3 reviews for Tesla Model 3 Ascension Rear Bumper and Diffuser System

  1. Andrew Petrella (verified owner)

    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
I purchased these in conjunction with the luxury coilovers and couldn’t be happier!
Got these with my order of Moderate Springs and Street/Track Sway-bars and they do what they are intended to do. Got my alignment darn near within spec which will help with tire wear. I haven't had them for long so I can't comment on durability but they sure are built sturdy as hell. If you are...
Got the Street/Track version for my 2022 Performance 3 and couldn't be happier with them. I combined them with the Moderate Lowering Springs and this combo is perfect. The turn in is quicker and with the reduced body roll it makes the handling now better match the acceleration abilities of the 3. ...

Had the bars installed with the end links on my M3P, at the same time lowered with performance springs and got new tires. No regrets. The car rides flat af. I look forward to round-abouts now. Big ups to UP.
I purchased these as set with my coil overs and these are definite must to install. These bushing add great handling to your steering. Steering is more accurate and responds well to the drivers needs. Highly recommend!
My 2019 Performance Model 3 is great, but with the heavy weight of this EV the cornering at high speeds was disappointing. I recently added these Dual Rate Lowering Springs to the UP Sway Bars, and the handling is definitely getting better! The initial spring rate makes the bumps less jarring with...
Shout out to Andrew at Unplugged Performance! Customer service is excellent. Great communication with everything. Knowledgeable about all products. Will do more business with UP.
On the track or not these sway bars make your car feel solid on turns. Immediately I noticed improved corner turns which is great! Highly recommend!
LOVE my new UP-03 wheels. Super light, super strong and they look so good. Super high quality finish on the wheels too, worth every penny. Have had the wheels for just a few days and have gotten tons of compliments on the road and at the track. These are the best wheels you can buy for your Tesla,...
Paint match was perfect. Fit is perfect. It’s exactly what I was looking for, exceeded expectations.
If love carbon fiber like I do then this is a must. Nothing compares to UP carbon coaster. The weaves are super clean, very sturdy, looks great. I couldn’t help myself and got this to add to my carbon collection.
I wanted to wait a few weeks before leaving my review to really see if there was a significant difference and it is a significantly better ride. I commute 70 miles a day on a fairly rough socal highway and the change is noticeable. Yes, you’re still going to feel the bumps but they are not as...
Excellent product! I installed mine as my first step into getting some more performance out of my M3P for Autocross. The front and rear sway bars along with some wider wheels and stickier tires really took my lap times to the next level. I would say, if you drive hard with these sway bars like I...
I have my model 3 performance and love it and now after adding these coil overs, can’t comprehend why these aren’t stock for tesla. These coil overs are amazing automagically felt like the car was on a cloud, handles great, and very smooth. Noise is reduced and can not believe I took this long...
Oh, wow; it is insane that one bar can dramatically alter the dynamics of the car. It is so much more planted and stable during those freeway maneuvers, which was the primary reason I bought the bar. The car is just solid at all speeds. Really solid. What is shocking is that the comfort levels seem...
Got these with my order of Moderate Springs and Street/Track Sway-bars and they helped reduced the offset tension of lowering the car. Great product and thank you Blake (from customer service) for answering my questions. Unplugged has been a great company to order from, top notch for sure.
Received my suspension for my Y 2022 long range what a difference. Set it for 8 on the adjustment rides totally different what a great job took it to a friend of mine Frank Reyes to install Desert car medics said the product was very well made installed it in about 5 and 1/2 hours. Driving it for a...
These are exactly what I was expecting. I waited over a year for them. Pandemic backorders and all. It took me about 6 hours to install with help from a friend. The fronts were the worst part. You have to have the spring compressors mounted just right and really compress them a lot to assemble the...
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.
My 2022 3 Performance was a monster truck in stock form, wasn't pleased with the look or the softness. A car of this caliber shouldn't look this way and thank goodness Unplugged had the fix. I got their Moderate Springs and they are the perfect amount of drop to daily the car. They eliminate the...
