i got a 99 audi a4 2.8 quattro and i'm about to go up to the mountains. I heard that there is a certain power ration between the front 2 and back 2 tires. I was wondering if i could change it....yeah sounds kinda dumb but i have no idea...my front two tires are basically bald and my back 2 look new and they were all new tires to begin with....Thanks for any help dudes!

 

The B5 quattro system diverts up to 69% of the torque to the rear wheels under acceleration using the torsen center differential.

 

you can't change the ratio. You can however move those back tires to the front for a little more traction. Best you can do besides buying two new tires.

 

Oh and the ratio isn't gonna make them wear differently they do that because of turning.

 

You can replace your center diff with a STASiS one and that will change the ratio to 80% rear.

Your front tires are bald because Audi's have the worst weight distribution and your car understeers worse than a Scion tC. I suggest you learn how to compensate for that with better driving before you go rebuilding your drivetrain.

 

yes you can change the ratio. the stassis diff is one way. another way would be to put thicker washers in the center diff. manufan made them for somebody. the thicker the washers, the more torque to the rear. and like clx said, you should drive differently.

 

how about rotating the tires every 3-5k. Better tires would help too.

 

i taught the stock center diff (b5)would send up to 75% of torque to the back??
and isnt stassis up to 89% to the back?? idk its something like that!

 

there is a way to do it. But it will require to take the central diff out the tranny.
What exactly do you want to do, more bias or less bias (more or less power to the rear?)

 

Hiwords is right on the mark - shimming the center diff can change the front/rear torque split on the car. Manufan made a set for a guy on the Zine so he could make a much-more-rear biased setup. I'm seriously tempted to look into that - I love the idea of, say, a 20/80 split
