- —Innovative forging design and piston skirt provide maximum horsepower and torque
- —Features forged pistons, rings, wrist pins, and circlips
- —These high-tech piston designs offer maximum compression ratios, ultra-stiff strutted forgings, and titanium nitride-coated rings, which all add up to more power that is sustained longer
- —Each piston is E-Coated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation
- —GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression

- —Cylinder sleeves must be purchased separately.
- —Service intervals may be increased with Racer's Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.
