Probably just long enough to open an account and post about how great they are.

Besides new bushings and maybe weight savings what kind of performance upgrade does it provide?

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.

I would say just different bushings and lighter weight.

Here's the FS thread from DNA Motoring.
https://honda-tech.com/forums/wheels-tires-brakes-suspension-48/new-product-j2-engineering-front-lower-control-arm-3174442/

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..

Yay, a pointless mod for the front end of the car now.

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.

This thread is old.

Your lower ball joint is probably what is bad and is squeaking.

No it's not my ball joints. It's the part where the control arms connects to the frame. I've also had a shop confirms it last time I did an alignment.

If these have urethane bushings, they need frequent lubrication. Use synthetic grease, not petroleum based stuff.

These will probably snap in half due to cheap aluminum.

Would not use.

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.

So just installed these on my Da Integra. My issue is the ball joint barely gets tight then spins in the boot. I have brand new oem ball joints,
Steering is sloppy and not right. Am I missing something?

A common problem with these aftermarket front aluminum LCA is that the lower ball joints can't be fastened in place without the use of "spacers" (crush washers?) bought separately; thus you have a car behaving as if the castle nut has chewed through the cotter pin is about to come completely loose. Even the knock offs of eBay refuse to take the opportunity to address this. Possible reason for this "flaw", is that since it's aluminum it has to be a certain amount of thickness. Why not make the ball joint part of the LCA steel? Since it's a bit complicated to weld aluminum to steel, it may not be worth the money and risks for the manufacturer.

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.

I could have sworn the Omni Power front LCA's have a steel bushing in place for the balljoint issues you're talking about.

I stand corrected, but it seems they're out of stock indefinitely.

I've never quite understood why any company would ever brag about 6061 in any suspension part save bushings.

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.

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?

According to Enkei (link), 1 pound of unsprung weight savings is equivalent to reducing overall vehicle weight by 20 lbs; which I'll admit seems a bit exagerated, but seems worthy enough to increasing fuel economy and reducing tire wear. 1st gen NSX used aluminum LCAs in the front.

Unfortunately an
Amazon review Amazon review
, has scared me off from getting them, or at least the sub $100 ones. There are
other reviews other reviews
with similar complaints.

Rear Blackworks ones on my car have been going strong after 2 years.
