how to determine the size of tires on P5? 195/50/16 seems not easy to find. learnt somewhere in the forum that we should go with 205/50/16, since it won't throw off the mileage like 205/45/16. is it true?
Is H7 the right size for low beam?
should I stick with the big names? i.e. $150 or more per pair. Or can I just buy some no-name bulbs which may last as good as those expensive ones.?
what's the safest way to replace the bulb? And how do u replace the low-beam on the passernger side? Cos'...
