Hks Hiper D (hiper Damper? Drift?)

[Yawn]

Hey guys i recently acquired a set of HKS Hiper D's with buddy club springs on the rear which are approximately 8kg (dont know the proper unit for it). I plan to fit it to my 32, but the thing is i actually got them by mistake, assuming they were Hipermax II's. I have never took my car to the drags and i dont really plan to, my main focus is on circuit racing. I dont plan to join any competitions or the like, just a track day every month or 2. I know the Hiper D's have been developed for the quarter mile, with retarded dampening mainly on the rears. I also understand that this will give the car a funny feel while on the limit, with the suspension having a laggy feel to it. However, I dont really have the finances to buy another proper set now that ive got these unless i sell them.

The thing is id rather keep them for my own use IF they will give me a reasonably substantial upgrade from the stock shocks while on the track. What do you guys think? Not even worth trying them on at an upcoming track day? Will they instead hamper my performance on the track? Or maybe a rather good set, obviously not as good as a set of Hipermax II's, but still some good suspension overall and still worth using? I know this is all my own fault but any help or opinions are highly appreciated.

Cheers guys

I'm fairly sure that the Hiper D's are aimed at drifting and the ones aimed at drag are the Hipermax Drag. Should definitely be better than stock suspension, maybe a bit oversteery?

Eh? Really? Hmm.. How come I cant find much info on it anywhere? :S

Also, which are the rears? The longer ones? The fronts are the onse with bigger pillowball mounts am i right?

If the above is right that means the fronts have got higher spring rates (ie. harder than the rears) and the rears have got progressive hks springs. Does that sound like a drift setup? I personally thought that sounded like a drag setup but i know nuts when it comes to suspension heh.

Yes the longer ones are the rears. Usually you will have stiffer springs in the front for FR cars, as there is more weight in the front to hold up. From what I've seen, the HKS progressive springs incorporate a helper spring which completely crushes down with the weight of the car on it. It is just there to keep the spring trapped at full droop.

If you want to tell if it is a drift or drag setup, go have a look at the measuring spring rates thread. Measure you're springs as per the thread, and post the measurements there, Gary will work out the spring rate. Drag setups have spring rates around ~4/3kg/mm, where as drift setups have much higher spring rates (usually at least 8/6kg/mm)

Cheers mate, just checked, theres certainly no helper springs beneath the progressive springs. I just did my own shitty measurements, using a crap ruler, but i tried to be as accurate and careful as possible, and after that did the calculations on http://www.proshocks.com/calcs/coilsprate.htm that i found from that thread. I have no idea how to measure the progressive springs spring rate, but the fronts are roughly 5.5 kg/mm, albeit not hks springs anymore, their buddy clubs. Sounds like the fronts have been set up for circuit to me, no idea bout the rears tho. From what I think, the fronts were softer before and the springs were changed to ones with higher spring rates, what do you think?

Cheers for the help so far

Oh and update, I was looking around searching for hipermax D's and they look nothing like what i have. The lengths are totally different and hipermax D's have this special mounting thing on the side, which I doubt is car specific. To tell you the truth from all the pictures ive seen, mine looks like the usual hipermax II's the most, just that the pillowball uppermounts arent anodised purple, their just normal silver and the fact that my set has stickers on the lower part of the suspension that clearly say hiper d. But could it stand for hiper damper? It looks like the whole range of hks suspension has that exact same sticker tho. However, I cant confirm what any of those stickers say (besides my own) coz their too small. Can anyone with a set of HKS suspension advise?

Cheers
