^Don't even know where to start with this? A lot of conjecture, hearsay and some really bizarre bigoted statements about how the (Asians) Taiwanese don't know how to weld?!?!
The after market front coilover suspension is built/designed the exact same way as Tesla's. They are pumping these cheap front suspension components out by the 10s of thousands. To make some statement "Asian" dampeners are known to fail over time is ridiculous that use this method. Taiwan has some of the most advanced manufacturing capabilities in the World, and the leader of many industries, not just computer chips, but carbon fiber etc..I know this first hand with direct experience. They certainly know how to weld amongst many thousands of other things.
Not sure where/how Tesla is making there dampeners...or again, is KW/MPP dipping their welding/metals is special sauce like Tesla to make it superior and won't fail ever? Just not true any of this. This isn't the only design/manufacturer that uses this type of setup...never heard of any of them failing over the past 20yrs on many manufacturer brands.
Next, adjusting a divorced setup and lowering doesn't make your car hit the ground and smash your battery. Or lowering in general. Sure, you slam the car, that happens with any vehicle, not just Tesla. This is common sense.
Most vendors recommend about a 1.5" drop, MPP etc..as a recommended start, for track, you can easily go lower, but daily driving on typical streets...not a problem. I've had 4 people in my car with my current drop, never bottomed it out.
As an example, real world, the 18 stock aero wheels, I replaced with 20x9 with a .5" diameter increased radius, which would mean, with a 1.5"drop, I actually only dropped the vehicle 1" from the stock ground height to the battery/side skirt. It is still 5" approximately from the ground to the bottom. Never, even over speed bumps, being a cautious person already over things like this, come close to hitting the battery. Furthermore, a properly setup coilover and height/dampening adjusted will control any bounce of the car, entire point/benefit of coilovers rather just springs to help alleviate any issues like this.
But whatever.....people can think/do what they want. I'm just giving people actual insights and info of real world experience with Riaction coilovers. Some other than $$$ MPP or UPP, Ohlins etc...
Good luck everyone!
