All that sounds good. DON'T add a spoiler. It's stupid to add a spoiler to FWD car! Instead, invest in protecting the car, like spend time on washing and waxing the car PROPERLY. Maybe if you want, youcan opt for a fromt splitter. A good investment would be to change rear drum brakes for disc brakes. If you do consider this, DO IT FROM A GOOD MECHANIC. Personally, I'd reccomend Total Quartz 9000 oil, Honda genuine air filter, and Leppon oil filter. I personally us Total petrol in all my vehicles and it does preform better than others like PSO and Shell (minor difference, but Total pumps usually have good service and good quality petrol, that's why there is always a rush there). I would also opt for a decent HID kit. I wouldn't opt for LEDs because in my experience, LEDs in H4 size usually suck. If you do get HIDs, get them from a well reputated brand and do adjust them properly, or else you won't get optimum coverage and you'll blind others.
