Just finished re-building our diff, we put in a new aluminum anodized diff gear and replaced the idler gear. Fired it up in 10 degree weather, BBBRRRRRRRRRR[X(]! cruised around to get warm then did a little fine tuning on the high speed side. Then I did a couple of high speed passes pulling some killer wheelies then ended up going over backwards and busting the back shock tower into 3 pieces[]. I always knew plastic and cold don't mix, But for $3.99 I'll be back at it again tomorrow. You gotta love that!

It didn't pull wheelies so easy before. Could it be that the diff is to tight?
