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.

      R32 GTST - 600KW+ RB28/CD009 Build

      I've done a few BMS systems. Code in Canada use to force us to have any safety components outside of the PLC but with a code change back in 2018 I believe it was, we can now use safety PLC's to control everything. Sadly to your point, AB Guardlogix safety instructions for example are only available in ladder.  Machine safety is a very big thing here though, you're constantly forced to migrate to the next best thing by OSHA. I honestly prefer safety plc's, including anything from AB more then I do working with old school safety monitoring relays. PLC is only one portion of it, the rest of the electrical still has to follow to meet SIL (Mechanically linked dual contacts, bla bla)  Now tell me how to feel about safety over comm's (e.g Ethernet/IP CIP) on a unmaintained network haha

      To your point, boolean logic. We're not only working with bools in ecu's, so it's very limiting. I wanted to setup a low WMI pressure alarm. After 1 second I want WMI line to hit 100PSI, 2 seconds 175PSI, etc. and trigger an alarm if it doesn't meet those thresholds. This would of taken me one very short line of text, but instead I had to bugger around with generic timers, conditions, etc. and so forth.

      Low oil pressure after WOT

      By pogman · Posted

      I much prefer that to an actual oil pressure issue, never would of thought it would of been a volt drop issue but SAU brains win again. Guess ill be turning down the oil pressure limit for the track and hunting some grounds. Ill hopefully update this thread with some high oil pressure and solid ecu voltage logs.

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!
