modifications, but I bet they changed it slightly in other ways from the LR.

Excellent, excellent piece of info. That should help a lot to all, myself included, considering the hardware suspension upgrades.
I currently have Konis FSD on my 19 Model 3 performance with OEM springs. Did you have the clicking noise / clunk noise over small bumps? I’m having this same issue and not sure why and where it’s coming from? I’m hoping it’s not the shocks themselves.
Yes, the clunking noise was over small bumps/imperfections in the road.
Similar to the noise that stabilizer end links do when they are worn out.
As I wrote earlier, I disassembled everything, retorqued everything to factroy spec, but the noise remained. Then I reinstalled factory shocks and the noise was gone. I checked Koni shocks on the ground and they had about 2-3 cm of no resistance travel when decompressed.
