Good day, everyone. I have some questions and in need of answers.

1. After stopping for approximately >12 hours, my rear tires will produce a loud "KTANG" sound once the car started moving forward. It sounded like something just got unstuck. The phenomena does not occur again until after the next long stop. Is this normal?

2. The power socket (port where people put phone chargers, etc) is broken. Is it costly to repair?

3. My car is currently stock and I'm thinking of starting to do modifications with it. Where should I begin?

Thank you.

Mine is the Elegance model. Will de-cat and changing extractor increase performance / FC?

Alright. I'll do some research on the matter first. Thank you.
