gtspec front strut tower bar packaging The GTspec FSTB arrived well protected for shipping with a quality box. The strut bar was in a plastic package and all parts were neatly wrapped and wrapped again.

Infiniti G37 GTspec FSTB Build Quality: As can be seen in the picture to the left, this is no plain-jane strut brace off ebay. The build quality is excellent and there is attention to detail. The welds on the end of the bar show time was spent "doing it right". The brackets are strong and clean. The bar itself is quite light weight aluminum.

G37 strut bar installation Step 2. I started on the passenger side and ran into a slight snag. The G37 has three electrical lines running over the section where the Strut Tower Bracket is supposed to mount and they are tied to the car. Two of the lines (yellow arrows) can be freed up by loosening the panel they pass through at the battery. To do so, remove the battery cover; use your nail or a small screwdriver and pop the plugs out and remove (see red arrows in image to left). This will allow the panel to slide up somewhat and allow the bracket to be more easily inserted. Using the 12mm socket, extension, and ratchet, remove the three 12mm bolts (as shown in This Image) and set them to the side.

Take three of the supplied nuts and hand tighten them onto the bolts. The supplied nuts have a offset which is the size of the holes in the Strut Bar brackets so you will need to wiggle the bracket around to get all three nuts appropriately postitioned. Once they are hand tight, use the 17mm socket, extension, and ratchet to tighten the nuts back down.

Step 4. The drivers side allows for easy access so there are no panels to loosen. Remove the three 12mm bolts and install the bracket using the same steps as above

Lay the bar over the engine cover and attach to the brackets with the two bolts that were removed from the brackets before installation. The bolts should go in with the allen-head towards the front of the car for easy access. There should be a washer on the allen-head side and a washer + lock washer for the nut side. Insall bolts for both sides at this time.

In the case of the G37 Coupe, all the way up is too high while all the way down is too low. I found the optimal position to be appx 1/4 from the bottom which allowed hood clearance without having the bar laying on the engine cover. Use the crescent wrench, or wrench of your choosing, along with the 8mm Allen wrench to tighten the bolts. When doing the passenger side, I actually use a screwdriver to stop the bar from rising while tightening; you will understand when you start tightening the bar on that end.

Time and Difficulty. Total time for installing the bar was 30 minutes as I was being extra careful and taking pictures. This could be done in 15 minutes. On a scale of 1 to 5, the installation is simple and requires common hand tools so I would give this a 1.5 (easy).
