dude, the servicing is important...
May i suggest, the brake pads u only change them when needed too. N when u change those pads, go for a better ones, u cheap ones will tend to make u change them more often.It depends on how u use them, u drift more, u change often..
The servicing part, if ur using Turbo's, then change them regulary like once a month, this also depends wheter how u 'lenjan' ur car..the gearbox and LSD oil, change them like once evry three time u change ur change ur black oil..LSD oil is very important..
I may be wrong...
cheers'
