Hi
@jpatrick1821 - So... at the moment I actually don't have the mild lowering springs on the car anymore. What ended up happening was that there was a clunking sound in the suspension when I would go over bumps at low speed. Unplugged Performance did some troubleshooting, but they couldn't find the culprit. I took it to Tesla in March, and they replaced the front stabilizer bar, but it still didn't solve the clunking.
I then had UP remove their springs and put my original springs back on, so I could take it back to Tesla service, in April. The clunking was still there - though it was less pronounced with the factory springs. Tesla confirmed they heard the clunking as well, and they replaced some components with the latest versions.
That solved the clunking, and -- get this -- improved the ride quality dramatically! I'm guessing my suspension now feels like most other Model 3's (where most people aren't complaining about the harshness of the ride...)
At this point I've got the lowering springs sitting in a box in my garage, and am considering whether or not I want to switch back to them. I I think the ride quality was still better with the UP springs than I currently have, but had my car driven like it does now from the beginning, I probably wouldn't have sought out the softer springs in the first place.
I don't love that the mild springs lowered the car quite a bit -- it may look good, but it means we do scrape things every once in awhile (I scraped going into our driveway once, which isn't particularly steep... and parking lots can be tricky under the front bumper). And, I don't love having aftermarket parts in place, since it voids the warranty for the suspension. But on the other hand, I did like the ride quality more...
So... you may want to talk to your service center, and ask them to change out your suspension components for the latest versions. (If I didn't have the clunking sound, I doubt they would have done it). If not, I'd say you should go with the mild springs!
Here are the parts they added for the stabilizer update in March:
