I have the original ACS front and rear lip (not replica). Before I get them painted, i spoke to a local shop and he said that installing them with 3M tape or the bonding glue that comes with the kits will not hold for long! If you have an ACS lip and drive in winter, what has been your experience? Does it fall off in the cold? Crack? He said that he can remove my bumpers and install them with hidden rivets to hold it on, but I think that is not worth the hassel! Your feedback would be great!

I had mine installed with screws attached to the inside wheel well where the lip clips on to the left and right. In addition we used a glue in the middle to attach to the center bumper for more stability than just the 4 screws.

Overall, I wasn't happy with the lip in the end and found I could have saved money by just getting the replica M5 front for $350. Instead, I paid like 100 for the lip, another 140 or whatever for paint and install, etc.

Seems like everyone has the M5 bumper. I like that this looks different. There must be a way to make this thing stick on well! The product is from germany and the weather there is similar! I need some canadian feedback!! What spoiler do you have on now?
