Review: HKS Hipermax IV SP for 370Z

Stright_Drop

How do they feel about true type coilovers vs oem type for the z34? Also do they offer any true type coilovers for the z34?
Thanks

Isn't that nearly impossible? Difference in driver's weight can upset the corner balance. 150lbs driver versus a 250lbs driver can make quite a bit of difference. The right and the left coilovers did not come set up in different heights, so I doubt that they are corner balanced.

If you're talking about Front/Rear weight distribution, out of the box, the coils were set up with 689mm front, 690mm rear. But again, since the driver is no located in the dead center of the car, driver weight can change the front/rear distribution also.
FYI, I'm running F:669mm R:657mm, so I would've shifted the weight toward the rear with my current set up from the out-of-box setup.

Are the HKS Hipermax IV GT coilovers corner balanced out of the box? | HuffPost

This example doesn't take into consideration driver weight or asb endlink alignment. Either factor can change the cross weight by 2-5% easily.

But for an out of the box cross weight of around 50% this is a decent range but not untypical, certainly if its a true coilover kit and preload is preset. This is much harder to do with a divorced spring in the rear unless the perch was preset evenly.

I stand corrected, sir! I spoke with the HKS engineer in Japan, and he said they make the best effort to send out the unit with the settings that's close to being balanced for the front/rear distribution of the weight. Obviously, those concerns I had applies, and the car will not truly be balanced, but it would be a good starting point.

The out-of-the-box setting was rear being 1mm taller as far the ride height goes. I'm running about 4mm shorter in the rear instead. So, I may have a little more weight in the rear than their "balanced" set up. But I'm not exactly the smallest guy either at 195lbs, so by accident, I may be close. :-)

Thanks for inquiring with the engineer and good to know that these come so well setup from the factory.
