Current shock setup is Front: 6 hole mip bypass piston, double clear valve, 3x1.35 3x1.45 holes, 700cst oil, 4 dot front springs. Rear: 6 Hole mip bypass piston, clear valve, 3x1.45 3x1.5 holes, 750cst oil, 3 dot rear spring. Car feels too bouncy and does not settle down after hitting bumps. Car front flips off jumps with blown out faces.

First check and bleed all four shocks, then make a small damping change to the front only if they are air-free. A bouncy car that keeps oscillating after a hit may need more damping, but increasing damping too far can make it skip across rough bumps.
- With the springs removed, compress each shock and listen for a squishy or whistling sound. If you hear air, refill and bleed it. Also check that the suspension moves freely and the shocks are matched in length; those checks are particularly important on the XB8E ’25.
- If the shocks are consistent but the front still rebounds or kicks off the jump face, try slightly thicker front oil, keeping the pistons, valves, springs, and rear oil unchanged for the test. Your front piston already has relatively large holes, so changing oil first makes it easier to judge the effect.
- If the car still bottoms or kicks off the jump face, more damping or a smaller-flow piston can help control compression on jumps. But if it starts skipping over bumps, back off: the off-road guidance favors lighter damping for bump stability and heavier damping for jump control.
Make one change at a time and test the same section of track. A front flip in the air can also come from throttle input; adjust throttle gently while airborne, since throttle changes the car’s pitch.

the rear is more of an issue than the front

Got it. Focus on the rear shocks, not the front. After checking and bleeding them, if the rear still bounces or keeps oscillating after bumps, try a small increase in rear damping by going slightly thicker than your current 750 cSt oil. Keep the piston, valve, spring, and front setup unchanged for that test.
First make sure the rear shocks are air-free and working evenly: XRAY recommends listening for a squishy or whistling sound when compressing them, and refilling and bleeding if you hear air. Also check that the suspension moves freely and the shocks are the same length.
More rear damping can help control the chassis on a blown-out jump face, but too much can make the rear skip across smaller bumps. If it starts losing grip or deflecting over rough sections, return to the previous oil rather than stiffening it further. Make one change and test the same section of track.
