      Moto Miwa definitely made the right recommendation for the Moderate Lowering springs for my Model 3 Performance. They gave it the perfect balance between drop and functionality - good ride quality and no scraping. Also, in another conversation regarding tire wear, Moto suggested I purchase the...

      As part of my UP order, which included the Model X Sports Dynamic Lowering Kit, I was advised to get a set of rear Camber Arms so that excess camber could be removed from my rear tires. I was experiencing inner edge premature tire wear, due to Tesla setting to much negative camber out of the...

      After using the fascia for over two years, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I would recommend epoxy over double-sided tape to secure the ultrasonic sensors for a longer-lasting, flush fitment.

      I installed the Unplugged Performance UP INVINCIBLE® HD Rear Bumper with Hardcore Trailer Hitch Receiver on my Tesla Cybertruck, opting for rear rock sliders and LED flood lights, no swing arms. This thing is a beast! Built from tough A36 steel with a sleek black powder coat, it’s perfect for...

      I received the lower compliance Aft arms today (fri), after ordering on mon. I wasn't sure I'd have time to install, since I already had a lot on my plate, but this afternoon I had a couple spare hours, it ended up only taking about 45 min, including getting the Tesla on jack stands. my...

      The "Road Warrior" Curb Guards work as advertised for the most part. I did not find them to be as "protective" as advertised in all the Youtube and promotional videos. Just a day after I installed my Road Warrior wheels, I hit a curb while turning at a slight angle. This damaged the curb guard as...

      Ross is the most awesome - extremely helpful in the purchasing process of this BBK - not only I got in red, Ross was able to build it without the logo, send me custom dry transfer decal for me to have a full custom look. This brakes stops radically better than OEM. For a car as heavy as the Model X,...

      This definitely helps cool down my drive unit quicker. I'm able to run a hot lap at the track, then a single cooldown lap to bring the drivetrain temperature back into the green. It was awesome seeing it cool down within a lap at Buttonwillow.

      Dominic Marcu - Racing Driver perfect! with their help I can have the desired setup for the competition car.
      Dominic M. April 12, 2023
      Coupled with the FUCAs, the rear arms really help do a proper alignment. Definitely get these if you want to get a perfect alignment for your car, and better than OEM. I put -2 camber in the rear for my track day yesterday and achieved phenomenal handling in the corners. I also tried it out in drift...
