For my experience, my previous Toyota Vios 2nd gen installed the following items:
UR Front Strut Bar
UR Rear Anti Roll Bar
APM Sport Suspension for front and rear
Continenal UC6 Tyre x 4
The driving experience and handling is awesome, high speed cornering is never a worry.
Rainy or sunny day, i drove with same speed, thanks for good tyre by Continenal.
Yet, the car got a bit bumpier compared to original Toyota parts.
