I bought them:
Given that the Ikon Motorsports louvers are about a 1/4 to 1/3 the price of the TRD louvers, some of the parts are cheaply made:
The brackets (
https://www.amazon.com/Double-Adhesi...ble+sided+tape) are small rectangles with a double sided tape holding it down - some of them came warped or bent. There are threaded posts sticking up from the brackets which are first threaded (sometimes very poorly) and painted black.
The supplied hardware - washers and acorn nuts - aren't exactly useful. The washers eventually rust after a week or so - even quicker after it's rained. The acorn nuts are nylon and don't exactly fit the threaded posts or eventually come loose.
The weather sealing strip that is provided works if everything else is perfect - which it isn't. It's very thin and only two rolls are provided - enough for about half of the louvers - to prevent vibration.
Having to buy the thicker weather stripping to eliminate all vibration at highway speeds and stainless washer and acorn nuts, isn't too bad.
The real flaw of these louvers is the brackets!
I'll need to find someone to make me some better brackets - ones that will cover a broader area. One large bracket across the top, one on each side, and one across the bottom would do it, instead of nine separate brackets.
