Gtr Handling Like Crap Since New Bigger Rims And Fatter Tyres

[MrStabby]

I checked your printout - sorry i cant add anything more with my limited knowledge. AFAICT its looks reasonable. Ask in the Vic forum what suspension place is recommended in your area. I've never got the service I was looking for in a chain like Pedders or Bob Jane.

Tyrepower ringwood seems to be the place to go, long history of perfect aligning. Makes sense, lower overheads from a smaller shop and less professionalism (cough bobjane massive wastes of space).

Will be dropping it off tomorrow so will see what they find.

I use them too.

+1mm per wheel station seems about right.

Would you be interested in having a drive to see what you thought, and potentially mine in yours? Cos the mechanics are definitely scratching their heads a bit

I just read that you have only 32 psi in 30 profile KU36s. Pump them up to 38 and try that. They don't work below 36 in my opinion. I run my 235/45-17 KU36s at 36 - 38. When they have fallen to 34 I start to wonder why the car isn't going where I want it to.

36 - 38 psi won't wear out the middle of the tyre either. I never have, over several sets of KU36.

Too much toe in not enough castor.

You want more like 6deg castor

Toe in zero front and rear

I am running 3 deg neg camber front and rear for the track but it turns in great on the street as well and no undue wear so far(4000km). Try at lest 1 -2 deg neg or whatever you can get with your setup

Tyre pressure is? - 32psi

GTR-34A - Like i said they're brand new tyres Kuhmo KU36 18/30/265 all round,....

Is the tyre still rubbing on full right lock?

When tyres are cold, is there any improvement by pumping up tyres to 38-39 instead of 32?

Your profile is only 30 remember.

I was running 285s on a 10.5 rim with AD08s, never had any issues at all with tram lining in the dry. The car would jump around a little if there was a major deviation in the road, but any car will do that.

Wasn't running too much camber and just a good alignment from Racepace (their own mechanics do it), same alignment i had when i took it to the track, so it was all purpose and worked. I ran 32psi in them for street duties.

I did have alignments done by a few other places, everytime they just couldn't get it right and it would drive like rubbish. Perhaps give a GTR expert a go, rather than places that work on all cars?

That said in the wet it would tram line a little bit with such wide tyres, as the AD08s are especially wide due to a nice sidewall, however it really wasn't a major problem at all, even when i had 265 semi's on the car (was a little more squirmish in the wet, slight movement in the dry, overall still easy driven)

this tyrepower ringwood, is it tyrepower croydon? because there doesnt seem to be any tyrepower ringwood.

[Thelen]

Tyreplus sorry, on bond st just down from barry bangay. or maybe he did mean tyrepower in croydon, but he said it was close. i'll ask again

Ash thanks for the suggestion although this place (barry) the head guy knows GTRs, and he said the printouts for the align match what he knows. I might ask for the specifics to post on here to compare, although obviously a 32 is different to a 33, plus all the other stuff you've done to your car

Would the fact my tyres are a starting to get low make a difference?

Thanks for all the responses guys - i'm going to get a third opinion by a one of the specialists recommended.

I'm tossing up between tyrepower ringwood or racepace

I'll post back results here once done.

[R33-RB26DETT]

Advantage suspension in Moorabin fixed it.

Was due to the wheel alignment and also a worn bush in my rack.

[wolverine]

What were the final settings?

[R33-RB26DETT]

Toes was out by 2.5, he brought it in by 1.5 apparently
