Just got a TT 225 Quattro rack off ebay from a 2004 model for £85 + postage...Bargain! Hopefully get it fitted soon and have nice tight steering once again! Might get ARB's done one time as the subframe is dropped.
Physical dimensions and fittings are all that concern me...I want less turns...thats a good thing! My current rack is ******, and has a massive slack patch in the middle... means that the car can do what it wants when there is no tension on the steering...not nice!!
On the racks, there are 2 bolts on the drivers side which bolt it to the subframe, and then the other side has a bush around it, and a 'U' bracket which bolts to the subframe... There is no need for it to be different on the same platform. Im sure it will be fine.
