hi guys, just wondering what size wheels and tyres most of you guys are running coz my 32 gtst only has 215-45-17 size tyres and they are scraping on the gaurds when i go over a decent sized bump at 80ks or more...(and when im turning at high speeds or braking hard). Have you guys had to roll your gaurds to stop this or is my car just bein a woman?

Any insight would be much appreciated. Thanks guys.

Leigh

Not very helpful Paul, i think he is aware this is a V35 forum, maybe he just wanted to get an idea of what tyres we roll with our V's.

With that, i will have to check mine for you later on if you wanted to get an exact size.

it will probably be different story with the R32 because we V owners seem to run with with bigger size than the 32s. so i suggest ask the fellow SAUers on your state aswell.

Sorry Sir-black32 :D

Sorry about this but I am not sure that Paul was being rude, but he does have a point and without trying to be 'unhelpful' it would be better if Sir-black32 asked this question where people with R32's frequent.

Specifically but rheotorically, how does a V35, equate to an R32 with our without rolled guards?

Rolling a V35 guard for a Tyre to Guard mount problem will not be the same as rolling the guard for a R32, even 'if' it had the same size wheel and tyre on it.

To mention my R33 Gts-t... someone had fitted GTR front Shocks to it when I bought it so it used to run out of travel on high speed corners with bumps, never hit the guard though only the inner plastic guard. If you didn't know the GTR front shock is about 40mm shorter than the RWD only GTS-T.

Some things to consider if I am trying to be helpful.

Do you have the correct size tyre for the rim?

Do you have the correct size wheel/tyre assembly for the car?

Is your ride height appropriate, ie more than 100mm minimum?

Are you front springs too soft?

Are you front shocks too short - see above?

Are you front shocks out of oil?

Are your front shocks leaking?

Sorry guys, didn't realise id posted in the v series area.... Had a few windows open at the time. obvisouly posted in the wrong place.

But while im here i might as well fill in a few details.

According to the plaqard the car came stock with 205/55/16, so upgrading to 215/45/17 is legal and "shouldn't" have any clearance issues.

The car is at standard ride hight.

My front springs aren't soft, nor do they appear to be leaking or out of oil.

Thanks for the suggestions tho guys.

Big problem here, you need to go back to the shop and throw the new set-up at them.

You tyre and wheel combo is now bigger diameter (9mm) and your speedo and gearing will have changed... the difference is not a lot but it may be why your tyres are scraping the guards.

Profile =

Old tyre 205/55/16 - 55% of 205mm wide = 112.75mm

New tyre 215/45/17 - 45% of 215mm wide = 96.75mm

Plus Wheel diameter

Old 16" = 406.4mm

New 17" = 431.8mm

= a total diameter of

Old 519.15mm

New 528.55

Regardless of the tread on the specific tyre you now have a larger set-up.

If you check different tyres (Brand and Type) in the same size the rolling diameter will nearly always be different, so if you have a 'larger' tyre this will add to your problems.

The new tyre is not the right size.

However at standard height, I doubt this should be a concern. Something still may be amiss.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!

      I need more than help to finish my R33

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.
