Both are amazing coilover options in my experience. I did a car with the V3 and all new SuperPro bushings front and rear as well as diff and power steering rack and I swear that car felt like a Lexus.

 

That sounds great how much adjustment did you have to make from the way they were set came from factory?

 

The Hipermax are very good coilovers. Especially for the price. I drove a buddy's mk4 and it handled amazing and was an extremly comfy ride. I'll be picking up a set when I go to coilovers.

If you decide to go the KW route, be mindful that it requires the OEM top hats and require a little center drilling. With that said, having a new or low mileage top hat set would be best with preserved rubber. I have installed a set on my buddy's car and they are really nice on my limited seat time. (I have the HKS HM 3's). I also would not hesitate on a set of HKS HM4's as they are geared just for what you are after, right out of the box. Like you, both these 2 brands of coilovers would be my top 2 preferences.

 

I did not know this about the KW 's especially about having to drill out the centers my car has 48k miles on it top hats look pretty good, such a hard choice when i have not rode in a car with either one.

 

Cannot speak on KWs, but had multiple sets of HKS Hipermax, currently on IVs. These have been great, though street experience only, no track time. Smooth ride and put the power down very well.

 

Supra Turbo - Any vibration or transient noise on the freeway like when you cross bridges at speed?

 

It would be difficult to comment with my current drivetrain setup where everything vibrates, but none that I have noticed from the suspension. This is utilizing the HKS tophats also. The coilovers have been adjusted to suit the required ride height and dampening to put the power down as effectively as possible with the rear 15s.

 

there is a big difference in price 2k for kw v3 and 1300 for HKS IV wonder why

 

I've never owned HKS coilovers but I have the KW v3's since Dusty's original group buy a few years ago. Like Patrick said above, it rides Lexus-like. One of my original comments still holds, that when I drive over tracks or any rapid series of bumps I just smile as it glides smoothly under control. Besides the comfort aspect, I find the overall handling to be excellent and would buy these again unless something new/better has come out since.

I know the KW v3's are adjustable independently for rebound and compression as well as ride height. I think the HKS's only have one dampening adjustment so maybe that explains part of the price difference.

 

You'll want to adjust them to your chassis and driving environment.

 

Nice to see you back here, Nick

Its been a while

 

Thanks for the friendly vibes, Mr. Ree. Just about every day I check SF to see what's happening but I don't post like I used to, mostly because it seems like it's all been said and done and my patience isn't what it used to be a half century ago ;-)

 

Don't the KWs lack the ability to adjust ride height at the lower collar? You have to adjust them up top, which also creates issues with spring height/rate?

After reading all available info i can find on coilovers in general it seems that the harshness comes from the top mounts and getting rid of the rubber for a solid mount.
kw's keep the stock rubber top mounts. In some of the pictures of the HKS IV looks as if they have a rubber peace in the center of the solid top mount which should help or stop harshness also
but the info sheet is in Japanese so i cant say for sure what its purpose actually is? would be helpful to know what it says in english.

 

HKS GT4 owner here...yes, the HKS coilovers have a small rubber "spacer" between the spring and top perch.

 

Steve that's vary helpful information cant believe i didn't see that my self and they cost 600 bucks more looking like HKS is making more sence now.

 

Yes, I can't believe a coil over that cost that much doesn't have lower perch adjustability. That's crazy.

So, what's involved with adjusting the ride height, can you do it on the car?

Good feedback, I'm on Tein Flex Z's and looking to go with something nicer and was considering KW, HKS and Fortune Auto. I didn't realize the KW's needed extra work for install.

 

The extra work takes all of about 10 seconds to do. It isn't a big deal.

 

The HKS GT4 can adjust ride height while maintaining preload. This can be done on the car very quickly in accordance to the limits seen in the manual link below.

Most coil-overs have only a thread body (Tein HA, KW and others). vs. thread sleeve on a thread body (Hipermax GT4). This was big deal for me coming the gixxer drew bilstein setup.
