Subaru WRX / STI Billet Mount Kit (w/ AG Lithium Battery)

Install was easy was just worried about the light battery starting the car but it works perfect. Thanks for making me the kit well worth the wait! Works with flex fuel kit.

I'm not sure where to begin with this review, but I'll start by saying that Valkyrie Engineering is one of the most professional, experienced, and customer-oriented companies I have ever had the pleasure of dealing with. Other companies could learn a thing or two from how they conduct business...

I ordered an Anti-Gravity Battery Billet Mount Kit for my 2011 GRB STI and found that the bracket I received was originally designed for a VA chassis STI which did not properly fit as intended. Naturally, I contacted Valkyrie Engineering and provided pictures; they worked with me over the course of a couple of weeks to take measurements and CNC a custom bracket just so that it would be a perfect fit.

When I say Valkyrie Engineering stands by their product... They stand by it. I have never had a company go to the extent they have to ensure customer satisfaction and I AM THOROUGHLY satisfied. Other companies would have likely told me to kick rocks and issue a refund instead of trying to rectify the issue.

So if you buy an Anti-Gravity Battery Billet Mount Kit for your GR chassis STI and flex on others about how Gucci and high-speed it is; just know the engineers at Valkyrie Engineering and I made that happen.

Deep thanks and gratitude to Shahab, Raphael, and the rest of the Valkyrie Engineering Team for putting out such a sick product and backing it with unfaltering customer service excellence!

I am writing this as a long test review because i wanted to make an honest long term review, because the folks at Valkyrie deserve it.
I have had this battery mount and battery for over 6 Months.
in this time it has been to 3 track days, the tail of the dragon for 2 trips and daily drove in the winter after being subjected to sub 15F temps when the car was covered in ice.
Never did any bolts come loose or did the battery move.
Car always cranked over without issue even in the 10 degree weather.
The finish is still fully black unlike some aluminum black finish that turns purple with heat, this has held up and stayed black.

The customer service with Valkyrie is second to none.
These are family people who eat and breathe motorsport.
"just like us"

Thank you Valkyrie, for making such a fine product.
