Not the best
Good quality, easy install. They squeak over bumps which sucks. Stiffer then stock as they should be. Within a month, the damper adjuster fell off somehow... also it sucks that its on the bottom. I don't recommend these as other coilovers for the same price are probably better.

I'm sorry to hear this! Traditionally HKS has been pretty decent. I'd suggest trying the Silver's Neomax. A nice upgrade, for your wallet as well.
