Rexpeed vortex generator VG Non SSS - Review & Install
Review: Rexpeed vortex generator (VG) for non SSS
material of vg - stiff fiberglass
price - 10/10, $165 painted WW
instructions - none
tools provided - 3M tape
tools used - 3M double side tape + drill + sandpaper + textbooks + barbell weights
people to install - 2
pre-color match from rexpeed - 9/10 (close enough)
fitment -
initial fitment is 5/10 from the box w/out personal modifications. only the antenna base hole was in the proper center location. But the size of the antenna base hole wasn't up to par. The tail end of the vg didn't reach the end of the roof. Also, only one side would lay flat or align during test fitting.
personal modification had to be done.
Shaved off 1/4" from the head of the antenna base hole (& its upper curved corners) so that the tail end of the vg can align & wrap around the end of the roof that meets the rear windshield.
To shave off fiberglass: I marked off how much was needed to be shaved (started w/ 1/8"). I then used a drill and used the side edges of the drill bit to shave off fiberglass. Moved drill slowly from side to side. Shaved off fiberglass in small increments. Test fitting after each shaving. Once the appropriate amount was shaved off and the tail end of the vg fit around the end of the roof; fitment was much improved. Used sandpaper to smooth out rough shaved areas.
The sides also laid flatter and were more aligned. At this point, fitment was 7.5/10 w/out tape.
Tape areas:
Mounting: After shaving excess fiberglass & test fitting. Time to get that buddy of yours to help align & then hold down the opposite end as you apply the taped vg onto your roof.
total install time: a whopping 8+hrs total. Yes. After install, you need to put weights (i used old textbooks, 5lb & 2.5lb barbell weights) on top of the vg so it can:
-stay in place
-help 'shape' the fiberglass to the curve of the roof
-help w/ tape adhesion.
Lay out a cloth on top of vg to serve as a protective layer before stacking your weights. Place weights in areas where you see fit. Leave the weights on overnight.
Results: (raw pix, car unwashed), fitment isn't perfect, but close enough & a vast improvement from 'out of the box'. - FINAL FITMENT RATING 9/10
Recommend to others:
Sure, but consider...
pros:
-price
-material
-color matching
cons:
-fitment
-possibility of extra labor, but certainly manageable.
Thanks for taking the time to read & hopefully my experience w/ the extra labor during installation is an isolated case.

Was really thinking about getting a rexspeed cf one for my car. Even though I have the SSS package i bet i run into the same problem. To much time and effort for me but like you stated the pros and cons so its all personal preference and budget. Thanks for the review there isnt but only one other i believe or a video of how to install it.

Only1Balto -- good question. i hear ya, but it's not a major concern if you are diligent w/ the cleanliness of your car.
personally, living in a dry climate, it's not a big concern. when i wash the car, i do it myself and cover that very small area to prevent water entrapment.
on a rainy day, the cut out may entrap/collect a very small amount of water and catch a bit of dirt. that's a possibility for sure; but it surely wont be significant enough to 'ruin' paint.

tl;dr- don't worry about it too much, water drains out the windshield water channel...in theory.

pro tip: peel pack only 1" of the tape back on each side of VG
set VG on roof, align perfectly, then press on each side. After each side is tacked on, slowly peel the rest of the tape backing out from under the tacked on VG. That way it stays in place as the tape attaches
white on white looks outstanding, I wanted a white X but htey didn't have any :/
