hi i have a 1985 nissan k10 GL and i have just put on some 195/45/15 TSW razor alloy wheels. the rear suspension is very very soft and even if i sit in the boot the arch more or less touches the tyre. i have seen on buypartsby that there are KYB oil shocks and can i use these with some larger bumpstop to stiffen up the rear suspension. the car is not lowered, its just got standard springs but at the moment i cant even have a passenger in the front seat without the rears rubbing on corners. thanks adam
