Oh sorry, I put the aluminum clutch shoes in and BAM! fixed. I ran all day and the SG still looks like new. The stock clutch shoes are just not made for the big block engine.

I called HPI and tried to get them to admit it but all they would do is send me a new SG (so I've got a spare now).

Now I've got to get my shocks properly bled. I had no idea air in the shocks were a problem.
