im thinking of changing the spring, i wanna ask you guys if i change the spring for my almera,the warranty will stop for the spring only or for the whole car?

hi guys, im currently driving a nissan almera. bought it about a month ago, im thinking of lowering the car, my question is if i change the spring(which is lowering my car),will my car's warranty be over or just the spring(stock)'s warranty is over?

has any almerian think of changing rear drum into a brake disc(which has brake pad)? anyone? is it possible?

thinking of changing the spring tho. make it lower abit. the gap is too big

perhaps you should ask those pros, asked wouldnt mind to tell me right?
