Thanks for the updates on the LCA's. These are the last piece of the puzzle for me. I just hope you guys can get them out the door in time for the first LS fest

I just recieved mine and installed them yesterday. They are a very nice piece however I'm kind of frustrated. I've exchanged emails and phone calls several times with BMR over the past few months trying to get these. Even after a shipping mishap, I finally got them. No big deal. But the instructions start off saying I have to use adjustable toe rods with them. Why didn't anyone say something? I don't care about the money, it's just annoying to finally get my parts and have to wait even more for more parts required for the install.

Here is a picture of the arms. I'll get some pictures if them installed today

How much do they weigh each vs the stock.

Sway bars do utilize lever arms at the ends, but once again, these are proportional to their length, which is why the closest hole to the bar is the stiffest setting, and the further out you go, the less efficient they are.

The FE3 bars also appear to have shorter lever arms (more efficient) than the FE4 bars.

So why do people keep posting the FE4 bars are more efficient? Is this just an assumption that bigger/longer is better? Or is there something I'm missing?
The proof is in the pudding. Try putting your finger next to hour thumb straight out vertically and press down with your other finger on your other hand in a perpendicular position then put that same finger further out towards the end of the vertical finger you will notice that the further out the finger pressing down is placed the more effective it is. Yes it is true that the longer the bar the weaker at the end but with a solid or larger diameter hollow bar placed more outboard the more effective. This would also work if we could place the rear shock a tad bit more outward like say .5" or so to still allow tire fitment. The same shock with say a 600lbs spring would be more effective if it was placed more outboard towards the hub.

I didn't weigh them. But they are definitely heavier than stock.

Here is an installed picture. Again these are a very nice piece. I put my factory wheels back on for the time being until I get my toe rods here. I just hope when they get here there isn't another note telling me I need something else for them to work...

Would buying the adjustable LCAs save me the trouble of needing to buy the adjustable toe rods? I already have BMRs non adjustable toe rods.

Sorry for the confusion on your order. I will say in our defense about the adjustable toe rods, it is impossible to know what each customer has or doesn't have already installed on their cars. And it does say in the description for the TCA028's that they do require adjustable toe rods. But yes, if you called in your order to us, then we should have asked if you had the adjustable toe rods to go with them. If that didn't happen, I do sincerely apologize.

I know you got your answer in another thread, but just in case anyone else sees this and is curious....

The stock (OEM) LCA weighs 5.7 lbs.
The TCA028 LCA weighs about 7.0 lbs.

1.3 lbs. per side isn't that bad for the amount of increased structural strength you're getting from these TCA028's.

The TCA029's will probably weigh a pound or two more because of the large chromoly adjuster nut in the middle. Just my guess....didn't have any unboxed to weigh at the time.

And yes, you are correct, with the Adjustable TCA029's, you do not absolutely need the adjustable toe rods. Nice to have....Yes!!! But required....No.

Kieth, no problem man. You've been a big help. I'm actually installing my toe rods I just got from you right now. I'm almost done with the install.

I was a little worried about lowering the cradle but as you can see in the pic, it's not that bad. Thanks again Keith!

I just ordered TCA029 since I need more camber in the back. Do I also need adjustable toe rods to make them work correctly?

No, you can use either the adjustable or non-adjustable toe rods with the TCA029's.

Just to clarify, can one use TCA029s to increase max negative camber without using an aftermarket toe rod, with no ill effects?

TCA029's will certainly allow you to increase negative camber beyond the limits of the factory eccentrics. And yes, you can use the factory toe rods in combination with the TCA029's, but an aftermarket toe rod (even non-adjustable) would be vast improvement over the factory piece. In my opinion, do it right the first time….get adjustable toe rods. You're going to need an alignment after changing the LCA's, and you'll need another alignment when you change toe rods, might as well do them both at the same time. Now how you choose to use that negative camber and how it affects your car will decide if it will be a positive experience or negative.

I already have the OEM Z/28 toe rods (that came with the suspension kit), though. I'd rather keep it, and just get the control arm for camber. So I presume it would work well with that rod?

I'm going to try aftermarket bolts to get more camber, next week. If it fails, I'll order the control arm. I'd get it right away actually, but I don't want to add weight to the suspension if I don't have to.

I've also heard that pedders bolts can let you get to pretty aggressive camber, but I don't know if anyone still sells them, or if there's any similar product. My bolts are SPC/Eibach brand.
