Polo GTI, Rear Toe Out Shim Ajusters.

Posted this earlier in another section with no replay, so me try again here.

Or if anyone has a different idea to solve the rear 3mm. toe in that the Pog has. This rear toe in doesn't effect road driving too much, but on the track it chops the rear tyres like you wouldn't believe.

So they're a plate that's that varies in thickness... I wonder if someone could machine some up for you? I think there may be a couple of fitters hanging around the forum

Maybe go to Bunnings and get some different sized washers.. haha, just kidding

have you got a quote from whiteline for these? Group buy?

I'm now curious as I've never heard of these things. Can you please tell me what the go is? Take out toe in on the rear? Why would we have toe-in on the rear?

First of all I have had several to & from emails with Whiteline with no result except that they aren't going to make any, even offered to get numbers of interested parties, but Naaa.
Secondly the Polo GTI has 3mm rear toe-in on each side.
Just have a good look from the rear & you'll see what I mean.

Hoyhoy.

At least Whiteline answered my emails, not like some others.
K-MAC.= nothing & if one day they do decide to answer then I will edit this post.

Ah, me got an answer from K-Mac concerning another matter, just took a while because they were relocating, so me EAT my words.

Eddy, try GT3 -- he had a set of these at one stage.

Toe in on the rear lessens the tendency for oversteer.Manufacturers generally set cars up for the great unwashed ie understeer.
Having said that,I had a set of the Whiteline shims on the rear of my car.
Couldn't tell the difference on Track or Road.....

Here's my experience with them (posted on an older thread):

For those interested - here's what happened...

My combined rear toe-in (total) has been measured up to +10mm (more recently +7.7mm on a different machine). With the WL rear shims installed, it toed-out the rear by -5mm total, ..massive reduction (WL advertise "up to" -3mm). This mod is a mixed blessing and I'd advise caution in using them, depending on the type of driving you do.

Pros - feels balanced (neutral), better composed and more responsive, eg a lot faster entering straights, vastly improved straight line speed, acceleration and steering responsiveness (with less understeer). Also results in more even tyre wear.

Cons - toe-out makes the rear of the car more unstable in corners, even though there's less understeer. If you track your car and/or take cnrs at very high speeds, the shims may not suit you.

If the shims could toe-out to -2.5mm (rather than -5mm) then they'd be perfect, but they don't so be weary.

Thanks Maccaa and GT3, exactly what I was curious about.

cheers

Well then can anyone find out any data on these (whiteline wouldn't) just the thickness from one end to the other will do for now. So I can muck about with getting some made & after what Neil has mentioned may be not as savage. I will also look at getting extras made.
P.S. Me want.

[seangti]

Eddy, would you mind elaborating on the rear tyre wear, as in how bad?? Is your suspension stock? Is it a result of mods?
Or PM if it's too far off topic. I'm tracking mine this weekend, it's all stock atm, but got H&R springs awaiting my pick-up

[Eddy]

Hoyhoy.
Well my suspension is changed & on the track the rubber just peeled off the rears while the front was ok & this after dropping the pressures several times, can't say any thing about standard set up, haven't been there.
You might find that your set up will be ok as is.
P.S. Me also a fussy bugger.

Hi Eddy,

If you can work out the width of the plate (maybe measure the spacing of the bolts), then compare this with the diameter of the wheel, you can work out how much toe-out you will get by varying the thickness of the plate..

E.g. of the plate is 100m wide, and the wheel 600, if the plate is 1mm thicker at the front, you'll get 3mm toe-out (assuming you start with 3mm toe-in).

I reckon you should get a few sets of plates with different thicknesses made up at the same time. Maybe you could also vary the thickness top to bottom to change the camber? (assuming you felt the need to do so).

Feel free to correct my maths if I've gone awry.

Cheers,

-Phil.

I'll keep this in my mind, Ta, Phil.
