I use the street Jam shocks.
They have two types:
the stock ones with a through shaft no bladder like the f104v.2
option shocks with a bladder
they also have option gold shafts and option machined pistons and spacer
all the plastics for the front end are the same as the stock Speedpassion car
I swapped to the sp carbon 'b' knuckles and carbon servo holders
I left the front upper and lower arms stock as they are the best for asphalt. If I ran on carpet I would go for the carbon arms
