J,
Yes there will be a dedicated webpage for the “Ipanema Top Speed Club” contest on the site. It will have information & rules for submitting entries; just need to get it put up before the end of this month.
The contest starts on September 1, 2013 and ends on September 31, 2013.
The contest is open to anyone running a Warrior body on their cars, except for our sponsored drivers; as they already receive free products anyway. This contest is strictly for our Warrior customers around the world.
On rear diff oils, I believe I read that johnracerx runs grease in them; you’ll want to check with him, but I seem to recall something like that. What does Chris use?
