I just installed on my ride and playing with the setting. The R-Tunes has 4 setting (front) and 8 settings (rear) with a height adjustment of +-20mm.

My problem is that i find the rear is quite firm (set at 4) but gets bouncy when on freeway. If i set it less than 4 the bouncy effect will get worse (sometimes u get double or triple bounce) plus the bouncing effect is fast & short which really shake my kidney to bits. The front was set at no.1 but now i like it when it's no.2 setting where the turn in is very sharp and ride compliance has a nice firmness to it.

My question is how can i get the non of the bouncy effect of the front & match it for the rear?

Does the ride height has anything to do with the compliance of the bouncy effect. Since this is a full coilover suspension, should i increase the height of the rear (so the spring will be more firm) then set it slightly softer setting like 2 or 3? I was advice to increase the setting to 5 or 6 which help reduce the bouncy effect but the ride now is quite hard for everyday driving.

Appreciate anyones help who know coilover for the R-Tunes. :(

Bounciness if probably the high spring rates on the R-tune setup.

Im pretty sure the R-Tune spring rates are quite stiff.

It may be worth taking the car to a reputable suspension workshop and having the setup 'tuned'

Yes the spring rates is 9kg (F) and 8kg ® which is quite hard so the adjusting height/firmness is the only way for me now.

I try using the same ride height and adjust the tire presure higher 36PSI all round and lower the setting to 1 for front and 3 for Rear. Less bounce and the car handling felt better. Btw im using Toyo T1R tires which has soft sidewalls, so pumping up the pressure make the turn in sharper.

One last question, would the ride height of the coilover when i raise it will stiffen it up (coil spring get more compress)?

Appreciate everyone's feedback.

I believe SK's optimum recomendations are 355mm front and 345 rears measured from center of wheel to guard.

I've got tein super streets and have them at 350mm front and 340 rears...

Looks wise, the fronts could still do with a tad more lower, but any lower would mean more camber wear on the tires without bolting on a camber kit front n rear.

Thanks Nismo for the feedback.

My current chamber for front is 1.6 FL & 1.9 FR and Rear for both is 2.5. Just wondering why is the rear set lower? Would the handling be neutral, understeer or oversteer? Presume my tire pressure is set at 36 PSI all round. The current setting for the shock front is 3 (4 is max) and rear is 6 (Max is 8). Im trying to set the car to neutral. Appreciate your great assistance & advice.

Just checked my ride height for the R-Tune Nismo.

Front is 358mm & Rear is 343mm.

Do you thing this would make much difference in just a few mm from SK setting? That's why i could slightly see the rear to be much lower than the front. Need advice. Thx in advance.

The rear is set lower because the rear guards are lower than the front. We measure from center of wheel to guard yeah? So with those recommended settings the car is pretty much level. I have seen a lot of ppl go the same height all round as well...not much harm I guess. I'm looking at lowering my fronts maybe another 10mm coz it still looks high from the front.

I notice that the front is high too (vizually) but the front coilover doesn't have any pillow springs. Do you think the ride will be more harder/softer or there is no effect at all other than for looks? I understand that the chamber will change to be more negative though. So far seeing all the japanese magazine & all Hyperev GTT magazine, they all seem to set the front quite low almost a 1 or 2 finger gap. Anything to do with our FR effect to compare to a GTR (AWD)?

I'm just about to pull a set of these out from my car. I found that they were quite good and not bouncy at at, stiff if anything. Question - do you know what end of the scale is stiffer? The low end of the scale 1, or the high end 8?

Are you sure they are R-Tune? R-Tune have the remote canisters and have seperate bump and rebound adjustment. 20 levels of bump adjustment and 30 of rebound giving a total of 600 settings per shock?

they look like these (see the gold knobs at the top, and black ones at the bottom):

I think you'll find they are R34 GTR R-tunes, not GT-T :)

actually they are 32 GTR R-Tunes. :) (mine).

I didn't know the ones for GTT used different dampers. I just assumed they used the different length, and different attachment style. but I guess they use the different dampers too. my bad. so they just have 1 type of adjustment?

Mine had the helper springs. Iam trying to get the balance feel for the rear which is either too bouncy (soft) or firm. The front feels compose & compliant on most surface when set no.2 setting. I'm curious, let just say front has 4 setting & rear 8 setting, if i set front no.2 does the rear has to be no.4 to balance it up?

Good question, I'm not too sure either. Are your springs black or silver? One of the vic guys also has these and his are black, mine are silver. I think there must be different spring rates? Mine also have the helper springs.

Mine is Silver. Ilike it when the rear is at no.6 when i plan to drive in twisty journeys. But when come to city driving, it's a little too firm & with very short travel suspension. DO you guys reckon if i raise the rear like 10mm more will make any difference on the compliant rate?

beer bottom, have you set yours up and what spring rates etc are you running...

they're the same as these I expect...

:happy:

    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
