I own a slash and want to lower it with shorter springs. I was told that the Jato springs and Proline springs were the shortest. From what I've found on the internet, the Proline front springs are 42mm (1.65") and the rear springs are 58mm (2.28"). I couldn't find any specs for the Jato springs so was wanting some help from you guys.

By the way, I'm running on a dirt oval....no jumps. That's why I'm looking to lower it!
