The FC3S can use some negative camber on the front wheels for better cornering
performance. The MacPherson strut front suspension system likes some
slight negative camber for better traction. Unfortunately, getting enough
negative camber from the stock suspension parts is next to impossible. You
can rotate the stock upper strut mount for 60' of negative camber, but that's
only ½° of additional nagative camber. Track alignments can use
up to -2° to -3° of camber up front for efficient traction; stock
suspensions can only maybe dial in -1° or maybe -1.5° of camber up front.
Fortunately, aftermarket front camber plates can help. By allowing relatively
easy front camber adjustment with just some hex keys or wrenches and a hammer,
you can dial in all the camber you need within a few minutes. The beauty
of this system is that you can run "street" camber for the street for best tire wear,
but run more aggressive camber on the track for best traction.
Most of the aftermarket front camber plates replace the front upper strut mount, so
check the instructions carefully. Cusco is one of the more popular brands
from Japan. JIC also offers front camber plates for the FC3S.
Most of the Japan coilover kits offer adjustable front camber plates on their
suspension kits. Brands such as Tein, Cusco, JIC, HKS, A'PEXi have coilover
kits with integrated front camber plates built in. So if you're looking
at one of these, getting front camber plates is redundant and unnecessary.
