okay, so now after installing 17" rims, i was having the problem with tyre scrub
i knew the shocks were screwed, so they were replaced with nice shiny, and much more stiffer new shocks.

on the drive home i had no problems... until, i had a balance shift corner where i turned left, then quickly turned right, and the sudden lift and drop from the suspension gave me the infamous guard rub sound yet again... grr

after also trying abit of a bad dip and speed bumps i am still getting bottom out and outer guard scrub.
the rims are 6.5" wide, so lock to lock is no problem, but its when the suspension compresses while the tyre is turned, or when a full on hit to both fronts is apparent.

the springs were tested and rated as 'okay', which could mean anything from deemed fit for rego, to deemed fit for stock size rims, but meanwhile, im still getting rub and having to take corners carefully.

so, for those with 17s on, can u give me some insight as to what you did, ie: changed springs, change shocks, rolled guards?

i know some of you guys have done it, and doesnt seem youve posted a problem, could just be my old springs, but as said they were 'okay'

sorry for long post.

how wide are your tires and whats the offset of your mags?? and is it scrubbing on the rear or front??

im still yet to scrub anything ;) and ive taken corners with some force

yeah, the fronts only, the rears are fine,

tyre size is 215/45.

rather large i thought, but thats what they gave me....

might be tyre size also, yeah.


offset, dunno, would have to research that

yeh tyre size is right and should be fine, any idea if its scrubbing from the outer or inner of the tyre, a bad offset can do this tho. could just possibly be that your springs are too soft and your getting to much movement up front

my thoughts exactly, i'll try to find the offset, didn't bother me as the wheels guy actually called me back when i asked tho, and tho not giving me insight, informed me there would be no problem....

but hmm..... there is.

its hard to say how its scrubing, but i suspect its the outside top lip thats rubbing, primary reason i say that, is the front tyres are directly inline with the guard, they dont sit inside the guard, there flush, you look direct on from the front or back and the front wheels are sitting out from the guard...

hang on, see if i can find that pic i have., will edit post.

edit: duh, all my pics have the wheels turned.. clever.

the back wheels for example, i can only just get my hand up inbetween the tyre and the guard....

Well if the guards are sitting flush it should be that when the front dips the guard hits the tyre and you get scrubbing, sounds like the offset might be wrong...

yeah, annoyingly can't find anything anywhere on the offset of my rims, have sent an email to the tyre guys, doubt theyd get back to me anytime soon.

hmm, what to do, easy fix is to create negative camber, as i think there is abit of positive on both my fronts. would help maybe a bit.

but mm.... bit of a beeline

okay, finally got some word back from the tyre guys
they have either a +25 or +40 offset

no insight as to what mine are tho, they do to many cars...

which one should I have?

mine havnt had any probs really, i did roll the guards myself when i thought it was happening though. Just use a mallet and take your time, the paint is a bit old so it can chip so be careful.

by chance do you know your offset tele?

Offset should be stamped on the inside of the wheel (rim or spoke). If the offset is 40 then
it is ok. If 20 then its illegal. Offset changing changes track. Track cannot be changed by
more than 25mm which means offset cannot be changed by 12.5mm. Since OEM offset is
46, 20 offset means offset changed by 26mm which means track has changed by 52mm.

Since decreasin offset increases radius of turn because wheel/tyres sticks out further,
rubbing generally occurs due to the outer edge of the tyres rubbing the splash guard front
and back. See attached image. Unless the wheel/tyre is sticking out very far (20 offset)
and the car is lowered a lot, tyres shouldn't be rubbing the wheel arch. See attached pic,
as the tyre curves upwards when suspension is compressed.

hey, sorry not sure off the top of my head, went and found the receipt dating some years back for the wheels and it didnt have the offset on the receipt soz.

hey man, nice an informant, will look at a rim when I get home later.
on a side note, yeah it should be rubbing on the inner spalsh guard, but in actuality it is rubbing on the flanged metal guard.
as to why, I have a few sneaking suspisions
1. is that I do not have any negative camber to compensate the suspension crunch as to not rub the guard
2. the coils are simply to worn, despite being tested as 'ok' for the larger rims.
3. I damaged my right front shock on a massive dip couplea weeks back, infact the day after I recieved the shocks, *tho in testing it myself with bounce, they are rather stiff*

I'm looking to strap a camera with recorder and link it to my tft in the car to get an insight as to what is making it happen, I assume this should tell me, when and why it is happening, and how to fix it.
alternatively, new springs and maybe a camber correction kit is in order.
