Wiseco has been manufacturing competition pistons for over 35 years. Given their excellent track record of quality and reliability, we decided to make Wiseco our preferred piston.
VAC pistons are custom made by Wiseco to meet our specs and requirements.

Strongest pistons available
Consistent tolerances to within .0002"

Pro Street Tuff Coat is a service we provide now for any piston purchase. We take your
pistons, teflon coat the skirts to prevent piston scuff and thermo coat the dish to deflect detonation and
prevent any piston shrinkage / melting. We have run these pistons on several street cars, as well as in competition
and we cant say enough about the advantages of running this coating.
Simply add "Pro Street Tuff Coat" option to your piston choice and we will have your pistons treated before
they are sent to you.
these are some great pistons, currently using the 81.5mm 9.0.1 comp. in my b16, and they are great, perfectly balanced sets, rings came pregapped for direct, install, complete, spec sheets and installation guide, and recomended useage. A+
rudebuoy reviewed Wiseco Pistons part # WI-K542M815
Purchased Wiseco (with compression ratio of 10.5:1) because they have the highest all-round performance ratings and remain competitively priced. Looked at Arias and Ross pistons but they do not compare favorably.
sunmind reviewed Wiseco Pistons part # WI-K570M915
Since my first review, was contacted by Wiseco. They offered me a custom set of forged pistons with milled skirts, offset pins and domed-crowns to give a compression ratio of 10.7:1. Top notch service
