RE: Introduction to suspension tuning including 'Pack'.[Stadium]
Well you'll want a lot of pack, but also a stiff package anyway, if you use full downtravel you can still have a lot ride height without breaking your car as the suspension will extend to full length in the air anyway, so don't worry about having to have it high.
Go maybe a bit smaller pistons than stock and 50 weight oil. This should result in good handling and the pack required for the skatepark jumps. if it isnt stiff enough for you still use smaller pistons not thicker oil. then you have more pack.
