Still holding up as well as the day it was installed (Mar'20). I've loaded this system down with a basket full of camping gear and another trip with 3 kayaks and single bike. Everything stayed solid and didn't budge at highway speeds and windy mountain roads.

  • Custom Fit Low Profile Roof Rack System For A 2016 BMW X5
    I have the perfect roof rack for your 2016 BMW X5 that matches all the requirements you have specified. For a roof rack with aero crossbars and no overhang, you will want the Inno Aero Crossbars part # INXB108-2, part # INXS400, and part # INTR140. The Inno Aero Roof Rack System is a direct fit for your vehicle and the cross bars that mount to the vehicle's side rails are placed into the end caps on the foot pack included with this kit. This will in turn position the crossbar ends directly...

  • Recommended Roof Rack for 2016 Lexus NX 200T with Flush Mounted Rails
    We do offer a wide array of roof racks that are confirmed to fit the 2016 Lexus 200T vehicles. The only model I could find that has the flush mounted rails like you mentioned in your question is the NX 200T. If this is your model Lexus, the most cost-efficient crossbars and fit kit we currently have available is the Inno Aero Bar Roof Rack, which consists of parts # INXB93-100 for the two aero crossbars (front crossbar is 36 inches and rear cross bar is 39 inches), # INXS400 for the Flush...

  • What Flush Crossbar System do You Recommend for My 2022 Mercedes GLC SUV with Flush Rails?
    From my available specs on your 2022 Mercedes GLC SUV, you have flush mounted factory rails on your roof. For a great flush roof rack system of crossbars that don't extend past the roof rails, there is one that fits your vehicle style. For that route, I recommend the following setup: - Inno Aero Crossbars - Aluminum - Black - 36" Long and 39" Long # INXB93-100 - Inno Flush Feet for Aero Crossbars - Flush Side Rails # INXS400 - Custom Fit Kit for Inno XS300, XS350, XS400, XS450, INTR,...

  • Is The Sportsrack J-Style Kayak Carrier SR5511 Compatible With 2010 Santa Fe Roof Rack?
    The SportRack Kayak Carrier with Tie-Downs - J-Style # SR5511 will fit your 2010 Hyundai Santa Fe if it has the factory crossbars running left to right across your roof. If your vehicle just has the factory side rails running front to back then you will first need to install a crossbar setup such as Inno Aero Crossbars # INXB100-108 with the necessary Feet # INXS400 and Fit Kit # INTR166. I attached a couple demonstration videos for you.

  • Available Inno Roof Rack Fits for 2018 Honda HR-V with Flush Roof Rails
    We offer three roof rack systems from Inno that fit the 2018 Honda HR-V with flush mount roof rails. Please note that none of these are square bar racks; all use Inno's Aero crossbars, which for your vehicle are available in three bar lengths. You can see all of these on the linked page. With these racks you have a choice of a flush fit for the Aero crossbars with the rack feet or to have longer bars that extend out past the rack feet. The flush system uses 39-inch bars and consists of...

  • What Crossbar System do You Recommend that Doesnt Extend Past the Feet on My 2018 BMW X1?
    I have a great flush crossbar system for you. Unfortunately, I confirmed with Thule that they discontinued the Fit Kit 4023 which is required to mount the AeroBlades TH7602B-TH7603B to your 2018 BMW X1. Without that fit kit, there is no way to attach the AeroBlades to your flush rails. We also do not have any other Thule systems that do not extend past the feet that fit your flush rails. With that being said, the only other option for a crossbar system for your X1 that does not extend...

  • Will Inno Square Bar Roof Rack Fit A 2018 Mercedes GLA45 AMG
    Yes, the Inno Square Crossbar Kit including parts # INB117, # INXP, and # INTR162 are a confirmed fit for your 2018 Mercedes GLA45 AMG. We can't recommend using duct tape between the mounting feet and your factory rails. The rack was designed to fit to the factory flush mounted rails so an additional material between the two could affect it's hold and reliability. These feet are designed to fit without scratch or damage so you can feel good about this solution. I have also included...

  • Thule Flush Roof Rack For a 2017 Lexus RX350 with Factory Flush Rails
    I do have Thule options for a 2017 Lexus RX 350 with flush rails but the Thule AeroBlade Edge is an old system that we no longer carry the correct fit kits for. Instead, I recommend the Thule WingBar Evo Crossbar part # TH711220, part # TH710601,and part # TH186044 which has the updated design. I know this system doesn't have the flush bar style you were after but they don' stick out much further at all and they allow for more items to be carrier. It can also be easier removed when not...

  • Will A Roof Rack On My 2019 BMW X3 Interfere With My Sunroof Operation
    Any aftermarket roof rack you purchase for your 2019 BMW X3 with flush rails may have issues with interference between the roof rack and the sunroof. In fact, this interference is mentioned in all roof rack instruction manuals. My recommendation for customers who want to know if there will be interference is to put your front crossbar and tower/feet/legs together and place it on the roof in the correct position. Do not install it, just put it in place on the roof. Then CAREFULLY open your...

  • Will the Malone DownLoader Fit Inno Aero Crossbars on My 2020 Mercedes GLA 250?
    All of the crossbar sizes of the Inno Aero crossbars that we have listed as confirm fits for your 2020 Mercedes-Benz GLA 250 are the available size options that Inno has for you based on your crossbar length needs for the vehicle. Depending on what accessories/cargo you need to transport, you can use more or less crossbar space. The length does determine how long the crossbars stick out past the feet. If you are planning on transporting a kayak, I recommend the longer roof rack bar system...

  • Roof Rack Recommendation for a 2015 Audi Q7
    It looks like the 184002 fit kit from Thule has been discontinued so while the Thule AeroBlade Edge # TH7602-TH7602 is still a valid part, this means that we will need to go a different direction for your 2015 Audi Q7. I recommend going with the Thule WingBar system because it is the upgrade to the AeroBlade Edge, but if you're more concerned about a roof rack that has crossbars that end in the legs then you'll need to go with the Inno roof rack instead. I will list both options below...

  • Flush Mounted Roof Rack for 2018 Audi Q5
    Roof racks are custom fits for vehicles, and the Thule rack you mentioned is an entire kit and won't fit on your 2018 Audi Q5, although there is a rack with the same style which does. So long as you have flush-mounted rails there is a rack from Inno which has crossbars match the width of your Audi's roof: - Inno Aero Crossbars # INXB100-108 - Inno Flush Feet for Aero Crossbars - Flush Side Rails # INXS400 - Custom Fit Kit for Inno # INTR138 For a Thule roof rack, they have a style where...
