My RPI Designs ZR1 Rear Spoiler Review
Thanks to Josh at RPI designs for a great product, speedy delivery, and quick response to all questions.
I took advantage of their Holiday Special and ordered on the 9th. Package arrived today, the 29th. 15 business days! That is quick for a piece that needed to be painted.
The spoiler was packed with the utmost of care; boards were taped to the spoiler itself which was then wrapped in foam sheeting. The box was stuffed with paper and even had pieces of Masonite taped to it for protection.
And speaking of painting; the color is spot on perfect! And they say silver is hard to match. Not this time.
On attachment: I had intended to try and attach the spoiler with 3M tape. After looking at the construction, this will be impossible (without modification). The stem brackets that bolt the spoiler to the car are too far away and do not come in direct contact with the car body for tape contact. Ain’t gonna happen!
Whoever attached this thing with tape please step up and tell us how you did it.
More on the attachment once I install this beautiful accessory!
My only concern is the brake light hole. I am full confident that once the light is installed and the spoiler attached all will be well. However, we will have to wait and see how it goes.
Thanks again RPI Designs for a wonderful product at a reasonable price. Happy New Year!

I mirror your thoughts exactly. I too wanted to use tape but ended up bolting mine on. Don't worry the brake light hole will be fine once the light is in there. Post pics once it's on.

I have had the same spoiler installed for way over a year and here are my tips for installation. Lay out the template they send you per the instructions. Take some old lipstick and rub it on the ends of the bolts on the spoiler. Get someone to help you and position it as best you can on top of the template. The lipstick will leave marks on the template that in my case did NOT line up with the template hole marks. I drilled on the lipstick marks and used a bit slightly larger than the one specified. Test fit your new spoiler and see if you like the position. The reason I used a slightly larger bit was as I tightened down the nuts the spoiler wanted to torque a bit. The slightly larger holes allowed the unit to move a bit and let me make minute adjustments as I tightened. Get yourself a small, ratcheting box end wrench to tighten the nuts. (10mm if the brain remembers) Good luck!!

I just got mine from Josh today but no template Will contact Josh. That being said however I didn't want to drill my rear spoiler either. I was contemplating filling the spoiler with an expanding foam, allowing it to fill a small lip around the spoiler on the inside. I would then shave off the excess around the spoiler so that it is flush when installed on the bumper and then utilize a 2 sided tape to adhere the spoiler on the ends. I am going to see what tapes are available via my bodyshops and then start to verify how feasable this might be. If I proceed I will take pics and post in case it is of any use to anyone.

Make sure you drill the holes 1/8" larger diameter than needed, this will allow the spoiler move enough to sit flat. If properly installed these will sit very flat. I have one on my 2010 Grand Sport.

I ordered my ZR1 spoiler from Josh last year. The paint match was perfect. I did not use a template. (It is basically a waste of time). I masked off the area first.
Remove the high mounted brake light from the OEM spoiler and install it into the new ZR1 spoiler. Then, I used the lipstick method. Use the 4 OEM holes in the middle to align everything and a dab of lipstick on the ends of the new studs will leave clearly visable marks on the car. The tail cap is soft urethane plastic, so I used a cordless drill to drill the new holes. You will need a Torx screwdriver to remove the taillights in order to access the nuts that go on the underside of the studs. Do not tighten too much as these are fragile parts. Remember to reconnect the high mounted brake light wire before you reinstall the tail lights.
I debated using double sticky tape. The problem is the spoiler moves around on the car and it will rub the paint and leave marks anyway, so there is no way to just reinstall the OEM spoiler. The installation is permanant and I wanted the new spoiler to fit flat on the tailcap with the proper alignment with the rear lip. The best way to do this is to bolt it on as the nuts will pull the spoiler down into place.
The entire installation can be done in less than 30 min.

I had no problem installing mine until I had to lift the back and push down on that skinny bowed out piece under the third light.The piece cracked and broke right in the middle .I sanded the two pieces,added some silicone caulking and ran a piece of color matching pinstripping under the third light to cover the crack.Don was very pleasant to deal with offering a discount on my next order.Unfortunately,the discount is not substantial enough considering I have a cracked zr1 spoiler bolted on my vette.

Sorry to bring up such an old thread...
So, was the crack due to how you installed it or would you consider it a weak point in the design?
To others, how has this product held up? I'm looking to add a ZR1 spoiler to my GS but I'm debating this vs. OEM. Thanks!

I have had a RPI spoiler in the color silver for a couple of years. Color match was good, fit was good. I had a body shop put my spoiler on, tho.
