Toyota Corolla GTS and Toyota MR2 are on the line of the high-performance Toyota sports car and no doubt the machine under the hood has a lot of power. As engine rpm rises, valves must open and close in a shorter time and so requires stronger Valve Springs in order to apply sufficient pressure. When changing to high lift cams, proper contact between the valves and the cams can be lost which leads to valve float. HKS Valve spring uses the highest quality materials, heat treatment, and shot-peening to create a high durability spring with low inertia.
