my roof is on a trolley too, these really are worth the money, like you i have added some padding where it restes on the roof, i also have sp+ome passing on those spikes, they catch my knees every time i walk past it........
Thats a really good find especially in same colour, i love mine on, but in summer its off for obvious reasons, but i winter store my car with hard top off and soft top up to save mold and window creasing....cant win..
