Quick warning about GKtech
 

So I purchased their FUCA's. Seemed like a good deal. Caster adjustment, on-car camber adjustment. Much cheaper than SPL. Solid joints.

When they arrived one set was visibly narrower than the other. Quite difficult to fit onto the car as well. Their response? Must be a problem with my eyes.

Now I just got around to installing their rear camber arms. Pictures below. Their response? I must have installed them incorrectly.

You bought that cheap junk. Guess you will have to deal with it.

Ouch! Lesson learned.

Sorry you got to deal with this. I'd reccomended fighting it cause that is some bs and get your money back. For future, theres a reason why everyone here recommends SPL or at least SPC.

Yeah lesson learned there :ugh2:

If you used your credit card or PayPal, get them involved.

I'm ordering SPL right now and all this junk is going back to the store.

I have a set of their arms and had no issues. Sorry it didn't work out for you

Edit: it looks like you still have the eccentric bolts with the rear lower control arms. You will also need to get a lock out kit which replaces the inner bolts.

When you uninstall them, it’ll be good to take more detailed pictures showing the differences, especially the FUCA.

I have a set of digital calipers on order for exactly this purpose.

Amazing that folks STILL dont just get SPL and sleep well at night knowing their **** will fit, wont break, and adjusts easily and securely

No pity here

That's a damn shame. I've been following them because their designs looked to all have good adjustments and for half the price of SPL. Good options for someone trying to overhaul suspension on a budget.

Sometimes you just take one for the team.

I'm following for photos and measurements when uninstalled as well -- it'll be easier to withhold any judgement in case of incorrect install. I have purchased other GKtech components (shifter + knob, diff brace) that I'm very happy with thus far, and I intend to eventually mimic Brendan's FUCA setup for autocross. "Only SPL" isn't a healthy solution and GK's is definitely a more promising option than Z1 (which I'm currently using) or SPC.

Op forgot about this thread like my dad forgot to come home after buying cigarettes.

No, still pending. SPL gear arrived just recently after getting stuck in customs. FUCA's are now swapped out. Just need to do rear camber arms before the car goes into the shop for 1-2 months.

I have a GK Tech diff brace and diff bushing puller and was very pleased with both. Fitment and function of the diff brace is spot on and the bushing puller worked like a champ. Maybe stay away from their suspension components? I am running SPL for camber arms and those things are awesome. Voodoo13 stuff seems to be just as top notch as SPL just from photos, though.

Do you have pictures of them uninstalled and visibly shorter? In the picture now its hard to tell if it is actually shorter or if it was maybe it was installed wrong like others were suggesting?

I have them off the car now and will update with a full review this weekend. There is no doubt that one side is shorter. By a significant margin as well (over an inch).

Also will update with their FUCA's which have similar quality control issues.

Finally got some time to take some pictures of the arms. I put the left and right rear camber arms next to each other. Some serious quality control issues there.

Then I took a measurement of the FUCA's. There is a 2.7mm difference. It doesn't sound like much but it means you WILL require a pry bar to install them. They also clunked like crazy, even over the smallest bump. Some nicks in the metal makes me think they are hitting the car body.

I replaced all of them with SPL billet gear and when opening the boxes I was immediately hit with a serious flaw with the SPL arms. They are too nice to install under your car. Inside your car? Yes. In your engine bay? Maybe. But not under the car where they will get all dirty. They are seriously a work of art and now I am going to have to get under there to clean them after every drive :ugh2:

Nothing to argue on the rear camber arms. It is pretty damning. Mismatching arms being pkged together. Wow.

That's a serous clusterfuck. :shakes head:

Tip. Before you install the SPL parts. Take everything apart and coat all the threads with ant seize. Years from now. You will be able to still be able to do adjustment.

That is insane, in the rear quality control was not in that day:eek:

On the front.... well I can see why they would try and fight you since it's not so much but still. These are suspension parts, the least you could do is make them even. Hope you get this figured out.

That is so far off that it looks like they gave you one correct arm and then another for a different car.

You think the regular SPL stuff is too pretty?

Check out the "Nismo" branded version (same stuff made by SPL, just diff colors):

This GK horror story reminds me of my experience with Serial-Nine on my IS300. They made two versions of their FUCA, one for VIP cars on bags with extreme camber and a "sport" version for closer to stock suspension. I got the "sport" version but it maxed out at STOCK camber (near zero). Switched to the VIP version, and could only get MINIMUM -7 camber. It was baffling.

Only when I lined up VIP, sport, and stock side by side did we figure it out - a manufacturing defect had created a "sport" version with the wrong length. Nobody had bothered to check. They had an entire production run that was wrong, and lucky me, i am the one that caught it.

Yikes ��

This sucks you had to deal with this, I've purchased quite a few GKtech control arms including the FUCAs, rear camber arms, and rear traction arms and luckily I've never had a problem as severe as this but it's very concerning. I personally went with GK because obviously, I'm not in a position to afford SPL control arms and personally, I didn't see a significant difference in design between SPC and GK arms so I opted for the cheaper ones. Luckily so far the only real complaint is how difficult it can be to accurately adjust the GK FUCAs compared to that of SPC. I'll probably stick with GK until I can eventually afford a full set of SPL arms but until then here's to hoping I don't run into any serious issues!
