Tekno RC Rear Arm Mud Guards (2)

Yes for such a simple part it works well, and gives you a spot to add paint or stickers if you want.
I trimmed these to fit my MT410- the hole pattern is correct but needs about 5mm trimmed off the tapered wheel side.
Use polycarb scissors, these feel like a tad over standard body thickness.

I like that these are made from lexan. Every body I order I grab a new set of these guards and paint them to match the body. Looks great and I haven't had any failures or issues with them going on 5 sets now...

These make your ET48.3 look much cooler. I do not know how much it helps with the aerodynamics but it helps in terms of keeping your rear CVD's clean. I recommend them because it is not expensive and it can make your car look really cool
