The concensus is that they don't actually do a lot, are more cosmetic and a real PITA to fit, but if anyone is in the market for them they might be worth a punt..... I was outbid at a tenner as that's all they are worth to me. not sure if the fixing bushes and screws are included or how high...
Does anyone know if these TTM scoops or similar fit my CLS, or if someone has a set and does not mind sending me a drawing I can get a test set knocked up
