I dont have much trouble at all Big P plates on the back and front of the car does the trick, alot of vx 255 ls1's try and go me which is a nice old luagh, and alot of skylines try as well, couple of wrx's only been chopped once, when my car was stock and I had it for 3 days I was on the freeway and an XY GTHO 351 was up my arse, slowed next to me and we both went, it was pretty much neck and neck, he only just got about half a car length in front.. he was about 60 years old too lol, thumbs up though
