You had a lot fun! Envy...
I presume these yellow springs are the S***parts heavy duty's one from Paddock. Why dont you try the Bearmach blue ones? The "offroad" type, not heavy duty type. They are softer so more articulation is expected. Then you'll need wide angle props and straps or cones
They(bearmach) also offer 3" kit. Then you'll need castor correction chalices and double cardon props Oh and dont forget polibushes
Followed by bigger tires, HD shafts,HD CV joints, higher diff ratio, then diff locks...
Cheers!
