Hey guys.

i have HSD HR coilovers for my R32 Gtr at present. now they are stiff as shit and ultra firm.

They have the adjustability etc, i dont know alot about these coilovers at all (i know they are budget brand but they came with the car, i would upgrade but for what i want they will do and the money is more useful for my tune/build).

Does anyone know what the standard GTR spring rates would be that these would come with??

My aim is pretty simple: i want to get some softer springs, i like firm but i also like streetable, the car was alright before on stock wheels but now its on 18s it has become alot more hows your father.

so want softer springs, also going to be installing a whiteline sway bar set to firm all the roll up.

Car sits practically low at the moment, i like it where it is, handles - pretty good, minimal body roll. I understand that adding the sway bars is gonna help that when the springs are softer.

Any advice, guidance anything would be most appreciated!!!

cheers

JD.

according to otomoto's website, its 9kg/7kg.

generally GTST/GTT run 8kg/6kg

mine handles very firm but once i raised it up. it was so much more bearable but then looks like shit with it being so high.

im not sure if a softer spring rate will do much in terms of reducing the stiffness but obviously you don't want to go too soft (4kg for example), go down 1kg or 2kg max.

is it stiff and bumpy all over or just the rears?

Thanks for the reply mate.

its stiff all over! its currently on the softest setting and still quite jolty.

Spoke with one of the guys from otomoto and they suggested looking at the height of the spring to check dampening etc.

Gonna go to the work shope count the coils and then let them know what i have so we can work out if they are harder springs or the stock ones with incorrect spring height possibly.

the car was being setup for targa tasmania when i bought it so they could well be really stiffere spring rates.

i mean i want a lowered car, but practical (which is where its at right now) i just dont want to feel every single bump crack in the road as much as what i am feeling, but i also want that firm feeling.

so will have a look see and see whats going on.

cheers

My Stagea is at 8 f 7 rear and a little too stiff for the street.

My GTR is 8.2 fr 6.4 rr and also a little too stiff for street. I reckon 8/6 for track, 6/4 for street is probably a sensible starting point.

Also interested to see what 6/4 is like

Ronin: - what car are you running the 6/4 in??

Spoke with Otomoto - Parramatta Sydney - the guy said that they should come factory for a R32 Gtr as 8/6, he said also that the settings for road should be anywhere from 1/3 closest to soft up to no more than 1/2 way adjusted to hard.

he said running them on totally soft (which i have had to do to tone it back abit untill i get it change in the next few weeks) wasnt good, he sugegsted to firsrly look at the compression settings i.e. lenght of the coil which should be 200mm. if this is any less the compression is too much and can give back feedback and feel.

So my car should be in workshop this weekend and im gonna look at what coils i have (i.e. count the number of coils and then tell Otomoto so they can tell me what settings im running) also gonna check out this spring length.

if its really too much etc and i need new springs, they are $100 an end, to me that is pretty cheap for springs to make em feel better and particularly as its a street driven gtr, will be 90% street 10% track. I have the facilities to change the springs quite quickly so not worried about swapping if have a track day etc.

stay tuned boys. Anyone have a R32 Gtr with these coilovers and has a decent street setup that i could tag along with for a quick ride/drive to compare???? will swing some homemade brew or petrol money.

i find it strange how it would be "not good" if running the dampers on totally soft.

they are there to be used on either soft/medium/hard??

good point in bringing up that the springs should be 200mm, im gonna check them out this weekend. my rears could do with a tone down as well.

It might be that they were adjusted incorrectly previously so using the wrong collar they changed the preload on the springs rather than adjust the height correctly. I would think thats why he is asking the spring length.

My house mate is running the HSD HR coilover in his R32 GTR, from memory we are using 8kg front / 7kg rear, the preload is just enough for the spring to be held tight and captive, damper settings are around 9 - 11 out of 16 front and rear, it's stiff but a very progressive ride.

Look, for an R32 R the unsprung weight over the fronts is about 400kg per tyre. So to trap/capture a spring (even an 8kg on) to the extent of having enough preload to affect it in bump means winding in up by 50mm from the point of starting to take up on the spring. Which isnt very likely.

It is more likely he is checking on the spring length to see if it is long enough in the first place and therefore not bottoming.

Anyway best answer is to buy some good springs/dampers & match them with some sway bars. Nismo use 5.5/4.5 kg/mm front and rear on their intro series and that is a pretty good set of numbers.

From Otomoto you can get 3.8/5/6/7 kg springs, maybe try putting your current 6's in the front and put some 5's in the rear. I don't think you will find this overly stiff with the dampers adjusted correctly. Just out of interest, what size tyre do you run?

I run 18x10 wheels with 265 30 tyres.

Got under there yesterday and had a quick look. front is 200m on the dot, rears is like 195mm, counted the coils so gonna call otomoto and see what springs i have in there.. once i know i will know a better way to go about setting it up.. might go down the next level from what it has in it wind up the compression to roughly a bit below half and add sway bars in. then should be pretty nice again.

ive got bc racing br series coilovers in mine.8s and 6s and i can can have it as soft as i want or as hard as i want 32 way dampers that actually work awesome coilovers for the money and ya can change spring rates if u wish do some research

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
