Hi Guys, Just sorting out some bilstein shocks, and I'm looking at springs.

Question 1, will GTR springs fit GTST shocks? I dont think so, but not sure??

And any suggestions where to get springs, Looking for 7-5kg range to suit gtst shocks. found some 6kg apexi springs but they suit GTR.

also I am after linear springs.

any help would be appreciated.

Going through a similar thing myself. Chasing springs to go with my bilstein shocks for R32 GTR. Whiteline don't do them anymore, Tein S-Techs hard to get, Lovells and Eibach don't appear to do them.

Probably going to go with King Springs. Just e-mail them via their website contact details. Will get back to you within a day (Easter holidays, will probably mean Wednesday)

Why do you mean by Eibach dont do them? I have the red Eibach springs on my Bilstein shocks on my R32 GTR. For what it is worth they replaced Whiteline springs which now sit gathering cobwebs in a box next to some black Eibach springs that bolt straight up to the Bilstein shocks.

If you want to use springs from red (motorsport) Eibach range you need the threaded section that fits over the shock, the two bottom collars, the top spring seat & the spring. Eibach do a massive range of springs. You need to specify the spring length (eg for the rear in inches so a 8" long spring reads a 0800 on it), ID for me its 2.5" (which reads as 250 on the spring) and finally the rate in lbs/in. Divide the number by 54 to get kg/mm, so a 275 lb spring equals 5.1kg/mm.

I'm looking at that ground control kit too, but a little unsure of the ideal spring length for the recommended 355/345 ride height. Whats the popular option? 8" with helpers? 12"? think the stock spring length is like 355mm (14")?

im refering to rears btw

Slightly off topic but does anyone know what the standard Whiteline Spring Rates are for 32 GTR?

Im running a set of Whiteline springs with my Koni Yellows (Damper and Circlip height adjustable) and im convinced the springs are way too soft...ive got the fronts set at the highest setting yet they will still bottom out over a harsh enough bump and the rears are much the same, the shock is bottoming out...

Waxhead, i'll sell you the Whitelines out of mine :)

it shouldn't

either the valving of the konis do not suit the springs or the shocks are worn

factory springs don't bottom out the standard shocks, and whiteline springs arent that much lower

Yeah, I know mate, its strange, they arent that low at all but even when the car is stationary, I can see the shock piston is a long way through its stroke...and theyre definitely not worn, I have damper wound right up and they're firm as, it rides sweet over nice flowing bumps.

Do you know what spring rates Whiteline are?

whiteline spring rates are about 3.xkgs front and rear, its just a tad firmer, like 20% over stock i think

i had them in my old skyline with bilsteins and i thought it was a pretty good combo, new car has kings and bilstein, the kings were a lot lower and hits the bump stop more frequently. changed it to tein medium which is about 4.xkg front and rear and it was a lot better

i can definitely feel that the tein mediums are harder than the whitelines again, being 4.xkgs, the bilsteins seems to like them more, it handled rough road surfaces a lot better than the softer springs.

for softer springs, you will need to adjust the shocks to a firmer compression, softer rebound; and opposite for hard springs

i also had konis in a toyota i had before and it just bottoms out so easily as well, the konis were quite new, so i just thought that the shocks were not suited to the springs

Ahh....excellent stuff chiksluvit. I have thought about getting slightly firmer springs for my bilsteins as the king springs seem too soft for me (the the shocks seem valved for firmer springs anyway in my mind). So the tein mediums are both firmer AND at least as comfortable. ?

yup it is

you can definitely tell that they're harder than the kings, from more feedback from road surface, yet its not uncomfortable because when you go through really rough roads it doesn't vibrate as much, like its better controlled- not sure if it makes sense

an example is say lady game drive, section closer to chatswood, with the kings I will drive through and it'll feel crushy and even get rattles from the dash; with the teins i can still feel how bad the road is, but i won't get rattles from dash, like I only feel what the road is like but not any extra vibrations- upside is i think a better controlled spring oscillation means better road contact, or road holding capability.

conclusion is bilstein valving definitely suits harder springs more than soft springs, bilsteins on my car are only about 1 year old so far.

without telling my mate that i've changed springs, my mate commented on the change in ride quality when he was sitting at the back seat.

bear in mind my car has 27mm sway bar front and 24 rear with poly bushes on the front upper inner and caster rod, so the road surface feedback is really direct

the bump stop does visit the shock body more frequently on the kings than the teins, doesnt happen often with the kings but has happened for eg. when i hit the shallow potholes at comenarra parkway. or the far left lane on pacific hwy in chatswood going towards the city direction just before mobil service stn.

in fact they haven't had a chance to meet yet since i've got the tein mediums- i'd say its because the kings are lower and softer

they are progressive springs, but the soft section is fully closed up with the car on the ground, which makes it a single rate spring- pic attached

just so people know, I contacted KING's about making me custom items, and they said its no problems. I asked about some 7kg front and 5kg's rears in standard spring design to suit bilstein shocks with circlip height adjustment and I think it was $300 per pair, and 12-15 days as they are made to order. This is the way I'm going to go.

cheers

I would definitely say that this is also the case with the Koni Yellows I got from Importmonster, from what ive read the valving on the Koni yellow is very hard...time for some new springs or coilovers...

7kg/mm front is pretty damn hard, but I trust you know that.

yeah, not as brutal as the 10kg's with shit valving that is in there atm lol.

I'm going by what other guys who race at local tracks (symmons plains & baskerville) here are running, it will either be 7's or 6' up front with 5 or 4.5 in the rear.

I asked King Springs for 4.5kg front and 4kg rear (at catalogue lowered height) and they said they could do it BUT they won't be captive at full droop.

Mr Untouchable are your springs captive at full droop, or did you have to alter something else?

ahh forgot about this thread i'm a slack ass.

I ended up using HSD sleeve kits, so I have full height adjustment and also can run any 65MM ID spring. opens up a whole world of options and i will be running helper/retainer springs also.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
