guys i got a car currently built for autocross (on going project)
im wondering if a c pillar bar would be helpful in the build?
heres the bars that is intalled so far:
gab front strut bar
cusco rear strut bar
cusco front lower control arm brace
But come on the braces he has goin through that box look to go through a hole and not actual mounted to the points where as the c pillar bar is bolted to the pillars/ seat beat bolts and not have 2 holes drilled through the car and the bar sticks out either side.
after seeing that vid i still think a c-pillar and a rear strut brace especially a 3-point do some difference to handling as i've experienced when i had my glanza and had both installed. although a six point would be the maximum you can get from rear braces. using that theory in the vid even the front strut brace is useless then!!
