I installed skid plate on my WRX wagon. Very satisfied.
Plate fits perfectly, I used bolts from stock skid plate, had to find some bolts to screw plate at the back, they wasn’t supplied with plate I used big washers, because holes in the plate pretty big.
I am not sure if its a quality of aluminum, but its seems to me its too soft, and bolts even with washers trying to sink into hole.
Whole installation took me about 20 min.
No vibration, very good quality product.
But I have a question: would drain valve fit under the plate?
