Gofast, the fenders definitely help for clearancce on the trails. I don't rub at all in the front even with the 35's.
JayR, the fenders do't come with welss, but i cut the stock ones so they are just protecting the engine compartment from getting big splashes up in there.
In the above picture it is rubicon. That was the first obsticle about 1/2 mile into the trail. My front tire did not rub at all in that picture.
