i had rogue spacers for my e46 m3. they were garbage. i had them on the rear of my car, since i run a square set up.
Regardless of the amount of anti-seize placed on the spacer, they would seize on the car. The other thing is that the lip would deform and would be a PITA to remove.
Also the smoothened angled edge would be very hard to pry off when I needed to remove the spacer.
All in all, I prefer the H&R by far. Maybe the new rogue ones are better. From their track record on so-so quality parts, I would stay clear from all their products - except their SSk - but thats an OEM BMW piece thats modified.
hahaha works of art. There was an exhibit of human feces on display at the Brooklyn Museum of Art. What constitutes art these days?
