Easy installation. I pulled a 800lb HD 370 miles with no problems.


Awesome product. Fits as described. Great video on etrailer site. Robert was very helpful with getting me the right product.

2004 Mazda Miata

The hitch was simple to install - took me about an hour, fit great and you don't need a lift.

The instructions don't mention two things that you should be aware:
1st - get a tube of outdoor caulk to seal the bolt holes and keep water/rust away.
2nd - make sure to cut out the sound deadening material on the inside as needed so the brackets & bolts/washers touch metal. If not, the hitch WILL loosen over time.


OK for what it is--a hitch for cars not meant to tow. Installation wasn't too bad, but one of the heavy brackets was a bit misshapen, causing me to have to redrill a hole. Annoying. The hitch is VERY low to the ground, which may cause problems--I'm guessing any kind of extension/riser bar will decrease the meager weight limit even more. Most of the issues are car-related though, and not because of this particular product. All in all, it's certainly better than nothing.


Great productInstalled this hitch on my 01 325i coupe in under an hour. Directions are clear and easy to follow. Hardware appears to be quality. Once installed, the hitch is very sturdy. My only complaint is that it angles down under the bumper when if it was left straight it would still clear without a problem. This reduces ground clearance when a bike rack is installed, but I haven't had any issues so far. was great! The best price, free and lightning fast shipping. Thanks, guys!

  • Curt Class I Hitch, Part # 11178 for 2000 BMW 3 Series
    Both of the Class I hitches offered for your vehicle will attach to the trunk pan like the Curt Class I, part # 11178. As long as your trailer and its contents weigh less than 2000 lbs and the tongue weight of the trailer is less than 200 lbs, this hitch will work just fine for you. If you are unsure of the tongue weight of your trailer, I will include a link to our Towing FAQ page which will show how to determine your tongue weight.

  • Is the Hitch Pin Hole Depth Different Between Class I and Class II Hitches
    The hitch pin hole depth inside the hitch is different between Class I and Class II hitches. The manufacturers have done this to prevent Class II accessories, that are often heavier or can carry more, in Class I hitches to prevent them from being overloaded and damaging the hitch or vehicle. They weld a stop inside a Class I hitch so that Class II accessories with longer shanks cannot go all the way in.

  • Trailer Hitch Availability for 2003 BMW M3 Version Convertible for Use with Hitch Bike Rack
    We can help you choose a bike rack for use on your 2003 BMW M3 Version Convertible but I am sorry that none of our hitch manufacturers (Curt, Draw-Tite or Hidden Hitch) offer a hitch for your M version 3-Series BMW. Your option then is a trunk-mount rack. Recommended trunk-mount type racks for your M3 Convertible can be seen on the link provided. Both 2- and 3-bike capacity racks are offered. If your 2 bikes are not exceptionally heavy and you keep the vehicle's trunk surface clean you...

  • Trailer Hitch for a 2004 BMW 3-Series Convertible
    Since your 2004 BMW 3-series is a convertible the only hitch option for it is Curt Class I hitch # C11178. Hitch # C11174 is not a fit for convertible models. If you want to use the hitch for an accessory such as a bike rack or cargo carrier then you have to make sure the accessory is rated for use with a Class I trailer hitch. Also, with a bike rack, you are limited to 2 bikes maximum on a Class I hitch. Curt also says you have to use stabilization strap # 18050 when using this hitch...

  • Best Trailer Hitch Recommendation for a 2000 BMW 328i
    We do have trailer hitch that will fit your 2000 BMW 328i but # 24857 will not fit. If yours is a coupe, sedan, or wagon, excluding M series and convertibles, you can use # C11174.

  • Difference Between Curt Trailer Hitches C11174 & C11178 and Bike Rack Options for 2009 BMW 560i
    The visible difference between the Curt # C11178 and the Curt # C11174 is the design of that larger plate.

I do have a way for you to carry bikes with your 2009 BMW 650i Convertible but unfortunately neither of these hitches will fit and there are no other trailer hitch options available for...

  • Best Way to Carry 2 Electra Bikes on a 2004 BMW 325Ci Convertible to Avoid Scratches
    Thank you for the pictures of the bikes! It always helps to know exactly what the bikes look like that are being discussed. Although the Saris Bones 2 Bike Carrier # SA805BL is a cost-effective option that has received great reviews from our customers, if you are trying to stay away from solutions that could potentially put scratches on your 2004 BMW 325Ci convertible then I recommend going with a hitch mounted bike rack. Not that the Saris Bones (or any of our trunk mount bike racks)...
