[maranello]

i know it will be fine as long as you put the stock parts back when u return the car like aftermarket rims, exhausts, etc...
but what about add-on lip kits? i was thinking about getting either Hamann or ACS kit, but will dealer b*tch about the holes that got drilled during the installation underneath the original bumpers?
and anybody happens to know what material Hamann and ACS make their kits? poly urethane or fiberglass?
thanks in advance
