just a quick question to do with the 4WD system in gtrs.

i want to know if i fit lower profile tires on the rear of the car, will it start throwing power to the front wheels when it doesnt need to ?

i know that with mercs if u fit diffrent size tires on the back, the cars *ESP* system pics up the wheels are not spinning at the same time so it use's its *ESP* to try and fix it.

i have 265-35-18 on the front and want to put my 285-30-18s on the rear of the GTR.

i know its prolly a STUPID question but just not too sure if it would b ok or not.

I think you might have a problem with those sizes. The key is to have the same overall diameter with all 4 wheels. With your 265/35's on the front your profile is 92.75mm and with the backs it is 85.5mm.

Just as an example I had 255/40/17 Federals on the back of my 32 with approx 75% tread and then replaced the fronts with some brand new 255/40/17's and I had a constant 10 on my Torque split gauge. Unfortunately had to drive to Stanthorpe and back like that. When I got back, switch the new tyres to the back and presto - back to zero.

Hope that helps

Dirk

as everyone has allready said, wouldn't be good, the car would work but it can cause a lot of problems with the attessa as well as i'd imagine wearing out transfer case a lot quicker.

I have been told though if you pull the attessa fuse you can run diff size tyres as long as you want in rwd mode.

why did you want to run wider tyres at the rear in a 4wd car:confused: Does your car see the drag strip regularly?

Hey Melv, is 265 all round not enough?

doesnt seem to be working to crash hot, it just sliding all over the shop in 1st gear.

i have crappy nankan 265s on all 4 atm but they just arnt sticky.

bought two brigston so-2's 285s cheap thought it might help stablise the rear end a little.

might have to find some 265-30-18s for the front now.

      ER34 AT ECU and HKS SLD pins

      By GoHashiriya · Posted

      Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      Rear suspension upgrades

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
