Waslam brother.
As per my last conversation with Suzuki Riwand Lahore, the warranty will void for sure if we install camera or speakers in doors because that would clearly mean mingling with wiring of car.
Since Pak Suzuki doesn't produce these parts and you would go for aftermarket then they will not accept your claim if anything goes wrong.
About tyres and rims, they said it would directly affect car's suspension so it isn't recommended either.
This was my research that I did in regards to my VXL.
