KPMI® performance valve spring kits are modeled using cam pro昀椀le and simulation softwares. By utilizing FEA software, it was possible to take advantage of the
increased strength and wear resistance of a heat treated steel retainer, while reducing its mass to within grams of a comparable titanium retainer. With 65lbs of
seat pressure these kits are the ultimate setup for any Busa street/strip tuner.
