Anybody know of a rear trunk spoiler that is bolt on. Do like the looks of the DAR spoilers but want a install more like oem.

I know a lot trust the 3m tape install but I don't. It is great stuff and works well most of the time. But I will be keeping my 2011 LS for a number of years and don't want to worry about it. I have seen a number of things like vent visors last a few years with 3m tape and no problems. But not all, but most I have seen start to come loose after about 4 years.

Just don't want the liability if it was to come off on the interstate and cause a wreck. Just with a local paint shop and also the lexus dealers paint shop and neither would recommend one that installs with just 3m tape.

Really like the spoilers but not enough to hassle with keeping an eye on it and redoing the 3m tape. Want to keep the same quality as what lexus would do with the install themselves.

Thanks

If it is a lip spoiler made of urethane it will be mounted by the use of red 3M tape. The surface needs to be extremely clean and should not have any wax on it so it requires you to use a clay bar on the area before attachment. Most lip spoilers as well as other body panels come with red 3M tape and the longer it's on the car the stronger the bond will be. If you want to speed up the process you can use blow dryer. After a good attachment has been made you will need a knife to remove it.

I understand your concerns and skepticism, but first hand experience tells me it is very difficult to remove once applied. It took me and a buddy 20 mins to remove a spoiler stuck on the trunk when he was trading the car in. We had to use a knife, credit card, and lots of finger strength to pry that thing off.

In all my years using 3M red outdoor tape, I have never had a problem. But then again, I always ensure the area is completely clear of wax using alcohol and completely dry. Then when applying the 3M tape, one way to ensure bonding is heating up the metal with hair dryer and then apply the 3M. Then once spoiler is installed, use some more heat from the blow dryer so that it's hot to the touch. Then lay down a sheet or blanket on top of wing and place some small boards on top of the sheet along the length of the spoiler and then added several bricks to create pressure points forcing it down on the trunk lid. This worked on my roof spoiler and the biggest testament was a lip spoiler I installed on my old Acura back in 2006. 8 years later and being in cold and hot climates, that spoiler hasn't moved or nor have any gaps appeared. I really believe heat and pressure ensure a strong bond with 3M red outdoor tape

CJITTY, great info here.
Also, if you don't need to have the option to remove a trunk spoiler later, you could also use silicone adhesive(black) by itself or in conjunction with 3M tape. Use the 3M tape on the outer sections and put the silicone inside...keeps the silicone from squeezing out from the edges.
I would recommend only using 3M tape on a roof spoiler though.

That is part of the installation that DAR spoilers recommend. They seem to be the most popular one. But they do not recommend 3m tape by itself They do recommend the silicone adhesive with the 3m tape.


I am still not clear on if any car brand has a oem spoiler that is not bolt on.

The large DAR spoiler has threaded holes you can use to mount the spoiler in addition to the 3 tape.

Did you see this on one? When I called DAR they said it was 3m tape only.

Thanks

Just keep in mind that when you drill holes in the trunk you will open yourself to rust as well as galvanic corrosion. You will see this with idiot car install people who tap for ground wires on the body.

Did call DAR again. They do offer to install bolt holes (but you have to ask) so you can install either way. Seems to be a good company to work with.
Also you get a Club Lexus discount if you buy direct from them.
