Hey guys, I dont know if you would call this a thread bump. My currently upgraded 290rwkw [R34GTT] is too much power for my very stiff Cusco coilovers (not sure which model, doesn't have adjustable damping) in that there is not enough grip and it starts spinning and skating on boost and makes me look like an ass. I hate these coilovers, theres very little flex when pushing the car down from the back and front.

I am wanting to spend as little coin and soften up my rears, are a pair of BC BR rear coilovers the way to go? Or just get softer matched King springs or something? Front is ok, not looking to change that. cheers Ron

Find out what spring rates are in your coilovers before doing anything else. You need to know where you are before deciding where to go. Read the thread on how to work out your spring rates, and/or remove the springs and test them yourself.

L I K E ! ! Thanks GTSBoy..

Remember Ron, i have more wasps and i can get mine to grip up sometimes.... You shouldnt have any drama's once you set it up right :)

Thats right, but these Cuscos are HARD, not good man, especially since theres no damper settings, well the clutch is in so one more thing off my mind...

Just installed these on my R34 GTT. Standard spring rates (8/6). VERY comfortable and streetable on soft damper settings. Also drove them on hard all round and was very stiff, good for track. Will probably get a bit softer once they wear in.

^^^ +1 mine are in transit, BC the CHEAP way to go

FYP :)

They are a good cheapie solution but they are in no way magic, a quality set of coilovers will do so much more than the BC will..... I run them with no complaints, but if the car becomes more track oriented then they would be one of the first changes.... They are comfy though!

hahaha yea its a small fix i guess.....i used to have some Tein's on my 33 but that was way too stiff.....

These are basically like the oem, just a little firmer with adjustable height.

I still have stock one's on the 34 so this is a nice replacement :)

All done! Set it on 6 soft setting. Seems pretty good till now for road use.

120mm at the back and 100mm at the front.

Did you set them soft 6 front n rear? I've just installed mine and it feels a bit bouncy... Any reasons to why ?

Cheers

I've read this a few times but every time I've read this noone has really linked or suggested anything that's obviously superior, and why..

As a newbie with little-to-no info re: suspension and relying on the SAU Search tool -> What would you suggest?

I have a 34, but its a GT chassis (with a non GT engine..), which I have read uses R33 style suspension.

Yet BC BR's have different part numbers for R33 GTST and R34 GT suspension.

I presume there are differences there so R33 is not exactly the same as a R34 GT.. so searching for R33 GTST gear may not even be compatible after all.

Theres a lot to be said for "it really is 100% compatible, cheap, and does the job", what else is out there thats the next tier up?

Pretty much BC BR and anything around that price mark (1100 - 1500) will be the same (and by same i mean same factory different paint). The next step up is, as GTSBoy said, more money - but it doesn't have to be thousands per corner, you could choose the tiny step of: 1600-2500$ for Cusco, Tein, Greddy, JIC, and if you find a good deal/stretch your budget, 3k$ will get you Ohlins. Though some people would argue that Cusco Tein etc are not worth the price...and I have to say I'm only speaking out of research I've done while deciding what to do, and speaking with people who have these coilovers.

You could also consider not using coilovers and going with a spring and damper setup instead. I myself have gone down this path with Bilsteins + King springs, I'm about to get them installed this week - I will rarely, if ever, use my car on the track/drift so coilovers and constant adjustability is not an issue. Set them up once and set them up correctly, leave it.

Oh and - I've talked to a few mechanics and they ALL recommend highly HSD.

  • 4 weeks later...

IMO: 8/6 is track, 6/4 is street. I live with 8/6 but on bad roads its a bit shit.

WRT the amount of adjustments whether 30 or 33 makes no difference. Some of these cheapo coilovers the adjusters do bugger all anyways according to the shock dyno, in that many of the adjustment positions are the same level of dampening. Ie, its ricey.

+1 to BC's with rubber mount top.

I just talked to BC technical support.

They recommended 6/5 for 'fast street' and 8/6 for track use.

They also said only the rubber tops (RA) make sense on double wishbone.

    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
