    Rear toe adjustment on S3's

    Those who have had their rear toe adjusted on their S3's could they get their wheels to sit straight ahead, or what is the lowest toe you can get?
    Whilst driving to ADI, I noticed a light scraping noise when the rear suspension was moving up and down. The alignment guy told me I had reach the limit of toe on the driverside, on close inspection, I can see the trailing arm catching slightly on the edge of the sideskirt, the inside part where you don't normally see.

    That can't be normal right?

    If you're running minimum rear toe-in (whatever angle that is), then that'll loosen the rear of the car. Your lairy moment at ADI may be starting to explain itself...

    Do you know what rear toe-in you're running?

    Did they get the thrust angle bang on? the subframe maybe slightly out?
    Try measuring tyre to arch on both sides to see if it is different...

    Minimum on one side and the otherside to match, it was still some way off factory toe, and the rear is more stable after I had it adjusted Paul.

    Oh, the rear subframe can move side to side aswell like the front? The driverside had one more degree of adjustment of the driver side, this could be answer!

    Cheers!

    Rear toe can be dialled in with a combo of the adjustable tie bars and undoing the bolts on the swing arms (4 bolts to the body)... I managed to get mine to zero toe... dunno about the rear subframe... plausible it can be shifted

    Yes Paul, I've had thought about it technically, and putting the tie bars on the bottom would be more ideal for correcting the Toe vs Camber, but I have a set of Dave's stainless steel items, and the Xenon level adjust bracket won't go round it, they are a bit chunkier than the OEM bars, so fitting them to the top is the only option, which means more toe. I could however modify the bracket to fit, I would need to fabricate and extra bit of metal, so some things to think about.

    Jo you can fit the xenon adjuster to daves tie arms, i have, ive got 2 sets so had no choice, i just used some thin mild steel and moulded it around the lower tir arm then just drilled 2 holes through the metal and bolted it up tothe xenon adjuster arm, works a treat.

    My wrong wheel drive A3 runs silly amounts of rear toe in, killing any decent handling at Birth.

    I'm looking forward to seeing how it changes it when I finally get round to fitting all this new kit I have, 2.2 degrees rear camber and parallel toe coming right up

    i thought the s3/a3 quattro had rear toe in anyway it was they way they were ment to run. i maybe wrong. im running 30mins of toe in on the rear of mine and also have rear tie arms and polybushed the rear subframe is bang on both sides and have just changed the passenger trailing arm as the old one was way out showing 1 degree and 10 mins. it also depends on the height of ur car and camber to reduce the toe. my rear set-up is 1.5 degree camber with the car lowered roughly 60mm and had no issues with tyres at this toe angle.

    surley some toe would help the car handle better in corners also.

    Which way though? Think about it

    if you have toe in, when you turn into a corner, and load up the outside wheel, if that outside wheel is toe in, it'll try to steer the back of the car the opposite way to the corner, so you need more steering input.

    Toe in induces understeer, but helps keep the car stable under acceleration and braking.

    Toe out induces scary Oversteer, and also makes the back end pretty wild under braking.

    Many race cars will run rear toe out. It's quicker, it much harder to drive.
