The Spoiler is of very good Quality. Requires sanding and proper prep for raw plastics... did drill some holes in the bottom to get some loose materials (resin) out... Material Sands very well with a DA sander.

It seams to be a variation of the gm. Z-L1 spoiler. Which is my favorite of the 5th gen spoilers... Once I seen they used the existing holes used for the factory spoiler... I was on board for one immediately. Install is so easy!
Fits like ITS FACTORY! Thank you for this spoiler.
Only reason for 4 stars is my foam washers were missing in the delivery of the spoiler. Props to Phastek for sending out replacements and calling me to let me know they were on their way.
