Description
Best performance stock pistons for MINI that have a possible compression ratio of 10.0:1. Current pistons differ from the 60s originals, improved with a "low drag" slipper skirt design and a shorter lighter wrist pin. Wrist pin height is 1.5276", top dish is 8.4cc.
Performance is enhanced by the use of 3mm oil rings and the smaller drain slot behind this ring decreases the risk of breakage.

Piston Fact File
Created: January 30, 2000
Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements. All have an 8.4cc dished top, but compression ratios are carried by changing pin height (Pin height is the distance from the top of the piston to the center of the wrist pin- see dimension "A" shown here).
