The GKTECH S13 anti-squat reduction weld in kit has been designed for those with an S13 (or R32) rear subframe that want an increase in rear-end grip. Designed from a 3D scan with the addition of CMM data the brackets relocate the front pick up point for your rear lower control arm altering your suspension curves.
Laser-cut, steel, and with simple step by step instructions makes modifying your subframe a heap easier than attempting to do it yourself without guidance.
S13/R32 rear subframes have a higher anti-squat value of 45%, changing the pitch of the rear lower control arm by relocating the front pick up near 2 inches lower you are replicating the geometry of an S14/S15 and changing the anti-squat value to 0%.
This gives further traction through corner exit, bumps etc by allowing the car to squat (and actually use the suspension as intended). This is a common modification for anyone looking to get more forward bite on their S13 and we’ve now made it easier than ever.
In addition to reducing the anti-squat value, roll center is raised 20mm increasing roll stiffness, anti-lift is reduced from 80% to 20% assisting in braking by reducing wheel travel and preventing droop when hard braking.
Bump steer is also reduced by 6mm at 100mm compression/rebound. In short, this is a MUST for S13/R32 owners looking for more traction.
NOTE: due to the increase in misalignment in the rear LCA bushes, using aftermarket LCA's that run spherical bearings/heims or spherical bearing conversion for your OEM rear LCA is recommended as sold here: S/R Chassis OEM rear LCA spherical bearing upgrade (set of 4)

FAQs
Will these fit my car?We can only confirm fitment of the vehicles listed above. If your vehicle isn't listed there then we can't be sure. Sorry
How hard is this kit to install?
It is pretty straightforward and the subframe doesn't need to be removed for these to be fitted but you'll obviously need access to a welder and know how to use one. Gluing these in wouldn't be anywhere near as effective
Are these FD Legal?
Yes, based on the following from 2020 FD Technical Rules and Regulations Additional mounting tabs may be added to the subframe to relocate the suspension arm mounting points within a maximum of 2 inches on any plane from the original mounting position.

Guys, received my order today .
I am blown away at the quality and fabrication of everything.
Went for the Grip option on my Nissan S14 as I have lost my faith in my drifting abilities-67years old !
Cannot wait to assemble everything . Extremely happy I went with GK Tech !
The inner arm relocation bracket is of excellent quality; it is a bit complex to install, but the mere fact that you don't need to swap the subframe to get improved traction—like on the S14 or S15—makes the effort well worth it.
Welded them in with subframe still in car, no issues
Easy mod well worth the short time to install perfect upgrade for r32
Absolutely outstanding results from a few hours in the shed.
GKTech knock it out of the park again
The first set I bought the right one was bent up and not useable so I had to bought a second set and they are perfect.
Hi Kyle, sorry to hear of the trouble. Possibly the first one was bent in transit. Feel free to reach out to us and we'll get you sorted.
These welded in easily, and had pretty good fitment. Have not drove the car with them yet. One thing that would make it easier to install is to have them come in a raw finish like all of the reinforcement plates. The paint is tough and is hard to strip off the inside during welding prep.
Great part, good online instructions and fast delivery like always.
Excellent, very prompt and quick delieveries

Really glad how innovative gk tech is in the s chassis community
Excited to run these
Good quality, easy installation and save me from swapping parts from another chassis....very happy
Was very happy with the product it saved me making one from scratch
GOOD PRODUCTS AND SERVICE AS WELL
This is a company that not only makes excellent parts,their service, and back up is second to none.
Easy to install and great way to finally get grip in your s13. 11/10
I found the installation video and hard copy instructions very helpful. Made the installation of this weld in kit very easy.
Cannot wait to drive the difference this anti squat modification should make.
Very innovative simple upgrade.

Gktech are doing a Stella effort with what is coming out with and these are a great idea as i really couldn't be bothered putting the s14 cradle into my 180 as i didn't need the extra track that it gives you. Keep up the top effort and Zac is a top bloke to deal with 😊
Goes with your build
Picked just for you 😘
