ERKUL Lockable Aluminum Roof Rack Cross Bars for Mazda 3 (2010-2022) | Universal Cargo Carrier for Kayak, Canoe, Snowboard, Bike & Luggage | Heavy-Duty Black Rooftop Bars | Perfect for Road Trips, Camping & Outdoor Adventures

I bought these for my 2010 Mazda 3 i-Touring sedan. It was a pretty straightforward installation. The direction booklet is a little off (doesn't reflect all of the pieces that come with it and they don't match the photos), but everything you need is there. You will need to remove your weather stripping window seals.At first, I thought the M6 screws and matching male-female coupling/standoff nuts did not fit with my car (the fit was tight at first and I didn't want to strip the thread by forcing it); however, I used a socket wrench which provided enough torque and it fits perfectly.Couple of notes, make sure the locks are set in the unlocked position putting the plastic cover on; otherwise, it won't go on and will break the plastic. Driving around with just the rack on, I do notice wind noise starting at 50mph but it's pretty quiet.It feels sturdy and I haven't loaded it up yet, but I'll report back once I actually put the luggage carrier on etc.I bought this for my 2013 mazda 3 I sport sedan. It was relatively easy to install and only took about an hour. There are a few things that will make installation easier. I initially had a hard time getting the ends on the crossbars but I ended up loosening the screw and pushing the back plate a little, which allowed the bar to slide in easier. Make are you tighten the screw once you get the bar in. There were also extra pieces with no instructions on what they were for. I figured out that they screw in to the mounting points on my car so the screws could go into them. Otherwise the screws were a little too short. Overall, it was easy enough to install and it's sturdy so it beats paying $300+ for a different set of crossbars.Got it for a 2019 Mazda 3 sedan. Had to go to about 1 inch each side on the rails. Back feels more sturdy then front rail. Only thing I need to do is buy 2 more washers for the front rail to make it more snug. Haven't used them yetReasonable price and easy install and used the extension.This was supposed to fit my Mazda3 but didn't. Unfortunately I didn't realize until after I had already drilled holes in the top trim. Completely disappointed. I would be very reticent to buy from this company againLove this product but had a hard time getting the screw to the car. Wonderful after finding out there’s extendors!
