Review on Adjustable Tapered Piston Ring Compressor - Checkered Flag Performance, 3.940" to 4.060" by Andrew Schobinger

Revainrating 3 out of 5

Doesn't go down to 3,900.

Minimum size was 3.953 not 3.900 as described - had to remove 1mm from one edge to reduce diameter to fit 100mm Porsche 944 pistons. Worked very well once the modification was complete, so the tool really matched the description.

Pros
  • Great fit for me
Cons
  • Functionality
