Alot of that wont do much as for as warrenty claims go.
A LCR front splitter is relatively easy,
Tints - Id get done by a proffesional so its a chequebook modder moment
Lowering - 40mm seems to
help, but the back is high, id go lower (and have

)
Seventeens - Changing wheels is easy, 17's fit nicely (esp if lowered)
Back lights - Will look cool dont think ive seen any beeza's like that I know one took the red part out of the back, that looked ok.
Rear wiper - Has been done before, aint a clue
how to do id, id imagine take it all off and get a cap?!
Air Filter - Easy, take a look under thre 1.4 Polo if you cant find owt for the beeza!
Most of all, enjoy the car
