Question: How about vibration/shaking while driving. I had the big mirror and it was so blurry you could hardly use it.
Document: My husband added these to my cart that I use for getting around in our gated community. Had a rear view mirror but that didn't cover enough area. With these mirrors, I have plenty of warning when a car is approaching from the rear and I can easily move over the let them pass. LOVE THEM!!!!!!!! !
I finally got the side rear view mirrors for my EZGO TXT after some shipping problems. RockwallGolfCarts resolved the problem to my satisfaction and I'm a happy camper. The installation is easy and minimal drilling. They use sheet metal screws that seem fine for now... We'll see after some vibration... May replace with small bolts through the roof frame.
15 minutes per side max.............. done and done. Adjustable tension on each mirror to accommodate for road vibration. Great for the Club Car.
I bought these mirrors for my EZGO Express L6. They are a bit smaller than I expected, but that was my own mistake. I guess I didn't really think about how big of a mirror one needed for a golf cart. These are just the right size. The plastic mirror housings are just a touch lighter and thinner than you'd expect however.The real problem came during the install. The instructions say to drill at 1/8&#34; hole in the riser for the screws.
mirrows were better than expected. I mounted with bolts and nuts. no vibration and excellent quality  I would highly recommend these
I got these for my daughter's golf cart as she is a beginner driver. She can see reallly good out of these big mirrors, and they easily fold in for tight places.
Secured easily to our golf cart. Very sturdy. Collapse for tight parking. I feel much safer. Great for on the road use.
These are good quality mirrors that are easy to install. They don't vibrate like the strip mirror I used to have
I have a club car with a fold down windshield. These mirrors did not fit on the frame until I cut the lower corners off the upper half of the windshield. Its kind of sloppy looking but they work. I would not buy this mirror if you have a club car with windshield.
I have a Club Car and had damaged one of the mirrors, so I replaced both of the mirrors with these. These are so much better than the original Club Car mirrors. They are larger and more adjustable. Plus you can turn them completely in to prevent them from being hit (which is how I damaged my original mirror).
Answer: yes
