Q: What is Caster?
Caster is the forward or rearward tilt angle of your steering axis. For example, on the Model 3 Performance Multi-link Suspension the steering axis is relative to the placement of the upper and lower ball joints and their offset relative to a vertical line. So if you were to draw a line between the upper and lower ball joints and measure the angle of that relative to a vertical line through your hub that would determine your caster.

I installed these with the race pads.. The car is significantly better at stopping, the pedal feel is fantastic. One of the biggest addtional things I noticed was the decreased weight.. The wheels done thud as hard over bumps, and comfort setting now feels like actual comfort.. The wheels also...

Best bang for your buck upgrade for your Tesla. Unplugged Performance installed these a few months after I got my Model 3 and was an immediate and significant difference. Eliminated body roll and sway in corners and car stays so much flatter. The difference is significant and very noticeable. Such...

Installed the Unplugged Performance stainless steel brake lines on my 2025 Tesla Model 3 Performance and the difference in pedal feel was immediately noticeable. The stock setup wasn’t bad, but these lines made the brake pedal feel much firmer, more responsive, and more confidence inspiring —...

I've spent the past couple of months researching forged wheels for my '21 Model 3 AWD LR. I spoke with Shahar in sales/customer support at Unplugged Performance. His suggestion made all the difference. We decided on a set of UP-03 Lightweight Forged Wheels 19x9.5 +35 in Satin Black and Titanium Lug...

I installed these because with my previous set of UP lowering springs I really had uneven tire wear and it costed me a lot of tires.
Installation was easy and the products look high quality.
Let's see how the rubbers hold up.
For now I used the same length as the original arms but made an alignment...

Just what I needed to get rid of the adaptive suspension error now that I'm running an air suspension setup. Cheaper than the other option out there.

I always hated how my Model Y would sway side to side at high speed on the highway when the road conditions were poor, even with the coil overs I wanted a little more stiffness and this fixed the problem, now it feels more like a Porsche/BMW M.

I've covered innovation in the vehicle space for a long time. Mercedes Benz gave me its first ride in its first autonomous vehicle. BMW drove me around SXSW in the first i3 electric all week long. I wrote four books on technology, predicting with each decade-long trends. I have the first video on...

Was hesitant to purchase but after seeing my before/after alignment report I am so glad I did. For everything Tesla does well, alignment from the factory needs work. UP perfectly aligned my M3. Highly recommend this product if you are installing the dual rate lowering springs. Call and ask for Kirk...
