Anyone know how to DIY a spring stiffener? It is used in between the spring to make it more stiff... to improve braking and handling. I know splitfire is selling but too ex.... around S$80/pair.
To all the sifus out there, im just curious wat r the main causes of an oil leak from the BOV. It squirts a bit of oil and the engine looks really messy. Btw im using HKS SSQV. How do u rectify it? Need your inputs...
