any shock is better than the factory suzuki gives.
i changed my shocks about 5 or 6 times in the rear. this was with and with out spacers fitted.
anything that mounts up right will do, although some people have said that passenger/sedans shocks will not hold up to the vigors of off roading, and the constant movement through its stroke. have yet to happen to mine.
when i didnt have coil spaces, i used a shock that was 590mm extended, then put on some other shocks that were 610mm extended. with the longer shocks, i could remove the coil at full droop. not good.
i put a 1" coil spacer in and the coil was good.
then i got some other coils, which lifted the back of my vit 2", were softer than the factory, and i then put some shocks that were 630mm extended. the coil only just drops out of the top seat at full droop. very good.
i have also found that the GAS charged shocks were real stiff, and game me a head ache when i drove in town. i guess the valving was for a much heavier sedan.
then i found some factory ones off a holden commodore, the were oil filled ones, and these are the ones i use now.
i can get pics for ya in wanted.
hope this helps.
