i drilled holes and used 3m tape. the holes are supposedly the same pattern as the stock lip spoiler, i dont know that for sure b/c i did not have the oem lip spoiler b4. these guys inadvertently sent me 2 of the same spoiler, but about 4 weeks apart. some mixup over there. anyways, the first one cracked on the bottom (part touching the car) when i installed it. not a biggie, but the thing warped upwards a little at the edges, pulled away from the trunk lid left and right sides. i repaired the crack and left it installed. when the 2nd unit came, by mistake since i did not ask for a replacement due to crack being my fault, i called racing solution and they did nt want it back. so i gave it to my buddy. i don;t know if he installed it or not..... anyways, thanks for the props CSOCSO.

 

well.. tha warping thing is really bad but i love the look so im gonna get it..

 

it didnt warp much, maybuy 2 mil from the body. if you had more tape that might be adivsable. i would suggest you use the bolts too tho. i put the bolts in the uninstalled spoiler then pushed it dwon on my hatch to "mark" where to drill. then i grabbed the smalled bit i could find and drilled 2 pilot holes, checked the location and holes matching up to bolt holes in spoiler and enlarged them from there. grab some silicone pvc caulk to seal up your work so you dont get water in you trunk. i know everyone knows this, but my silicone was already opended and all dried up, thus delaying my work.....

good luck!
