Some of the reinforcing pieces used the OEM bolts and the control arms bearings to hold them in place during welding for proper location and to reduce the chances of warping. Zak is bolting a reinforcement in place here before tack welding.
Now Zac tack welds the reinforcement in place to get it located before seam welding it in place.
Here are the tack welds. If something is out of position, the welds can be easily ground off and the part repositioned. This is the rear lower control arm mount gusset. As you can see this part makes the pick-up point many times stronger.
Zac then tack welds the upper control arm gusset in place. This is a nice dimple die part that looks cool.

Thats some awesome attention to detail. I can only see myself crashing the car on its maiden voyage with all these nice parts. Love the photo documentation as well.
You guys always do it right. Kinda of rare. If I ever need or one of my friends needed some work done or just good advice I would reccommed your outfit 100% Mike. Thanks.
i’ve installed quite a few of the s13 and s14 gktech weld in reinforcement kits (haven’t done the s13 roll center correction one yet) and i HIGHLY recommend this for ALL 240 owners. if you’re dropping the subframe to install solid bushings, its a great time to have the whole thing sandblasted and the gktech kit welded in.
Personally, i mig weld them, but if someone wanted to pay for the additional time to tig weld (most of the time is spent getting super tight fitment for all parts prior to welding) i don’t see any downside to it in this application.
Actually, it reduces anti-squat but it does move the roll center a little lower as well.
