question about lips and wheel sizes Options

[daazndood]

hey people, your n00b(thats me) wish to ask a few questions

first of all, i was wondering:

how the hell do you connect a lip to your car? i've never had one and have never seen anyone put one on. i always wondered this. do you just drill and screw like crazy? is there precut holes or something? or do you just put glue everywher and hold it in place for a few minutes for the glue to dry?

also, would wheel size change how many miles you put on your odometer? for example, if i stick 24 inch rims on my car and drive hella far, would the same amount of distance be calculated on my odometer then if i had the stock 15 inchies?

thanks in advance!

i know that rims size changes your actural speed but never thought too much on it. i made a fast calculation like below..

stock rims are 215 50 16r has 159.5 cm circumference
my rims are 225 40 18r has 169.7 cm circumference.

that means i am actually going 106.4 km when i see 100 km on speedometer.
can anyone correct me pls?
