A little overpriced
These fit well and adhered nicely. A little pricey for a bunch of foam.

Why didn’t I do this the first time?
I can’t believe I ever did an install without these. Amazing improvement in sound quality for a low price.

Recommend!
Helps transfer sound from a speaker mounted behind door panels by sealing the gap between speaker & door panel. Really helps the increase midbass output & overall sound.

Great product
Used these for a Toyota Sienna with Morel Maximo Components. Easy to install, did not install the large back piece on the door to avoid water absorption but used the inside and outside rings.

Makes the system sound so much better
I didn't know nor heard of FAST rings until a friend of mine Jim taught me about them. A must have

Roadkill 6" and 6.5" FAST Rings (RKFR6)
This was my first time buying and using the roadkill fast rings and I can honestly say it made a huge difference in quality and loudness. I will continue using this product for all my future installs well worth it and great price.

They do work
All I can say is these things work as advertised. They aim the sound and cancel back waves. Thus increasing mid bass. This along with sound deadener in your doors will make a noticable difference. The only draw back is they are not waterproof.
