R33 Gtr V-spec Lowering Springs?

Hi.

I have a R33 GTR V-Spec, I like the current ride quality with factory struts and springs, I do not want it to get any firmer or harsher.

Is there any springs you can get that will retain the ride comfort of my V-Spec springs/dampers but lower it about 1 inch or so?

I'm really not into coil-overs are I have no need to adjust it and most coil-overs i've tried have been pretty harsh

Was thinking King springs but they appear to be a cheapo brand.
I'm unsure how springs specced for a standard R33 will work on a GTR, as from what I understand the GTR's suspension is quite firm from factory, the car handles just great.

Cheers.

Tell you a funny story.

My bc coilovers are much nicer to drive with than standard.

Wasn't the case for me.

Mine was ER series, 9/7, I absolutely hated it.

A few points come to mind.

1. Kings Springs are not a cheapo brand. I have used them on several cars and they generally don't sag or misbehave. There is only so much that a spring has to do. Compress and expand is about it! I have noticed that the exact same spring from Kings (to suit R32 GTR, which I have had on the front of my R32 for the last 15 years) have changed design subtly over that time. The new ones I put in last year (or maybe it was 2013!) were subtly different to the ones I put in last century. Same part number. So it goes to show they are still doing development work and tweaking the design.

2. If you want to be a brand snob you can certainly buy springs from other brands, like Tein or Eibach. Both are top notch options. But then, so are the Kings.

3. Whatever springs you choose, don't go much higher than about 6 kg/mm at the front. Kings R32 GTR fronts are about 5.4 or something. They are as stiff as anything I would want on the street. I have them in a RWD R32, so it's lighter and a heavier GTR could possibly use a little more rate, hence the ~6 limit I mention.

4. Standard dampers on Skylines are only so-so in terms of quality. Not bad, not great. Bilsteins are great. Buy some B6 or B8s to suit the car, add springs at the height you want, and you will be blown away with how good the ride feel is.

5. There are excellent coilover options available also. Look at MCA (there are recent threads here discussing them). Even if you don't want/need adjustability, what you do get is the ability to set the ride height EXACTLY where you want it and get the damping tweaked to dial out any little front-rear imbalances. Worth considering.

maybe the crappier BR range ride smoother.

I drove a Evo with BR series and I wasn't impressed also.

I prefer Tein or Bilstein or even KYB over BC.

You haven't tried Australian valved Super Streets before? It's pretty soft!

Been pondering about Street Advance, they're 5/5 or 5/4 from memory and they're $1000 from fulcrum Aus but you'll need standard strut tops.

A few things;

- BC make different coilovers with different spring rates

- Tein make different coilovers with different spring rates

- spring rate effects ride quality

- everyone has a different idea on what is too soft / just right / too hard

- the convention when you lower is to go for a higher spring rate, so you don't keep hitting the bump stops

- you may need to change a bunch of other equipment if you want to run lower AND be able to set the alignment correctly.

Obviously, there's variables between brands.

It's just that I don't have fantastic experience with BC coilovers as opposed to Bilstiens, Teins, even D2, HKS, Cusco.

Maybe the one I had is just shite? But it's enough to put me off from buying one or recommending someone.

Well said.

If you see things like 10/8kg (front/rear) then you're gonna have a bad ride.

Definitely not harder than 6kg front as stated earlier for a daily, will suit stock stuff well enough.

Yep, 6 at the front is the maximum for street car, light or heavy track work.

After driving @ Sandown in a WRX with KYBs, I won't want to drive it with stiffer suspension, semis or not.

And your back will thank you for that.

      RB25DE NEO with Haltech ECU

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      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.

      spot the stagea

      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.
