I've heard a rubbing when I steer sometimes - It was not until I was under the car this weekend that I figured out what the issue is .. My LHS front wheel is rubbing up against the stabilizer front bar, not hard on it but enough to rub against it.  Whereas my RHS does not rub against anything.  Any idea what may be causing this is there something to adjust?   The tyres are brand new 225/50R16. See the photos for a clearer explanation. You can see how close the tire is and the rubbing mark.

That's your caster rod/ radius rod.

Basically, the tyre is to wide for the offset of your wheels.  You may have previously had tyres the "same" size but in practice different tyre manufacturers have different actual tyre sizes for a nominated size like 225/50r16

Easiest solution, assuming you have plenty of thread on your wheel nuts, is to add a 5mm alloy spacer, which will push the wheel out 5mm, assuming they are legal where you are.

Spacers are not legal in Oz.

Wheels that fit correctly are the best solution - assuming that the wheels that you have are the wrong offset.

If the wheels are fine, you may find that you have something bent in the front end.

No, we cannot diagnose that sort of thing from photos.

What wheels are on the car. Width and offset.

Thanks guys but the new tyres are exactly the same size as the old tyres I just replaced - Is the 5mm space legal in NSW?  If I do not use the space or if I do for that matter will this impede my Blue Slip?

Are spacers the only fix?

Did you read Duncan's answer regarding differences in actual size versus nominal size among manufacturers? Are your new tyres the same brand and type (and sourced from the same factory/country) as your previous tyres? Do you have stock wheels and if not what is the width and offset of your current wheels? Another possibility is that you have whacked a kerb with that wheel and damaged the suspension.

Spacers are not the only fix. Other solutions are different wheels, tyres, or lock stops.

So being new to this scene - I have no idea what offsets are. I can tell you that the last set of tyres I had on the car were all of a different brand! Yes all my new tyres are same brand, same size, same batch, RS4'sall bought at the same time. The wheel sizing is 16 x 6 1/2 JJ 40 - It's my understanding these are genuine - are they? (See photo with old tyres) In hindsight when the tyres were fitted the wheels were balanced and one wheel was slightly buckled. (On their advice it's on on the rear).  So if it has had a hit - How can I identify what is outta whack and what needs to be replaced?20191102_085640.thumb.jpg.935b55e8c04ca57e5f9c773d4820b233.jpg

Those are standard wheels and you should not have rubbing problems with those tyres on that wheel.

Control arm bushes could be stuffed, upper arm bushes are probably completely rooted. Both of these could cause the upright to lean the wrong way. it could have taken a hit into a kerb and moved the subframe under the chassis rails. You'd be best off taking it to a (good) wheel aligner to see if they can work it out.

225/50 too fat for 6.5 (it's for standard GT-R 16x8 wheels IIRC), should be 205/55. But shouldn't have rubbing issues.

Standard R32 GTS-t wheels are +40, perhaps tyres are deflecting too much? Looks like your car is lowered so geometry would be off.

Most likely something is bent.

      Duncan's V37.......race car?

      By Duncan · Posted

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.
