Strengthening and Improving the Geometry of the S13 Subframe With GKTech and ZSM Custom

Now the mount was welded completely in place.

Pretty large gaps had to be filled so a lot of heat went into this part, a good reason for the good location that the bracket design provides.

The differential mounting point reinforcement came out beautifully.  You won’t be finding our diff on the ground!

Look at those nice tight welds!  This is great considering the gloppy stock welds on the cross member.

  1. 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.

    1. 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.

  2. 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.
