RE: Official RC10GT Thread
It's hard to say from the Net. From here, it looks like a triple at the end and I would try that? A lot depends on how your truck is setup and that you might need to rhythm jump the section to get through the fastest. Sometimes it's faster to slow down and make it through with out crashing since crashing will cost you more time.
Watch the local guys and see how they are doing it.
Plus, if I remember right, you have a lot of aluminum and a .18 on your truck. That will make your truck heavier and aluminum a-arms with the un-sprung weight tends to make truck not track worthy. If you’re going to be driving a lot of track driving, I would recommend the stock a-arms. Even the RPM ones aren't good for tracks. They flex too much and make the handling inconsistent and sloppy. If all you do is bash, then RPM and Aluminum arms are ok. I have a similar section on my track and I raised my ride height a bit and it made a world of a difference.
