Installed this on my CyberBeast in my own garage. The instructions provided were top notch with outstanding attention to detail. I installed the bar in the middle position. On the first turn I noticed the decrease in body roll. The turn in and mid turn stability is much improved. I am very...

These are a great set of wheels. I purchased them to replace my OEM 2024 M3P wheels. I went with the 19x9.5 in satin black. The wheels are very lightweight and durable. I wrapped them in Michelin Pilot Sport 4S summer tires. The wheels are great on the street for daily use and I have used them at...

The sway bars are phenomenal. I installed these in my 2025 model 3 performance. I already had the moderate lowering springs from unplugged and after adding the sway bars and the end links made a massive difference. There's barely any body roll and the car feels more planted even when heavy...

I purchased the entire suspension front and rear adjustable, and fixed spherical bushing arm sets, along with the rear sway bar for my 2022 Tesla Model S.
After the complete UP installation, and spec alignment, the car is a different Monster. Not only it is firm and stable at high speeds, but...

I have both the rear camber arms and the rear toe arms together making the rear alignment easy and quick to change. I adjust back and forth between street alignment for daily commuting and autocross race alignment for race day. These are easy to use and the settings are very repeatable. Customer...

50mm spacers are exactly what you need to give your CyberTruck the stance it was created for!
By a skilled installer all 4 spacers installed under 45 minutes.
2000 miles on them and no wobble!

I've just transformed my Cybertruck into an even more formidable beast, and let me tell you, this is the upgrade you didn't know you needed until you see it.
The installation was as straightforward as it gets - a quick clean with alcohol, peel off the tape, press, hold, and voilà! It was like...

Took me about 2 hours total to remove the arms press out the rubber bushings and press in these then fit back to my 24 performance, very direct steering now and drastically reduced the wobbly feeling under hard braking , slightly more road noise over rough roads but if your looking for race car like...

Added these high quality RAC arm set to the D&S PRO coilover suspension lift kit. The ride is amazing after installation and alignment. Highly recommend.

Wanted an upgrade to the stock suspension that allowed maximum versatility for traversing truck trails towing a camping trailer as well as providing comfort for daily commuter driving. Called and spoke with Kirk Nason at Unplugged Performance in Hawthorne, CA and ordered the D&S PRO coilover...

Tesla will just replace the entire control arm, with THE SAME inferior rubber bushing. Was happy to find these UPGRADED bushings to solve the problem for good. Excellent customer service as well.

I purchased the Up03 wheel setup for my Model X Plaid in 20x10.5 square. Coming from the stock 22-inch wheels, there was a massive improvement in weight savings, and the car feels more responsive with superior ride quality. I’ve also noticed a significant increase in range. My sales rep, Kirk, was...

Tesla Model 3 UP-05 Forged Wheels (Set of 4)
RATED 5.00
The UP-05s from Unplugged are a game-changer for my Tesla Model 3 Performance. These wheels have transformed my ride, making the car feel incredibly nimble whether I'm zipping through a Taco Bell drive-thru or carving up some twisty country roads. The aesthetics are on point - these wheels look sick...

One of my favorite upgrades to the Model 3, allows for fine-tuning of the entire suspension system to balance the car out. Each notch makes a noticeable difference, so certainly flexibility with the settings. I started with Medium/Medium settings and tuned them according to the car's handling.

Beefy design, necessarily. Need the toe arms in conjunction with rear camber arms to dial in toe at the same time, otherwise toe will be out of spec when adding negative rear camber.

Installed traction and trailing arms on 2024 Model 3 Performance, keeps the rear end more stable, especially on hard acceleration and deceleration at the track.

Real cool suspensions the car drives smooth and quite. Made a real difference to the drivability and now I really enjoy driving the car. Absolutely recommend it if your factory shocks have failed. Mine failed in 5 years.

Tesla Model Y Luxury Suspension Kit
RATED 5.00
My 2021 Model Y performance rode very harsh and bumpy. Like the suspension bottomed out on every pothole. I did the suspension upgrade and it’s a HUGE difference. My car rides great now. It handles the potholes no big deal now. I wish I had done this three years ago when I got the car. Sandy...

HIGHLY RECOMMEND THE SPORT PRO COILOVER SUSPENSION KIT. SUCH A GREAT PRODUCT. MUCH BETTER RIDE THAN STOCK. FEELS LIKE I’M DRIVING A SPORTS CAR AND LOOKS AMAZING! ALSO LOVE THAT IM ABLE TO ADJUST HEIGHT AND DAMPING.
THANK YOU ANDREW AND UNPLUGGED PERFORMANCE TEAM.

Should’ve been stock with all teslas, combined with a stiffer set of aftermarket coilovers, the car handles insanely well. I purchased this front and rear sway bar set along with end links for a standard range model 3. It makes such a huge difference, the car feels more planted especially entering...

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.
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!
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.
