BMR LCA Drop Bracket...Heads up to everyone

stanglifemike · November 2nd, 2009, 12:38 AM

Nice!! I may take you up on that, may do it on the alignment rack too.....I'm so indecisive. Have to do it before MCE day though!! Need to come by and see those wheels/tires too

Was that your car JW?

Anyway, glad you got it all worked out and nothing was hurt.

Also. Before I adjusted anything I measured from the front of the lca mount to the top bolt on the bmr bracket. There was 1/4" difference from one side to the other. one was 18.5" and the other was 18.75". The axle was in a twisted situation but was corrected when I readjusted the brackets. You have to be careful when adjusting these. You need to make the same turn from side to side otherwise they will be out of alingment form each other. I kept measuring and counting turns to ensure they were equal length from the front LCA mount.

Also, since one side had moved and the other wasn't the pinion was still off. After i got it all aligned up I had negative 4 degree on the axle and negative 1 on the input shaft of the rear end.

The photo was taken with my iphone so t's not the best. Functional for sure but not the best form.

Mike. I am sure my neighbor will loan it to me to help you out. We should weld those in before the MCE day on the 21st.

Yeah, that was my car. I was having trouble with the driver side front tire coming up (cool looking but I didn't want the chassis flex) so I removed the rear sway bar and put in the BMR XTreme antisway bar kit so I'd have even launches. My son was driving and we had the ET Street Radial tires set at 17psi, the QA1 shocks about half way, and dumping the clutch at 6k. Well, the f***er hooked like it was supposed to and the bracket gave way. Here's normal and the damaged one:

We definitely recommend welding them. Its sounds to me like the bolts loosened up and the bracket moved. If they were tight the brackets would have ended up like jwgroovin's. If you have any further issues let me know.

Wow so your the legendary "bent the bracket" guy. That picture is one of the most past around pictures on the net. How many hits does it have? n/a to, what was the 60 foot that did that?

I had speculated that someone backed the car into a curb or something and did that but since its you ill give it a legit stamp.

Thats what i was thinking.

View the Anti-Squat Brackets<BR>Part # CHE1L at http://www.cheperformance.com

does anyone have experience with the CHE brackets? they say no welding required, but from everything I've read about LCA drop brackets welding is a must, so I don't know why these are different...

jwgroovin · November 2nd, 2009, 06:54 PM

That bracket took two weekends worth of hits while we worked on dialing in the shocks, tire pressure and launch RPMs. Consistent 1.62-1.65s all day long. When Zach (my son) hooked on that last run, I'm betting it would have been an easy 1.5x. the front end lifted, the left front tire got air (street wheels, not my Bogarts!!!!), the rear planted and BANG! That rear tire rotated forward into the wheel well lip:

Lesson learned. Figured I could get by without welding for a couple of trips to the track, but even 348hp NA and a great hook is enough to collapse the bracket.

I have them, but my useage on them is worthless, I haven't been to the track yet. The CHE brackets are beefy as heck, there isn't any route for them to swivel and when I begin consistently launching with slicks and high rpm drops, I'll still weld them in.

They won't bend nearly as readily as the BMR design (steel plate looks thicker and doesn't have that long stretch of metal to bend up, it's all boxed in) and they have lock channels to fit into place so they won't rotate. But, what's it take to weld them in?

Besides, the CHE brackets only have one mounting hole, whereas the BMR and other designs have flexibility (no pun intended) for their usage.

jwgroovin · November 2nd, 2009, 07:37 PM

BMR. While I bolted them in, I didn't follow up with welding as indicated in the directions and paid the price. Remember, do it right the first time...

Anthony05GT · November 2nd, 2009, 08:10 PM

It's wise to weld in any LCA relocation bracket.

You know. I should have called BMR the day I installed these. The locknuts that are sent with the kit had issues. The 2 bolts that clamp onto the axle bracket stripped out the nut. The bolt was fine but the nut stripped out. I looked everywhere around town and could not find nuts that fit. They are metric i suspect. I had some similar bolts left over from another project and used them. These were just long enough and slightly smaller. I thought they would have been ok but that might have played a part in all this.

Maybe I can get replacment nuts sent out to me and i will replace the bolts I used with the BMR included bolts.

I recall when i did the upgrade being short on time and anxious to get to the track. Lesson learned...do it right the first time.

07stanggt · November 2nd, 2009, 11:51 PM

Smaller diameter. Ok thats how it can move and not bend. Yea Dennis can help you.

I am interested in this since rear end noise has been a problem for me.

But im confused.

So the bracket moved forward towards the front of the car? Or backwards?

lol I knew u would go crazy for this one... your the original ass man of MM lol

love you bitch

ethrjock · November 3rd, 2009, 02:59 AM

Update. After resetting the pinion angle to neg 3 degrees the drive train noise was eliminated. Gone. Musta been the angle.

Someone asked why I needed to adjust each LCA equal amounts. That since I have the adjustable LCAs. You have to turn each adjustment nut equal amounts otherwise one will be longer than the other causing your axle to be slightly twisted. I also measured from a fixed point on the body to the center of the bolt that clamps the LCA to the axle mounting tab to make sure they were equal distance as I measured for the pinion angle.

qwik48r · November 3rd, 2009, 03:01 AM

rich is gonna be very interested in this when he reads it... I rep'd ya for that info man, thank you for your research and diligance!!

kenneth · November 3rd, 2009, 10:17 AM

Last season I was cutting 1.6xx 60's without them welded in, but I was running them in the top hole on the relocation brackets.
last week I dropped them to the bottom hole and had them welded in, hopefully next week we will see what kind of difference it made.

Also added Cobra Jet rear springs.

BMR Sales · November 3rd, 2009, 12:29 PM

Your car should 60' much better with the arms in a lower hole. Let us know the results of your next trip to the track.

yeah i have mine welded with my mig welder with my LCA's in the bottom hole...but i have the Roush springs in the rear

On BMR's site they have a video with a vert 05 on the stock BFG tires...with the brackets at the bottom hole and their LCA's it got into the 1.8x's on the 60'...damn impressive on those shitty street tires..so i can't wait to see what this saturday is going to be like with the the steeda chromoly LCA, UCA..QA1 shocks..BMR panhard and brace..rear roush springs..325/45 M&H's and skinnies. Its going to be fun im sure..
