Customers praised the product for its high-quality material indicating its heavy-duty nature and great fit. Its sleek design is appreciated for not interfering with the frame. The product received commendations for practicality, as it comes as a ready-to-install kit, usable on either front or back, and including all hardware required. It's particularly recommended for metric cars, and for lightweight vehicles where it performs exceptionally well. Be sure to check the fit with the tech department before ordering. Some users reported concerns with slider bolt installation and missing parts.

Calipers are nice can be used on front or rear. Streamline enough to not interfere with frame. The slider bolts were hard to install kept hanging on the seals, had to use the type with the sleeves.

Installed for use on 50's era spindles and everything worked out as expected. Definitely follow the guidance videos found on Speedway for solving the interferences you might encounter. Not too difficult and very happy with the outcome.
