In stock classes we are not allowed to change the offset of the rims by more then 6 mm. And I would not want to because I can drive closer to cones then other cars because the Insight's rear wheels have a narrower track.
And a "loose" rear end is good for autocross because it allows the car to rotate better. I set up my car to rotate during an autocross by putting 42 psi in the front tires and 26 psi in the rear tires when i'm using 185/60R13 race compound tires.
Your mod will increase the stress and reduce the lifespan of the rear wheel bearings, bushings and possibly other suspension components.
Your english is fine, i've seen people write much much worse even though their only language is english.
