I have both Ohlins and HKS Hypermax IV GT though on different cars/platforms.
I would only recommend the HKS IVGT if your doing less than 1-2 track days in a year and the car is a daily driver. But, HKS offers the Hypermax IV SP for track use for a good reason. If you do a fair share of performance driving the Ohlins Road AND TRACK will pay for themselves in smiles. The IVGT can absolutely be used on the track but, once you start to adjust it up your going to notice a bit more trade off you wouldn't with the Ohlins.
Pros for the HKS HPIV GT
-Half price.
-Include camber plates
-Longer Service/Rebuild Intervals
Pros for the Ohlins Mi20
-A much better ride at both ends of adjustment
-DFV's ability to soak up potholes and bumps is a huge plus
-Big USA location making rebuilds a bit faster. (I do believe HKS now too has a usa location)
That being said I've never regretted either coilover. I don't kid myself and call my fatass EvoX a track car. So having the extra $1200 to spend elsewhere on the car to improve my car's quality of life (read more hersepwrs) was well worth it. And on my BRZ ts, I could never forgive myself for putting anything but, a great coilover on the car that actually an improvement over the factory tuned sti suspension.
