Martinmac has a bigger spoiler on his. Its hard with the roadster due its rather large backside, the shape of the car totally changes with the roof up to the roof down. I generally like most of the spoilers on the roadsters with the roof down but I don't like the same ones with the roof up. Thats just my opinion though. Sure you will like Martins though as it is very nice roadster. Everything on Martins compliments, the kit, wheels etc. Probably best one I have seen to be honest.
