Okay....I had chg adjustable before so I think the stiffness will not stiffer then adjustable?
My adjustable spoil quite some time so I just change back to stock abs. But after sometime due to my very bad driving habit stock one also gonna die soon.
So I was surveying GAB SA,APM perfomax,D2 heavy duty abs I saw GAB SA & D2 heavy duty can use back stock spring so I am quite intrested.
Is it possible to use back stock spring match with Apm Perfomax abs?
u can use normal spring with performance abs or performance spring with stock abs but the absorber wont last long.
Stock absorber cannot cope with the bound and rebound character of sport spring and same goes the other way around.
Not sure if heavy duty abs works well with sport spring.
What is suggest is you set your goal.If u want better handling,go for sport abs and sport spring, sacrifice comfort..a lot esp in small light car as most of the time the spring rate is just anything the shop sell to us.
If u want reliability then go back to stock.Bear in mind that with time or abuse,even the coil spring will wear out hence i suggest replacing the spring as well if u havent do so.
