I've been looking at getting one of these for awhile, and had not really seen many reviews of this heatshield panel...So here's my take on it. I purchased the 2006+ Civic R18 Heatshield Panel (which I am told also fits the 2012+ civic R18 as well)..

I called S2carbonworks to see if they had some in stock, they did, when I got there they offered to install it for free, and even hooked me up with some dressup fender washers and some stickers.
Anyways, the panel has very good fitment, looks great and they guys there were very helpful.
Initially I had heard mixed reviews of that place, but you know how the internet is sometimes you can't believe everything you read...Overall I had a good experience and the product is awesome. Hopefully they can make some more goodies for the civic in the future.

I just picked up my 06 civic, so I hope to do some more mods in the future, tein springs, work wheels, hfp lip kit, and the red JDM h badges.

 

Thanks for the positive feedback.

Post some pics when you get a chance.

 

Although I do not have this product, I can vouch that it does indeed fit the 2012+ R18.
