Has anyone with an 06 STi had just the tracking checked and adjusted to successfully reduce the tramling you get with these cars? I checked with the dealer and was told it was within limits.

When I test drove an STi I was aware of the tramlining but did not think it too bad. Now I have an 06 and I find it very tiring and potentially dangerous in tight situations.

Subaru alignment tolerances are huge and allow the dealers to do next to nothing to get "within limits". Go to a specialist and have it done properly. (Scoobyclinic, TSL, Powerstation and the likes).

What tyres have you got?
Not 070's by any chance. I had these and the tramlining became more noticable with tyre wear.
I found the fitment of Michelin PS2's to be a good solution.
I had prodrive allignment settings with the 070's and still had a lot of tramlining, so I don't know if allignment is the issue. Dialled out heaps of understeer however!:)
On the safety issue, it certainly makes you keep two hands on the wheel!

Add some air to the tyres, this will help loads. In my 17's I run 36psi front and 34psi rear and recommended by Whiteline.

It's definitely the RE-070 tyres that are at fault. Very firm sidewalls mean they follow every camber change in the road.

Prodrive springs will help a lot, as they seem to smooth out a lor of the minor bumps on the road, so you'll get much less pulling.

The re070's do this, I fitted some on my 03sti and it tramlined more than before-great tyres but abit extreme. Got some michelin ps2's now and the tramlining has all but gone, simulat grip though.
