I run 5-7-2 at my track with no front sway bar, 40 shocks all around with mugen grey springs in the front and softer blue springs in the back, I will adjust preload spacers as necessary. We have a huge jump like that in your pic except for the HORRIBLE wooden sides, dont screw up and misalign your jump or say good bye to your A arms. You may want to stiffen up your sway bars because those little chicanes are going to be tough if your pushing on power. Looks like a lot of those little triples and doubles are quite steep, so you may want to mess with your shock fluids and stiffen them up a little. I like my buggy real soft, you may be different. I like crimefighters but if they are running wet then bowties may be a good choice to keep the clay from globbing on and making slicks.
