genuine nissan HICAS tie rods (different to front tie rods!) are about 250$ for both. from nissan. not cheap. but if you go ling long...well...yeah

well if you got a GT-R I wouldn't use ling long, but I own a R33 GTS-t (ling long is acceptable) haha :)

^ maybe he likes HICAS :)

Theoretically it makes sense to have HICAS, and the system was revised in Series III GT-Rs like yours Paul, prior to that HICAS was pretty shit.

I've tossed mine in the bin too, but I own a fridge.

A lock bar doesn't really solve the problem that you probably have anyway. The outer tie rod ends are the spot that wears the most, and a HICAS delete bar leaves those in place. You'd still need to replace them.

Question.....does 5500 rpm relate to a particular road speed at all? HICAS is known to exhibit it's problems at particular speeds because the HICAS computer reaches "panic mode" at those points when given sensors are not working. Steering angle sensor is one that people often accidentally lose when they put a different steering wheel on the car and the hub doesn't have the drive pin for the steering sensor. On my car (last century) it would crank the steering wheel over to the (left? right?) by about 45° when over 80km/h just because no steering sensor. HICAS panic. No steering sensor also meant I couldn't put it into diagnostic mode which made it very hard to work out what was going wrong. The HICAS computer also looks at VSS, and for all I know in the later GTRs it might even be looking at the G sensors. There's lots of things that can make it act flaky.

Try to put it into diagnostics mode (no, I don't know how to do it on your car, only on an R32). Failing that, get a mechanic with a decent scan tool to hook up to the Consult port and see if there are any codes in the HICAS computer. You may have to take it for a drive and trigger the fault to see anything.

yeah I'm thinking the same

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
