i dont really know about anyone else but i have 17" Sacchi rims on my 99 SVT and whenever i even have at least 1 person in my back seat (mainly 2) and we hit like a dip in the road the car will slam on my Michelen Pilot Sports! I dont know if anyone else has that same problem, thought you wanted to know. I haven't met anyone with 18s on their SVT though so i dont know how it goes with 18s
