Rear LCA Relo-brackets (with stock ride height)

[MrClean]

Will this help the wheelspin/wheel hop by "pushing" the wheels/tires down onto the tarmac? Will I have increased nose-dive on braking?

Anyone done this?

I have. I have it set to the 2 in setting. It improved my 60ft by a tenth with street tires. Didn't notice any nose-dive during braking either. Im not sure about it helping wheel hop though. I corrected that with upper and lower control arms.

If you're stock ride height, then your LCA's are already set in the correct positions. The stock LCA's are pretty flimsy, so that's what you would like to change in order to help with the wheelhop. Changing the LCA's is all I did originally, and ran the time in my sig like that. (and I was lowered too meaning my LCA angle was worse than yours for traction)

You'll be ok. Mine works just fine. Essentially what you're doing is changing the instant center of the car. Lowering the rear of the bar moved the IC backwards which helps weight transfer.

Thanks for the confirmation, that's what I thought it would do.

Tarmac? its not an airplane lol, and to answer your questions no and no. For stock right height there is not much to be gained, then again it cant hurt and will lower the instant center, and they do not effect brake dive up front. Some stiffer front springs or solid sway bar mounts will help with that.

Thanks for your input!

For the sake of clarity, I don't currently have a problem with brake dive, the question related to nose dive was "will lower rear LCA mounting points on the rear axle increase nose dive".

I understand the fact that lowered cars need the relo brackets to restore the LCAs to parallel-to-ground position, and therefore restore the original Instant Center of the car. However, it seems to me that when we launch a car with "parallel-to-ground LCAs", the rear of the car squats, the LCA portion attached to the chassis moves down, so when that happens the LCAs aren't any longer parallel to the ground (the point attached to the axle is higher) and since the LCAs are essentially being pushed forward by the axle at that point, traction would appear to be compromised. This would appear to happen even more so with stock suspension, which presumably has more travel that a lowered suspension. So what I'm contemplating doing is lowering the point where the LCA attaches to the axle, so when the car tries to squat, the force of the axle pushing the LCA forward will essentially be preventing the squat and exerting more force downward at the tire contact patch.
