Hi all, i've been dabbling into getting an entirely new suspension setup and have my eyes on the HKS Hypermax 2 coilover kits. My ride is an R32 GTST with an RB25DET running a GCG Stage 2 450HP turbo, etc. A mate of mine has an adjustable HKS setup (not Hypermax an older version) which is probably the best handling setup i've ridden so far in terms of a street car. I'm currently running non adjustable Nismo lowered springs and Bilstein shocks. This is fine for the street and quite comfortable...not too harsh at all. I also have a set of aftermarket Jap springs (no idea what brand) that pretty much give me neutral chassis balance in corners. With the Nismo springs i have quite alot of body roll...handles like a whale. The jap no-name springs however bring the ride to borderline annoying and very stiff (probably more suited to track...and makes my car lowered to the shithouse).

I know HKS make a Hypermax Performance series of coilovers too (just to be confusing) But i'm assuming these are more suited to track...

More details. With the stiffer lower springs i had traction problems in my car as it is pumping out in the vicinity of over 200kws at the wheels. My rears are Falken Azenis 255/45's and fronts are some Continental brand 225/40's (The tyre difference is playing havoc with my Hicas too) So i guess i am also wondering whether i should retain my current setup or try the HKS one, would this make a difference in terms of traction probs or would i have to sacrifice this in the pursuit of better handling?

Does anyone have the HKS setup or similar...just would like to know how the adjustable coilovers of this particular brand would do? Or are they too harsh for a street ride. I'd still like to retain some sort of comfortability and not feel every bump on the road but would like my handling to be A LOT better. Perhaps some comparisons would be good too...alongside Whiteline & other packages available, etc....

Anyway any help would be great - cheers.

Hi, the job of the spring is to hold the car up, absorb the compression loads and allow extension to make the tyre follow the road surface. Too high a spring rate lessons the tyre's contact with the road. It is not the job of the spring do other things, like limit the roll, that's the job of the anti roll bars. Likewise, it is not the job of the spring to limit the front end dive under brakes or the rear end squat under acceleration, that's a job for the anti dive and anti squat suspension geometry.

So I would strongly suggest a set of stabiliser bars, this will fix the roll. Adjustable ones if you want to tune the balance. If you seek an even higher level of handling themn I suggest the Whiteline Handling Package is for you.

Hope that helps

Hi all, i've been dabbling into getting an entirely new suspension setup and have my eyes on the HKS Hypermax 2 coilover kits...............

Hey, I posted something in the "General Auto" section (probably should've been here) but it is on my Hypermax Coil-overs...I had heaps of probs with this set-up, because I'm just a road user not a clubber. System is extremely high quality but really noisy!!! you'll see my post by me...'superspit' see if it helps!!

Mark.

Cool, thanks for the info SydneyKid, have been getting a lot of nudges towards the Whiteline kit actually..

Superspit - yeah thanks man, i was actually reading the other thread. Looks like the HKS setup might be a tad stiffer than I actually want. Our roads don't seem to be as good as Japan's super smooth highways!

    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
