I'm gonna get one set coilover,I'm thinking about the type Flex and the Hypermax II...I hav friends who use the Flex,I have testdrive it.That is a pretty good coilover on street even track....But I hav heard that the hypermaxII is pretty good also...But I never try it...I want to get something different than my friend...Will the hypermax II running comfortable on street.Can anyone tell me How much will it be???bcoz I can't find it on HKS US Web..Thanks

 

im running the hipermax RS and those were designed to be more street-able. the ride quality is top notch. you won't regret them. also deedubb is running the hipermax II on his car. a bit more stiffer then the HKS RS but they are very streetable plus awesome at track events. with 30 way adjustable dampening its awesome. being "bias" but i'd go hks hands down.

 

go with hks, you won't regret it...

 

tien flex aren't even monotubes...they're cheap for a reason.

I've always liked HKS, even before I got my rx8. I've bought alot of their parts, and never once been dissapointed, not even about the price.

now I just need to get them to sponsor me lol

 

me too, i need to get sponsored by them too!

 

wats HKS mean? ( sorry off topic)

 

aftermarket parts manufacturer for japanese cars (mostly)

www.hksusa.com or www.hks-power.co.jp

 

The HKS RSs arent height adjustable are they?

 

HKS stands for the 3 founders of the company:

H-Hasegawa, as in Hiroyuki Hasegawa.

K-Kitagawa, as in Goichi Kitagawa.

S- Sigma, as in Sigma Automotive Company, Ltd.

Hasegawa and Kitagawa formed the company with the assistance of capital infusion from Sigma Automotive, hence the name HKS...

 

Yes the RS's are height adjustable, the dampening can be adjusted as well.

 

^ diddo on what deedubb said

 

Height adjustments on the RS affect spring preloads though right?

 

i was also thinking of these two coilovers and i heard many good stuff about the hks
but then again... tein has the edfc... hmm...

 

edfc is just for convenience. its not a necessity. just pop the hood or the trunk and change it.

 

all i do to stiffin is pop hood, and turn a ****. it takes literally seconds to do. same for the trunk. i'd rather have quality and great coilovers over a button for that

 

the tein flex are not poor quality by any means. id say both companies make great products and your choice will mainly depend on your purpose and budget. both are streetable and trackable. unless you race competitively, you wont likely notice a big difference in handling. furthermore, if you dont race competitively, monotube should not be a big factor in your decision since you likely wont even notice that either.\

if this is mainly for street with some track time, either Tein Flex or HKS Hipermax RS or Hipermax II will be fine. comparing these objectively, i believe the Flex cost a little less, and also have higher spring rates than both HKS sets

 

i didnt mean anything that flex were poor quality. i just said it in a way haha. but yea nicely written. =) still go for HKS hahaha

 

I am probably going with the Hipermax RS's for my next round of modifications on my car. Because I just haven't done enough to it yet.

 

thanks :p its all g

i am wondering though, how important do you think the spring preload adjustment is? the tein flex have this, but i notice many of the top coilovers like HKS, FEED, RE Amemiya, all do not.

also wondering, how is the ride "comfort" for daily driving between Tein Flex, HKS Hipermax RS, and Hipermax II?

 

I got another question,I hav heard that the hypermax II is make for the Japan only.That's why they don't hav it on US HKS web site...Is that True???If it is ture,will they perfect fit on US RX8???

 

On the Hipermax RS/IIs I believe you can adjust preload, and the adjusting the preload on the RS will affect the ride height (vice versa). Whereas on the Hipermax IIs you can change the preload and adjust the ride height independently.

My question is how does corner balancing with the RSs affect the preload/performance?

 

The fitment is exactly the same. The Hipermax RS is basically a Hipermax II that was re-valved for a slightly softer ride (harsher road conditions like the U.S.) http://www.hksusa.com/products/more.asp?id=1991 http://www.hksusa.com/info/?id=2838&rsku=0. This is why HKS USA only stocks the RS for the RX8. If needed, the Hipermax II or Hipermax Performer (adjustable pre-load) can be special ordered from Japan.

I hope this helps!

 

with some help i just realized something... all coilovers have a preload adjustment, not all coilovers have a shock body adjustment. for coilovers without the shock body adjustment, changing the height and preload are done with the same adjustment. therefore, if you want to go low on the Hipermax RS, you will have no preload at all! this means the ideal high must be somewhere where the spring is loaded. so my new question is, how low will the car be when the preload is set just slightly?

also, it was my understanding that Hipermax II also do not have the shock body adjustment so adjusting the height and preload will also affect each other...

 

Don't worry, the Hipermax RS is designed to go as low as -72mm Front & -80mm Rear (from stock height). Not even Lazi or XDEEDUBBX's car is set-up that low! hahaha FYI- They come preset from the HKS factory at -47mm Front & -33mm Rear.

 

Here's a side pic of my car, it's not set too low but there's still plenty of play:

I've got the Hipermax II's
