There are detailed reviews of these on this forum, people complaining about squeaking noises, dust boot not fitting, bump stops needed to be cut. And all these review videos are by people who stand to profit from selling them. I'd be cautious if I were you. $600 is so cheap, there are bicycle shocks more expensive than that!
Thanks for your help.
I will proceed with caution. And I have a question for you.
This isn't my first rodeo. I've installed many shocks in many vehicles since the 1960's.
I installed high performance Koni's in a sports car I drove in the early 1980's for "street" racing. I also installed "racing tires" on that car, and I custom modified the suspension for oversteer. I've installed many shocks, like Fox shocks in high performance mountain bikes. Yes, very expensive. I've done all the work myself.
The dust boot doesn't fit well, not such a big deal IMHO. As one reviewer said, if they last 50k miles I'm so happy. IMHO, for me, if they last 25k miles and do the trick, I'm very happy.
The bump stops are not required. Cutting them is optional. These Tein have internal bump stops. The external bump stops are back up, so to speak. So I can decide on that when and if the time comes.
Read the review by the guy here too. He goes into great detail.
Most of the experiences didn't have squeaking, that was just one or a few. I think he later found the problem.
I don't want high performance for racing. I want exactly what this cheapo set promises according to rider experiences. Just a somewhat softer ride and some smoothing out of rough asphalt tire vibrations. I measured around 100 hz. Looks like these Tein Shocks can do that. Keeping my stock springs will preserve the ride height.
Shock swaps are not that difficult unless they are McPherson struts and that just requires a spring compression kit. I've done them as well.
If they don't work out well, I can always swap back or swap in another aftermarket set.
I'll consider another name brand if they don't make the suspension stiffer and more prone to more impact and more vibrations.
I'm just getting started in my research of shocks.
If you know of a specific set of shocks made for the Tesla Model 3 that accomplish those goals, I'll have a serious look at them.
I haven't pulled the trigger yet. I'll be trying a number of approaches in addition to the many I've already implemented.
What's interesting is that I found pretty good improvement with 10% psi reduction. That gives me some hope and some information.
I'm going to install my last go at sound absorption tomorrow or later this week. I just sound dampened the trunk lid today, in addition to all the other work I've done and reported. I'll install the last set of materials and drive for a while. If it still bothers me enough, I'll dig deeper into shocks...and tires. Shocks make logical sense to me. The wheels are vibrating at a certain resonant frequency on certain surfaces. Lowering pressure changes the natural oscillation resonant frequencies as do shocks. A different shock build would behave differently. Based on the verbal comments the Tein hold some hope in that way.
I do have a question for you, as you seem to be informed.
Tire Rack told me that summer tires vibrate more than all season and recommended a brand new product by Bridgestone for my EV.
I see that COSTO also sells them and a lot cheaper. When I need to replace tires I want to be armed with info.
Do you think that Tire Rack is correct? That my stock OEM summer tires vibrate more than an all season EV specific tire?
I had not heard that previously.
Thank you,
George
