SR+ Rear Sway Bar - Has anyone installed it?

[momo3605]

Hi everyone,

Found out recently thanks to this forum, that the SR+ does not come with the sway bar from the LR models. Has anyone installed the OEM sway bar(not aftermarket) and noticed any improvement to body roll?

I've driven an LR and SR+ side by side, and it's pretty noticeable that the LR has less body roll, but that could also be due to the extra 450lbs down at the bottom

Thanks!

That's interesting, I always thought my SR+ had a ton of understeer compared to my BMWs. No rear sway bar would definitely explain why.

Looks like a future upgrade I'll try out.

you will need extra hardware to mount the OEM rear sway, so don't bother with it, the OEM rear is weak anyway

Yes I have! I bought a rear sway bar from a performance model 3 on eBay complete with end links. It’s definitely an improvement.

Looking to buy one with the end links and do this. Anything else I need to worry about? Bottom covers still fit correctly?

Hit up @UnpluggedP. They can get you a better bar and I believe they sell the oem hardware needed to mount.

I’d need the sway bar end links too. I looked and they are pricey. Bought a sway bar off a performance with the end links and hardware for $175. It would be well over $500 to go the unplugged route.

I sourced my endlinks from eBay from a low mileage car to install my swaybar.

Everything will fit. Sway bar, endlinks, and hardware is everything you need.
You can see the cutout on the rear aero shield for the sway bar here.

Here are the instructions from the service manual,
including torque specs.

I have both OEM front and rear performance sway bars available for purchase but no end links. They were retained to use with the UP sway bars I installed.

Hit me up if you’re willing to buy the OEM bar(s) and get the end links from ebay as the other person did.

I just received the rear bar with links I bought off of eBay yesterday. It has the hangar brackets as well just need the bolts to mount it. I saw the folks using the eibach had to buy longer 10M 1.5x25mm bolts so I may buy some slightly shorter. I’d be interested in the stock ones if anyone has those laying around. My other option is to see how much Tesla wants.

I used ARP 662-1002 M10x1.5x25mm

Another option on bolts:

yellow zinc, grade 10.9.

 

[HitUpOlas]

I have the stock bolts on order with my local service center. 52 cents each. They told me the bolts would be in within a week. 1111154-00-B BOLT,HF,M10-1.5x23

So I went ahead and tried this on my SR+. Bought oem LR bar with end links and installed with zinc bolts. And honestly...couldn’t really tell much of a difference in cornering. Still has a bit of body roll on entry. I suppose Tesla made a reasonable decision to omit on the SR+. I would suggest anyone in the future to do an aftermarket bar or performance bar

This may be true for normal street driving but the guys at Mountain pass mentioned it made a huge difference on the track to the point of almost too much oversteer.
