Why relocate my LCA's?

[eddieveddie85]

Someone please help me out here I'm in the process of buying up some suspension mods for one big install and am obviously going to buy some LCA's. But what is the benefit of relocating the rear mount? I mean I understand what the LCA's do and the benefit of have a stonger set but still a little confused about the relocation thing. :shrug:

If you lower the vehicle, it is essentially raising the rear axle up into the car. In doing so your control arms (both upper and lower) are now pointing up towards the rear. You really want them closer to pointing straight forward.

I see I see....so the more level the control arm the better?

What are the best recommended relocation brackets that don't require welding?

BMR Anti-Wheel Hop Package w/ Tubular Lower Control Arms (2005-2011) - Revan Racing, Inc.

I was looking at getting this kit, I think these are bolt in.

If you're really going to work those lower control arms, they need to be welded in addition to bolted. I've seen a lot of the brackets twist and/or break.

As simple visual as to why you need them:

On a stock car the forward lower control arm mount point is slightly higher than the rear. As you lower the car, either through mods or the rear squat on a launch, the lca becomes parallel to the ground, perhaps even higher in the rear than front. You need to get it back where the front mounting point is parallel or higher. Thus, extending the rear mounting point toward the ground.

When you say "work the control arms" do you mean like hard drag racing?

Like drag racing on a sticky tire. Which is pretty much the reason people relocate their lowers. I lowered my old 2011 1.5" and still never got a hint of wheel hop with the stock suspension.

 

[eddieveddie85]

Well my car might see a drag stip a few times but never on slicks. I got some K spring which is 1.5, so I think I will just get some arm's and hold off on relocating them.

 

[acrbill]

Just lower the car and see how it reacts. I have a Panhard bar sitting in the box since I did not want to add any hard bushings since they tend to increase NVH. Worst case is you buy the arms later.

One thing not clearly mentioned with the relo brackets is instant center. By lowering the LCA rear mounting point, it changes the car's instant center allowing the rear tires to plant better. Google instant center relocation brackets and you will find a more detailed explanation.

For the brackets themselves, I have been using the CHE pieces. They are bolt in, very durable and have launched the car at 6K on slicks and they held fine. In fact, on that launch, the drivers side axle twisted in half from the shock and force of the launch if that helps paint the picture.

Instant Center is a big deal if you want to dig or drag race.

 

[eddieveddie85]

Thanks, Alot of useful info in here.

 

[eddieveddie85]

oh and what does "NVH" mean?

 

[acrbill]

oh and what does "NVH" mean?

Noise, vibration and harshness.

Didn't your car have stock springs? Could you use these as relocation brackets on a lowered car? Also did they interfere with your swaybar relocation brackets?

I just got k springs for my car and before putting them on I want to get a panhard bar and relocation brackets. Also, are my gt500 lcas worth keeping or should I upgrade those too?

They also greatly assist in reducing wheel hop. I installed UMI relocation brackets and cured about 90% of my dry pavement wheel hop issues. Next up is a new set of LCAs and it should be done. I have had no issues with mine, other than needing to do a loosen and re-torque to rectify some clunking I had. You have to make sure everything is loose and the suspension is loaded before you tighten them fully.

I recommend them, but it is your call.

I plan on getting a set before spring...

Yes on stock springs. Absolutely can use on a lowered car. They will help place the rear suspension geometry back into symmetry after being lowered.

My swaybar did rub the relo brackets. I am using both the CHE sway bar relo brackets and the LCA relo brackets.

For the LCA's, it depends on your goals. I would keep them for now and see how they work. If you feel the need for something stiffer, I would use poly ended LCA's.

Hope that helps. :beer:
