      Amazing! Bought these along with the Unplugged Performance Competition Track Brake Pads and the results were incredible. Took my 2022 Model 3 Performance to Tesla Corsa with these installed and the difference was instantly noticeable. No more mushy feel when the temps got high. Brakes felt solid....

      These carbon fiber seats are amazing in our plaid drag car. Looks like it came from Tesla just like that. ??? Thanks

      These brakes perform great and I should have upgraded to these a long time ago. Pedal travel with with the included brake lines are much improved as well.

      Great complement to my Model Y's coil overs and sway bar set up. Significant handling improvements overall. Best of all, these camber arms give me the peace of mind of not worrying about uneven tire wear after dropping my ride height 1 inch. Car looks and feels great on the road.

      This spoiler has a perfect balance. It isn't as subtle as the OEM performance Teslas, yet not comically large. A fitting addition to the Plaid! Great design as is to be expected from Koenigsegg. Slight efficiency gains at high speeds as well.

      Finally!!!! Been waiting on UP to both have a decent Black Friday sale and to have this item on it and whatdoyaknow…..HALF OFF! I wish it was all gray everywhere, but I’ll do the touch up myself and get it 100% how I need it!!!

      Great quality shirt to represent only the best.
      Christian N. December 18, 2025
      Purchased these with the luxury coilovers but kept things at stock ride height. So far, everything is great!

      These wheels deliver. I've been looking for wheels that look good and can maintain efficiency. These wheels hit both marks and have the added bonus of durability.
      Cory O. September 30, 2025
      After lowering my car I had some bad rear tire wear because I wasn't able to get a good alignment with the stock arms. This was a quick and easy fix :) 10/10
