I agree with the above, you end up with a smoother ride, but you do hear the suspension work at lower speeds (10-20 mph) going over speedbumps - it is a whooshing sound, my wife describes it as an old jalopy sound. There are no clicks or other mechanical sounds. The whooshing sound increases as you open the damper valves further. As an overall compromise, I have my valves set at 22 Fronts and 19 Rear.
I installed the Redwood GT suspension upgrade on my 2022 model Y LR with 19" wheels. My goal was a softer ride, at original height.
For the rear, I did not replace the springs and just replaced the shock absorber. I did this to maintain load carrying capacity of the vehicle, while maximizing range of motion of the shock/spring assembly. This approach only works if you are willing to live with the existing height. Redwood's (as well as all other vendors) spring assembly enables height adjustment of the vehicle, but requires some of the space to do that.
For the front, I replaced the entire assembly with Redwood's unit. I was able to set the height at the original settings. Once complete, I don't think we altered the alignment of the car (I have not taken it in yet for alignment - I will do so as a check.)
For comparison, I also own a 2022 Model X. So here are my opinions: (I am using a subjective scale of 0-100, where 0 represents the original Y, and 100 represents the Model X - It would be my goal to achieve a 100.)
- Reducing the cold tire pressure to 36 all around improves the ride of the Y by about 5 to 10 %. In particular, the higher frequency bumps are better absorbed - This improvement is still true even after the suspension upgrade.
- I have 6000 miles on the Y now and I can say the suspension softens with break in. This adds another 10% of improvement to the ride. Overall, with lower pressure and broken-in suspension, the car gets a score of 15, maybe 20, out of 100.
- I only have 700 miles on the new Redwood suspension; it definitely improves the ride; but there are limitations as noted above. Today, I would say the car gets a score of 50 to 60 out of 100. I might be able to improve that slightly, but I think that is generally as close as 100 as I will get.
Would I upgrade the suspension, knowing what I know?
- Redwood's product is top of the line - the fit and finish is superb. (And I can't comment on the competitors)
- It is a very expensive upgrade.
- It definitely improves the ride.
- I am on the fence on recommending it... I think it depends on how important a smoother ride is to you, versus how deep your pockets are, versus the difficulty and side effects that come with changing out the suspension.
- By the way, if you are into lowering or racing your car - then I would definitely recommend this kit - As you can really tune the car to what you want.
