HKS just released the hypermax racing sport coil over kit for Nissan 350Z not long ago and we got a whole bunch of these in stock. These are the best coil over you can get under $2000 !!!!

It comes with 30 way dampering and rebound adjustability (simultaneously), single tube with an oversized piston and dual oil and gas chambers. It also comes with front adjustable pillowball mounts and dual rear helper spring.

Nissan 350Z - $1599

 

still more available !!!!

 

Do you have any more information about these? Spring rates? Height Adjustable rangee? etc?

 

6 kg in the front, 4 kg in the rear. Front -45mm from stock and rear -31 mm from stock.

 

I swore I'd never post here again, but I'll make a exception.

Not posting this to belittle or make anyone feel wronged, just posting to correct a honest mistake before it's taken as gospil.

The above spring rate info is not correct, I knew it couldn't be, oem is 5.6Kg/6.1Kg. I just called HKS and while they don't normally give out rate info, when asked if the above rate info is correct, HKS's reply was "no, the Hypermax RS for the Z33 use's spring rates of 8Kg/8Kg".

Anyone that is worried about repairing or revavling a HKS coilover should know that they will have a US center online by the end of the year, so that work can be done here vs sending them to Japan only.

The Hypermax II is sprung slightly stiffer at 9Kg/9Kg and use's more aggresive valving then the RS, which you wouldn't think reading the text that describes both products.
