It's already fitted with vented discs

If you mean cross drilled or slotted, slotted are supposed to help clean the pad surface whilst braking (as well as increase surface area for cooling).
Cross drilled brakes just cool slightly better - there's probably some surface cleaning benefit, but just superficial.
If you're going to experiment with different discs, try Adams Rotors.
I think a lot of brake issues stems from people habitually braking late and heavy because of the stress involved in heavy traffic and simply because the car has good brakes. Hard, late and heavy braking will suddenly heat the disc surface up and lead to uneven hot spots. Longer gentler braking will more evenly heat the disc surface and keep it cooler.
I think the choice of pad is important too - I always select a good quality ceramic pad.
I have never had a warping or juddering disc problem with my cars
