Never heard of that HKS setup til now. I looked them up and HKS G are a spec strut/spring combo sold together
link here
Couldn't find hands on feedback but HKS looks to have valved the shocks for the spring rates. In theory those should ride great, I could not find anything on the site indicating ride height. Probably closer to stock with 2.9K front springs and limited bump travel. Yellows have a 4.5K front by comparison.
Whether they would ride better than say a yellow/B6 setup is hard to say. Would be an interesting comparison of anyone lives near you with yellow/B6 should you choose to go with the HKS.
