Negative feedback for K Sport USA

[BrownDogg]

Negative feedback for K Sport. I bought their front camber arm which is also the front upper a-arm on an Infiniti G35. Part # CKNS04

I installed these camber arms on my Infiniti G35 back at the end of November 2009 and had them on the car for about 4000 miles in total. I installed coilovers on the car and noticed that the powder coat was chipping off of the a-arm right around the adjustable camber plate. I further examined the arms and noticed that they were actually bent which is why the powder coating chipped off.

I notified an employee that works at K Sport of this issue and I brought the car into K Sport and put it up on their lift so they could see the bent a-arms. K Sport at first said it might have happened because I was lowering on just lowering springs instead of coilovers so the car had more body and moved around more causing them to bend.

If that was the case, it shouldn't matter because these camber arms were designed for lowered cars. There is absolutely no point of having these arms unless your car is lowered so that makes no sense. They stated they were not going to warranty them because they have never seen this problem before.

I took the a-arms off the car a few weeks later and noticed that they were in fact a lot more messed up that I originally thought. They bent in multiple places which should definitely not happen. As you can see in the pictures below, they bent a good amount and it is clearly a failed piece of equipment for my car. I took the front a-arms/camber arms into K Sport and showed them how bad they bent and they still said they were not going to warranty them because they have never seen this issue before.

The most logical reason they haven't seen any bad a-arms is because the average person would have never noticed that they were bent. The a-arms still functioned on the car and the car was still completely drivable with them. The average person would buy these arms, take them to a shop and have them installed and then aligned and never look under the car to see them. You can't really see them once they are on the car anyways.

To me this is a big safety concern. If they failed and the metal bent that much in that short of time span, imagine how badly these would look after being on the car many more miles. 50K-100K miles they probably would have snapped off. What if they would have completely failed while I was driving or drifting at the race track? The damages would be horrific let alone my safety in jeopardy.

While I was at K Sport comparing my defective camber arms to a new set that they had on the shelf. One of the BRAND NEW never installed a-arms was bent in the same place as mine before it was even installed! So this is clearly a weak spot in the design of this product.

This just goes to show how poor their customer service is. I have bought lots of K Sport products in the past. I have had their coilovers on my 1993 240sx, coilovers on my 1996 240sx as well as every suspension component offered by K Sport on my S14. Coilovers on my G35 as well as every other suspension component they make for my car. I have always had good things to say about them until now when their product failed on me. It appears as though they cut costs on the quality of the materials being used to make their suspension components because these a arms bent in almost every possible place that they could have. It really makes me angry knowing that I have owned so many of their products and have said so many good things about K Sport and how their quality has changed and they finally make a solid product but apparently I was wrong.

This product that I purchased new retails for $570! I sure would like to think that a camber arm that costs that much is not going to fail on me. I bet Cusco, Tein, Spc, and other companies products do not fail on them like this.

I can assure you that these did not bend due to my driving being careless or something along those lines. I am a very careful driver and am always on the lookout for potholes. If only 1 side was bent then I could see K Sport blaming the failure on me but since both arms are bent in the same places, this is clearly an issue.

Cliff notes for those that don't like to read:

1) Bought K Sport front upper a arms/camber arms.2) K Sports product failed on me3) K Sport refuses to warranty their defective product4) I am stuck with almost $600 paper weights

The Pictures:

You can see all the spots in the arm that bent by looking at the powder coating that is cracked at each bend.

Picture of the arms before I installed them so you can see that I did in fact purchase them brand new and never installed.



Here are the pictures of the bent cheap quality arms

Damn! Well I'm glad you're OK and they didn't completely fail! Too bad about losing your $$ on a crappy, unsafe product.

Thanks for sharing.

Was this ever experienced by anyone else? I "WAS" going to get the coilovers for my M35x but now?!?!
