I'd also like to know! ( I've read every page of this thread and don't recall an answer)

All I know is wider offsets definitely helped in 4wd short course. Truggy class is by far the easiest thing I've ever driven and I'm pretty sure it's the longer wheel base / wider track that makes it so stable.

I have a full set of 2mm's on the way from Tower hobbies and I'm curious to see if I lose any traction or steering. Both of which can probably be "tuned" to accept the wider track while adding stability.....?

I'll let you know how it goes.
