Happy New Year everyone, I'm buying a rear SPC camber arm and found 2 part numbers that fit our sedans, 72260 and 72280. Can somebody point out the difference and which one I should go with?
Thanks in advance.

Check w/ SPC suspension site, looks like they only list 72260

72260 = g35

72280 = g37

When I enter the G37 in the SPC link it only lists these numbers for all their rear camber parts 72260, 72262, 72265

Using the link provided, I enter 72260 in the part number search applet and it gives me a blurb about it being a G35 application. On the same applet, entering 72280 results in an application for G37.

The kit I bought for my G37 is 72260 (just went downstairs to look at the box).

Using the application search, for G35 and G37 is 72260.

Now I am confused.

It's quite possible the application guide is dated and that 72280 has replaced that 72260 setup. The 72260 will work, unless they've changed it too. Might give a call to SPC prior to installing just to be sure, and please post whatever you find out as this would be good info to share.

Edit~Check this thread, it's been a while so I'm not sure if anything has changed since then, looks like the 72280 is the older curved design (this is what I have on my sedan) and the 72260 is straight. Seems like there's still some confusion here. Again, I'd call SPC and find out for sure.

Ah yes... totally forgot about that thread. Well, here is another: https://www.myg37.com/forums/brakes-...mber-arms.html See post #7

Sounds like you'd want the curved one if you've got or are planning to get aftermarket Sways too. Just to complicate things, lol.

I wasn't thinking about sways... but the OP may have been. I'll check with my vendor Monday and see what is up.

Let us know what turns up, it's too bad there seems to be this gray area

I have sent a message to SPC and hopefully will hear from them next week. I went to my vendor's website and lo and behold; in the part's title it shows 72280, in the part's description shows 72260.

Reading that description, the sentence "SPC Pro-Alignment Rear Camber / Toe Kit for 08+ Infiniti G37 (w/o active steering) Coupe/Sedan. The 72260 Adjustable Rear Arm for the Infiniti G35 offers maximum adjustment for camber and toe." stands out. Either a typo or just horrible general confusion. Either way, I am just waiting for SPC.

Guys thank you both for your help
I found the same thread
Difference between SPC 72260 & 72280 - Rear Camber Arms
72280 is a shorter version, 72260 is a straight version, 72262 has a better bushing call xAxis. Some members had issues with 72280 because SPC replace the curve version by a straight one(apparently due to quality issues), people with thick aftermarket sways have problems cause it hit the sway. I saw a picture on another thread can remember which one.
72265 are bolts according to SPC website:
The 72265 Rear Kit offers adjustment for the Infiniti G35. These cams replace the OE camber and to adjustment cams and provide additional camber (±2.0°) and toe (±2.0°) changes. Adjustment slots will need to be elongated using the 85130 rotary file set or equivalent. This is the perfect kit to adjust rear alignment angles for optimum handling and maximize tire life.
It seems 72260 and 72262 are the corrects parts.
I will know when I install...

Thank for the advice, didn't really though about SPL sine I don't track the car, but will consider that too. I have one final question, which hole should I elongate? the one for the SPC arm or the one for the suspension arm, the later makes more sense to me since the arm itself can be elongated or shortened. SPC has an installation video elongating the suspension arm, in YouTube I found a video elongating the SPC arm hole which I don't see the point. Can someone clarify?

If you have the camber arm w/ toe bolt set you ONLY elongate the toe bolt slot, and you only need to elongate to the inner side of slot (the side facing the driveshaft/differential) the outer side of the template will increase your toe and you don't need that. The camber arm just uses your OEM bolt, since you're adjusting with the arm now and not the bolt.
Also a good idea to lengthen/shorten your new arm to roughly the same length as your OEM arm, this will get you to your alignment shop safer then if you just put the arm in blind.
