SuperPro Front Lower Control Arm Kit | 2016-2021 Honda Civic (TRC1030)

They wont let me leave a 2-star review...
So I'll try this.
Shoddy product. Overpriced junk. Yeah, they were stiff, etc. But sucked on a daily in Austin. Forget going down dirt roads. Definitely for track use.... but no, not really. Look at the pics. The arm was popping out of the rear bushing. The company who owns SuperPro (and Whiteline) did refund me.

A vastly noticeable difference in cornering, very stiff feel in the steering wheel, the car felt firmly planted. The ride was extremely rough, and loud, compared to the OEM rubber, which is the point – handling vs comfort. After a while, they would creak when it was cold and driving over bumps. If my civic was a track car, these LCAs would be alright. I enjoyed these at first, they became problematic on a daily, driving around Austin and multiple road trips to Houston – absolutely horrible on dirt roads.

BUT THEN

The passenger side began to pull out of the compliance bushing. It was only the passenger side, and after many failed attempts, I was able to warranty them.

Zender, the parent-company of SuperPro and Whiteline, was willing to refund the purchase in it's entirety even after the LCAs were installed for a few months – thus the two-star review over a one-star.

This was in 2023, and Zender's representative did let me know they were aware of the problem and working on a solution. However, they continued to sell these.
Great customer service, shoddy parts.
