    Not a fan of the OEM rear look of the Model 3. This got me looking back at my car every chance I get! Better rear downforce as well. Feels much more confident around turns at high speeds.

  2. zackfeldstein9 (verified owner)

    I’m obsessed with my Ascension rear fascia! Gives the backend of the Model 3 a much needed improvement while improving rear downforce. Changed the whole look of the car from the back and it looks incredible. Will never own a Model 3 without it- it’s such a major difference. Really makes your car stand out from the rest which is great. 10/10!

  3. David Schlessman (verified owner)

    Same as the fascia, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I love the dry carbon material and would highly recommend. I wish the diffuser fins came standard, even with a higher cost. With some DIY, you can make the air ducts in the bumper another place to eject heat, like if you had an active oil cooler radiator.

What our customers say
The pictures on the website does not do justice. the wheels look extremely beautiful. Kirk was extremely helpful, and coordination was amazing. My wheels are gloss black, not able to add a picture to the review if not would do it. I went with slightly bigger wheels 20x10.5 front and 20X11 back. ...
This brace was an amazing upgrade for my car. I added the UP rear sway bar first then the full UP suspension then this Strut Tower Brace. I feel this completed the feel i was looking for. The cars back end feels so solid while cornering and over the bumpys feels so solid too. A noticeable...
Tight on turns and soft on bumps--the mild springs seemed like the best option for folks who want to keep the vehicle as close to stock as possible while simultaneously improving the vehicle ride quality.
These are absolutely THE BEST brakes (https://www.instagram.com/p/CveWNmjvKwT/) They work flawlessly lap after lap with it's nonstop stopping power, they will last forever. Incredible value for money and Highly recommend to anyone considering using their Tesla for both track and street.
Excellent product from a great team with great customer service! The factory Model 3 Performance's suspension is rather underwhelming, so once you add the Dual Rate Linear Springs along with the Sway Bar kit and Luxury Suspension Kit it completely transforms the car! UP also stands by their...
These springs were the first real mod I’d ever done to my Tesla and I’m so happy with the way they turned out. They really complete the look on my model 3. And I was surprised to find you don’t sacrifice anything in terms of ride comfort by adding them. The only problem is that now that I’ve...
This is by far the best front fascia out there and its makes the Model 3 look so much better! It gives it a much sportier look and I get comments on it all the time. One of the simplest upgrades that makes a huge difference as far as the look of the car goes. Couldn't be happier with how it looks....
The Willans Safety Harness kit along with the Ascension-R Racing seat just arrived from Unplugged Performance (https://www.instagram.com/p/Cv8f-5cvDuE/) The 6-point Harness kit goes hand in hand with the design of the racing seat. It looks absolutely well made and high quality making it a must have...
WIFE APPROVED!!! I have a 2018 Model 3 LR AWD with the stock 18" wheels. I've always felt that the ride was a bit stiff and jittery with the stock suspension. Looking around for a solution, I came across coil-over kits which were expensive and I really didn't think I would need the adjustability...
Significantly improved feel from this suspension kit. Don't forget yo get camber adjustments and springs that make this suspension upgrade feel like a whole new car!
These wheels are insanely light and strong! And, they look the bomb! If I didn’t look while picking them up, I would have thought they are carbon fiber! The same spec as was originally used on the Bionic Phoenix Model 3 race car! I put in my fastest time at Buttonwillow on these wheels...

Perfect companion product for the luxury suspension kit. An absolute must have for those who modify the springs of their vehicle.
This Ascension-R Racing seat just arrived from Unplugged Performance (https://www.instagram.com/p/Cv8f-5cvDuE/) It looks absolutely well manufactured, high quality and lightweight making it a must have accessory on any Tesla going to the track! Looks stunning and well designed!!
I had my Coilovers installed by NV Auto in Hamilton Canada. They did a good job and I now have a great ride. After about a month of driving I went one step further and put new 18” rims and tires on. This really improved the ride and is is a joy to drive my Tesla again. Thanks unplugged...
Bought the shock and it works great. Definitely recommend for Model Y owners on limited budget.
I have a Tesla Model 3 LR but the rep at UP accidentally ordered the MY listing instead which is the same since both M3 and MY share most parts including struts. Purchased as the roads in DC just aren't very pleasant and combined with Tesla's stock struts, it's pretty horrendous. Delivery took...
Who likes shredded tires? Nobody! Fix the wonky camber on early Model S vehicles with this easy upgrade.
I purchased a set of these Sway bars along with a few other upgrade components for my Model 3 (https://www.instagram.com/p/Cv8c-F2PEYP) The sway bars improve the ride quality, reduced body roll making the car more rigid and stable. Installation and setup was easy, being adjustable is an added bonus....
