I think the inside wheel spin on A6's is partially caused by them being much shorter then stock. So bad understeer eh? Iirc the Hotchkis is a pretty big bar for the 370 over stock, that might cause some understeer, but I'm betting still a worthwhile mod. Without shocks you're just going to have to drive around it. But one important factor is what tire pressures were you running? I noticed a feelable and drivable change on just a few pounds of difference.

The Hotchkis front bar will cause pretty bad push as it reduces the body roll generated camber. Unfortunately I don't think there is much you can do to add static camber up front in stock class.
