Theres no buzz if you leave the lights on anyway, wasnt on the car at the time.
try pushing the drivers side courtesy light switch a few times by hand, if it dont work, remove the switch and pull out, check the plug behind the switch isnt rusted, clean it if so.
koni adjustibles, just change the height by using the key that comes with the kit.
Yes you can get HID light kit for the car, someone on here has done it.
3 point harnesses, i got sparco on mine. you need to mount as follow
drivers seat)
point 1. this goes to the seat belt lower bracket which runs from the rear passengers footwell(long black bar which seat belt is looped onto)
use the bolt hole provided.
point 2. this goes through the recaro seat head rest and seat itself.
pull the rear seat bench upwards and climb over the seat. you will see many bolts and brackets. use one that is roughly straight behind the drivers seat.
point 3. This goes to the front seat belt point in the middle of the car. unbolt the seat belt point and remove it, simply bolt the harness UNDER THE SEAT BELT POINT. the bolt is long enough for all 3 points to be used.
passengers side is the same as above, but point 1 & 3 are different, use point 1 for the centre seat belt point and point 3 for the black bracket in the rear footwell.
