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.

Been waiting for this part from UP since purchasing my coilovers almost 2 years ago and just perfect timing that old links are completely shot and this totally changed the overall feel of the car and reduced tension. Customer service is excellent and will be doing next upgrades with UP

Good retrofit for a known problem w early Model Y's. Delivery of the parts was very delayed taking nearly three months after order. The installation experience was fine and seemed to be professionally done, however two retention clips on the aeroshield were missing after installation and were...

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...

Got these coil overs installed on my model 3 performance, and wow what a difference. Not only do they outperform the stock suspension in acceleration and cornering, but they also just ride so much smoother. Highly recommend!

I got the FUCAs installed on my 2018 Performance Model 3 and wished I hadn’t waited so long to do it! Now I can do proper alignments with camber on the front, not possible to do with the stock control arms. You can also put custom wheel sizes with super wide tires on the front without worrying...

Purchased these beautiful lightweight aero wheels to give my Tesla a different look. I’ve only seen them on one other car and it was a Tesla cyber truck and they looked great rolling down the highway.

I love these brakes!, quiet, smooth, and never fade regardless of how aggressive I drive, after a few sessions at buttonwillow still strong, going to save so much money over replacing my iron brakes constantly (I went through 3 sets of pads and rotors tracking). Ultimate confidence that was...

This product was great! Paired with the upgraded brake fluid, this helped the brake pedal not feel as spongey and gave me confidence in the OEM brakes. Thanks Unplugged!
