G'Day all,



This is something I'm also considering, wider rubber on the rear wheels

that is. I currently have 205/45 16 all around and have major wheel spin

problems if launched with the intent of accelerating hard (without side

stepping, you can forget that). Has anyone run 225 on the rear? I'm about

to lower the car so experience with this size and a decrease in ride height

would be appreciated.



On the upside no rubbing anywhere, even with the steering on full lock.

Before anyone asks I can't remember the offset of the wheels but will find

out if anyone really wants to know.



Matt.
