Hi everyone I am a newbie to the site and I will be taking delivery of my first ever VW next week. I have bought a Polo TSi and I have planned on 3 things happening to the car within the first 2 weeks.

1. New rims and tyres
2. Lowered
3. Performance mods (ecu tune)

My questions are:

I am looking at some 18 x 8 rims and tyres, what type of lowering would have enough clearance for no scrubbing ect. I want 18's because I love the look of a bigger wheel on a small car.

What tuners can tune the car without effecting the warranty?

Located in Melbourne if anyone can help that would be awesome.
