Wow.. you really spend a lot on your perdana..Well my setup was simple;
Anti roll bar front(16mm) and rear(19mm)
Front top 2 point strut
Rear boot 2 point strut
Stiff rings(front)
GAB Type SS
Now only thinking for Fender bar..
Even the stock front anti roll bar, you also change..
Since your front is smaller compare to your rear, your car is already over steer. How is it like in terms of experience and handling
