Whiteline rear camber adjusters

[GT3]

I've come across this bulletin from Whiteline on their rear camber adjusters for the Polo:

Has anyone come across these and/or used them? Probably more relevant to Polo GTIs that have been lowered, eg suspension kits, coilovers.

It would be worth giving Whiteline a call. I think the story was that early on, when they were developing the RSB, they noticed quite a variation in rear alignment, and developed these shims to correct this. I don't think there's a problem in all cases but, as I said, give Whiteline a call. Oh, and you might want to get your rear alignment checked, too -- if you think that's what caused the wear problem. I think I posted up the stock alignment specs according to my steering guy somewhere

Little bit misleading this one.They're actually toe adjusters for the Polo,not camber adjusters.According to Jim at Whiteline,a lot of Polo's had excessive rear toe in-some around 9mm!
I've checked mine and it's around 3mm toe in[pretty much all on the left side]so I haven't worried about it.Any more than 3mm and it would probably be worth fixing.
First thing to do is get a good 4 wheel alignment and see what your car has,before rushing out to fix something that may not need fixing.

Thx guys, .. just interested in why WL developed the adjusters.

My rear toe is way out, it seems the WL toe adjusters are the only way to rectify that. They should improve overall balance and rear traction too. Will report on developments.

My rears are out by +5.6, it seems the WL toe adjusters are the only way to rectify that. They should improve overall balance and rear traction too. Will report on developments.

What do you mean by +5.6?
Most are toeing in by up to 9mm[according to Jim at Whiteline]
I was lucky-mine is only 2 or 3mm toe in.
It may aid turn in a bit to reduce it,but 3mm is OK by me.
Rear grip isn't our problem,anyway.....

According to the alignment spec sheet I got a while ago, there are two measures -- total toe, which measures the difference in mm from 0, and the individual (LH/RH), so my "before" Total toe was +3.3mm, (LH 1.5mm, RH 1.6mm), after was +3.5mm total (1.6/1.9) with Camber set to -1.44 degrees each side

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.
