That's a steal for those evo 9 springs/retainers. I've ran them on most of my high hp builds without a single issue.

In case anybody was wondering, the stock DSM retainer = 15.2g, Crower CM = 8.5g, Stock Evo 8 3.98 grams! That is weight that the spring does not need to lift every single valve event. Considering an 8k RPM pull, that's 40,800 grams or 99 pounds worth of weight the spring does not have to contend with.

Great find Halon!
