Wiseco / DP / Pistal Racing, all the way for piston choice. Iasa also make nice pistons.
wiseco is one we often sell, we have pushed the product to extreme levels and are happy with the quality. same can be said for DP, we are using DP pistons in a few customer engines, at extreme power levels, with no issues.
wossner - we wont sell them, and advise against using them.
our reasons from personal findings: no anti det grooves, no gas expansion groove, sharp edges, quality varies from batch to batch - no consistency with them. sometimes you see them, the crown design is reasonable, other times its horrific. but they are made to a price, and that price if often whoever is offering the cheapest castings at the time. on more than one occasion we find leftover swarf stuck in the ring lands from machining... not very good for a "precision" product imo, so not something we are able to recommend.
