so i see i could still buy a red spoiler. now.... it's vanity right? - it will not make a jot of difference to how the car drives? and if i am so vain, how does it fit? - does it require screwing, glueing? -clipping on? wary to do anything that permanently alters the car.
bolts on. you won't notice anything in the driving. I might knock 0.1 mph off your top speed as it will create more drag. It will make the car heavier so reduce 0 - 60 time buy 0.05 of a second. I'm making the numbers up, it will affect it but you won't notice it, negligible.
Spoil! er. I think the spoiler spoils the cars appearance, too big. I've seen some on google images that have got a smaller spoiler which looks sexier!
