Zac skip-welded the reinforcement in place to prevent heat concentration and potential warping. This also reduces heat buildup and possible embrittlement of the welded area caused by welding.
You can see the electrode and the electrode cup that dispenses argon gas that acts like a shield to keep the oxygen in the air from oxidizing and weakening the weld.
Tig Welding has a nice smooth sound not all crackly like Mig welding, that is unless you are AC welding aluminum or something.
Next, it was time to weld in the front lower control arm pivot relocation kit. The first step was to cut off this part of the subframe flange that would interfere with the lower control arm bearing.
Here is the cut once it was done.

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.
