Hi Guys,

I have a question regarding rim / tyre size and why this is subbing only on one side of my car?

I have an R34 GTT on stock suspension and recently got some new rims and tyres fitted.

I’ll try provide the info as clear as I can in a list below:

· R34GTT Stock Suspension

· 18 x 9 rims

· I am unsure of offset at this stage (will confirm with the shop). I believe it’s different for the

front and rear. This is the info I have on the invoice: 18 x 9 ET22 and 18 x 9 ET15.

· The tires are 225/40 R18.

The Issue I have is only with the front left wheel:

· Moving straight / reversing straight = no issue

· Forward while turning right = no issue

· Forward while turning left =mild rubbing depending on speed and it’s near to full steering wheel lock. (I can go over road bumps and pot holes in a straight line with no rubbing).

· Reversing while turning left = massive rubbing / scubbing noise, sounds like the tire is hitting something plastic to me. It will continue to make this noise while reversing until I straighten the car out. This is particularly embarrassing when reversing out of car parking spaces and having this god awful scubbing noise the whole time.

· Reversing while turning right = no issue.

So this problem seems to arise when I’m turning the steering wheel to the left and it is only evident on my front left wheel.

Is this suspension related?

Is there something in the front left wheel arch that could cause this problem, as it’s not happening on the right side.

This was happening with my previous sets of rims also but they were 20” (Horrible things) – I thought they might have been the cause but since moving down in rim size, I am still experiencing this issue. :unsure:

Any advice would be much appreciated.

Cheers!

Dex

Your offsets are 22 and 15.

You need to get down on your knees and look to see where it is rubbing. It will either be rubbing on;

  • the outside edge of the tyre against the rear side of the wheel arch,
  • the inside edge of the tyre against the engine bay rear part of the wheel arch (less likely),
  • the inside edge of the tyre against the front side of the wheel arch.

It may be doing more than one of these seeing as it does it differently between going forward and backward. Going forward I would bet on the first of the above points. Going backward I would bet on the last of the abpve points. But I wouldn't bet a lot, because there are always other options!

If I were to point my finger at anything in particular, I would suggest that the caster rod bushes are probably rooted and allowing the wheel to move fore-aft in the wheel well as you apply loads (ie, drive forwards or backwards). But other buggered bushes can cause similar problems. The plastic liner could also just be loose in the wheel arch, sitting too close to the tyre.

    • Add to this... What blew the fuse too? If a circuit feeding power to the coils was blown, how were the coils even functioning to let the car start?   There is some seriously wrong wiring in that car for certain, and I'm betting there is some melted cables somewhere, but I can't explain the 30v either, unless there is something back feeding on that power line that has a dodgy power system and the electronics are giving it hell.
    • This is typically the case with such threads. What I cannot quite get my head around is where a reading above 12V (or 13.8 or 14.x or whatever the maximum achievable voltage might actually be in that specific car) comes from. 25V or 30V should be completely impossible. There's no way to create it. Hard to answer that question. It will literally depend on whether the current tune relies on the values as set. I'd guess it probably does. ie, the real base pressure being 49 means that the flowrate through the injectors will be higher than if it was 43.5. The Haltech's modelling should be handling that, but because it thinks the pressure is only 43.5, then..... I dunno. It should be thinking that it will be injecting less fuel with each pulse duration than is actually happening. So, something is definitely not-as-it-should-be, but specifically what that is is beyond my abilities to imagine. Someone like Dose who spends more time with Haltechs might have a better thought.
    • Bit of a late reply here as me and my wife have been really busy with new born twins. I finally got these issues fixed and it was something really stupid that caused all of this 🤦‍♂️... After alot of mucking around with trying to figure out what is causing these issues, I back probed one of the R35 coils on the power 12v supply, with the engine running it got 25v! And I thought, hang on..., this isn't normal. Measured my battery with the engine running to check for over charge from the alternator and it wasn't that. So then I dissconnected the R35 PRP coil harness and backprobed the power supply on the engine loom where the ignition coil harness connects, with the key on ignition (engine off) it measured 30v! So then I had to trace where that high voltage was coming from and it lead me to the brown relay "ECM & IGN coil relay" inside the cabin next to the ECU on the passanger wall. This relay feeds power to the ECM and ignition coils. Tried swapping it with another same relay. nah still 30v.. coming from the 2 green/white wires in the brown relay. So then I set my multi meter to the beep continuity mode and probed every fuse on the fuse box inside the cabin to try and find this high voltage power source. Wasn't any of the fuses inside the cabin. Then probed all the fuses in the engine bay and BAM, got my power source that was a 10AMP fuse called "ENG CONT". Pulled the fuse out, and what do you know... it was blown. 🤦‍♂️  So then I quickly replaced it with a new 10AMP fuse, started the car and yeah haha [insert extreme face palm]... The RPM blimping thing went away, car idles smoothly now like what it was before. I swear! I checked all my fuses with my test light twice before I created this forum thread. I think, maybe because one side of that faulty 10A fuse lit up on my test light, I must have thought it was still ok and not blown. But now I know to have both sides light up on the test light when checking fuses... I hate diagnosing electricals.... I'd take mechanical problems over electrical problems any day🤣. Drove the car around my suburb with the engine up to operating temp and it runs fine like before. However, I notice that my fuel pressure is still at 49psi. So I'm thinking this must be normal for my system as I've upgraded the stock fuel pump to a Walbro 255L/h with a constant 12v mod.  But anyway, I'm just glad to have my daily back on the road! Thanks everyone for the replies on this thread, all sorted now! One thing I want to ask you tuner guys, my base fuel pressure on the haltech main settings are set to 43.5psi from default (my tuner must have not checked the fuel pressure maybe when tuning my car?). Do I set it to what it actually is idling on at 49psi? Or just leave it ("if it aint broke, don't fix it/leave it")?  
    • The max they would go for me is 50.
    • That cannot have been a fun set of drilling. The stock "baffle" looks identical to rb26, I just cut fuel cell foam to fit the full length under the baffle.
