Hmm, if they're shortened then it would offer some camber correction. Without measuring it looks like weight savings alone. I wonder how they hold up to an impact. That's something that has delayed Function 7 releasing theirs to market.

Here's the FS thread from DNA Motoring.

I honestly would not trust these arms on my car. Like mentioned, I would really question their integrity in an accident or track conditions. Everything from J2 Engineering looks like cheap, knock off garbage. IMO, I'd hold off for the F7 arms..

Re: J2 Front Lower Control Arm
I've always wondered how people with these aluminum arms get their ball joint out. I always give my factory LCAs a few good wacks with a hammer and they come loose. seems like you would have to use a ball joint fork and mess the boots all up with these. I know the old omnis specifically said you have to use the fork.

Btw op, it looks like you're coilovers are installed incorrectly. The piece on the sleeves right under the spring perch should be at the edge of the shock body/bottom part of the threads.

don't bother with these LCA, they're junk. I have them on my gsr and they squeak really bad! I will soon upload a video on YouTube showing how bad they squeak really annoying. I even tried lubricating them, but still didn't solve the problem.

Re: J2 Front Lower Control Arm
i have had these on my car for 2 years now without any issues. car is making well over 500hp and they are holding up fine. i just bought them since i didnt want to deal with having to install new bushings in my oem units.

Re: J2 Front Lower Control Arm
Need to replace left & right front control arms (have cracks) on my '06 Honda Pilot. If I order non-OEM there's significant savings. Can anyone recommend a good brand and or site? I know nothing about cars. Hoping this car can last for another 1-2 years and then be sold. Any suggestions would be appreciated. Thanks.

Re: J2 Front Lower Control Arm
Only worthy aftermarket mod for the front LCAs of Integra's and related civics seems to be the spherical bushings ($250 on ebay for the bushings alone), which will allow one to use the Whiteline Caster kit to the full 2.5° without worrying too much about bushing damage. With spherical rear trailing arm bushings, you need not worry about clocking it before installation. Keep in mind, strut's damper angle will be affected with the Whiteline kit, thus decreasing it's life span.

7075 is significantly stronger and really not much more expensive material-wise regardless of the increase in safety factor.
There's a good chance the failures the J2 arms have had wouldn't have happened if they had used actual structural aluminum.

Re: J2 Front Lower Control Arm
OEM's use steel sleeves in their aluminum arms and spindles (even for cast iron arms at times) for ball joint bores.
6061 T6 has close to the same yield point as 65-45-12 iron (not sure what iron they use for LCA's...but 65-45-12 is a decent guess).
It likely doesn't have the same (12%) elasticity or harness, though. So it can benefit from a steel sleeve for the ball joint bore.
Why are people going with aftermarket LCA's for street use anyway? Y'all crazy? Or just needed something to spend money on?

Unfortunately an , has scared me off from getting them, or at least the sub $100 ones. There are with similar complaints.
Rear Blackworks ones on my car have been going strong after 2 years.
