autocrossing new wheels? - Mazda 6 Forums : Mazda 6 / Mazda Atenza Forum

bluepred · 08-08-2004, 08:12 PM

I autocrossed my car once with the stock 16's and once with Motegi mr7's, the offset went from 55mm to 42mm. While I like the aesthetic change pushing the wheels and tires in line with the body of the car as opposed to further in the well, I am not sure I did not mess with what the magazines say is a very good Mazda 6 suspension.

The first time I ran (note tires are the stock michelin's) the car seemed very tight with no understeer or oversteer and seemed to grip the turns much more, while the second time I ran with the motegi wheels and smaller offset the car had much more movement with the backend coming around on me MUCH more. I even spun the car 180 degrees. (fun)

Any thoughts would be appreciated. Did this happen because of the new offset...the higher tire pressure (32 to 42) or just a more wide open course (more ways to get into trouble)

I am going to ask this in the autocross section as well.

Thanks.
