[finch wxm]

I bought that Purple series one for the Dogbone Mount and also the front wishbones.


I'm running KW Variant 2 Coil overs and AST Solid Top Mounts .

I see they do a black series now ? Are they harder again ?

Also any good starting set up , What camber shims etc and anythink else to buy ?

I have ordered a rear roll bar
