I really need some advice about my car, as in this town no one really seems to know anything about suspensions. I have a 2.5tdi avant, non-quattro and I noticed that the rear tires are worn on the inside. I went to a suspension garage and said that the rear right wheel is tilted on the insed by 1 degree off the limit. Being a axle and not independent suspension, they said that the axle is bent and needs replacement. I went home, put a 16" wood on the rim and with a spirit level I measured the distance from the top of the rim to the leveler and compared the two rear wheels. Both wheels sit on the ground at exactly the same angle. Now I believe that the workshop didn't measured correctly, but the wheels are still worn off on the inside. So, my logical thinking is the wheels are sitting on the ground more like an "A" than an "H". My next step was to check the coil springs color code and found that in the rear, I have yellow + brown, and according to AUDI A6/AVANT [A6] (EUROPE) 1998: REAR AXLE: 51110. SUSPENSION; SHOCK ABSORBERS that color code corresponds to sport suspension. My question is: If I put normal coil springs instead of sport, will my rear suspension geometry will be affected? Will it be more like "H" instead of "A", thus wearing the tire more evenly?
