Couple of YZ-2 Setup Questions

[dibble34]

Ran mine for the first time yesterday at TORCH. Was pleased, but the rear was a little loose. I was running Lee's setup from TORCH, with the only difference being i had the geared diff in with 3k oil.

My first question is would a ball diff of helped with the rear traction issues i was seeing?

2nd Question is about springs. When it gets a bit dryer i think i need to get harder springs, but i am confused about which ones to get. Can anyone give me an idea of what i should get for a dry astro track?

Cheers

Dave
