I haven't noticed any difference in steering.

When I first modified my car for better performance, I noticed that it would flip fairly easily going into a turn, so I started running the regular wheels inverted, or mounted backwards on the axel to get a wider track. I have been doing that for a while and didn't notice a problem turning. Now I'm running these wider wheels with the "melted tie rod" mod for better turning, so maybe they've cancelled eachother out?

my mods:

Orion Elite Stock Motor, unmodified
20 tooth Pinion
AWD
Modular Fifth Cell mounted behind the rear axel
Replaced stock wires
Replaced stock motor connector with Deans Mini Plugs
Melted Tie Rod 0 degrees
