Right I've been searching this thread for the past hour or so read about shocks/springs (guess what I'll be dreaming of tonight!!

)
Any way was reading reply 3378 and it was mentioned that 3 set of springs might be needed
So my Q is, would
all the springs out of these 2 set be different stiffness's? or I get just 53440 set (seeing as there's a extra spring!)

Tamiya (#53440) On-Road Turned Hard Spring Set
Thanks in advance guys
