HKS Hipermax IV GT Spec 20 review

I drove my car a couple of days after fitting this coilover kit, and these are my first impressions.
I come from PP Sachs dampers with JDM STi springs; the kit has been fitted with shipped F16/R17 mm lowering and 15/30 click setting; front camber was set at -1.5 degrees.
Hydraulic is wonderful, comfort is the same of stock suspensions, or a little more, as this is not as harsh as Sachs, rough roads are silky smooth but there is no buncing.
Car is very flat, a little too much for my tastes, perhaps 4kg/mm springs would be better. Much more traction, less oversteer (finally!), drift is much more controllable.
Camber plates are useless, 1.5 is almost maxed out, and they transmit big bangs on the chassis when hitting big potholes. Very annoying to adjust. But this is not specific to this kit.
The only doubt I have is the front excursion, that is declared as 87 mm.
This should be good, but I think I bottomed out a couple of times...
