Save some weight switching to a group 51 battery (Honda Civic sized). The group 51 battery is a great choice for a street car as it still has the capacity of a fullsize battery, but can save about 20 lbs over the stock sized battery. This hold down is designed to securely grip the smaller sized battery using the stock hold down j-bolt and strut tower mount stud. 5 minute install!
Add some bling, save weight, and 5 minute install?! It also saves some space underhood without needing to relocate the battery. Basically a no compromise battery setup.
Please keep in mind there are variations in battery dimensions. This is shown with an Optima battery and it should cover almost any in specification Group 51 battery, but it may be slightly wider than some batteries. This doesn’t really hurt provided the battery is tight enough it doesn’t move. If you have trouble with it sliding you may consider putting some double sided tape on the bottom or other material to make the stock battery tray not so slippery.
