If your car is "lowered" you should have mentioned that in the first post.... it makes the answer obvious.

You definitely need LCA relocation brackets. When you lower the car, it places the front end of the LCA (where it attaches to the subframe) lower than the back end of the LCA (where it attaches to the axle). Hence..... when the axle pushes on the LCA, and the LCA pushes in turn on the body (that is the only thing that makes the body move forward), the reaction in the LCA lifts the higher axle end of the LCA, which reduces the load on the tire. The tire has less load, develops less traction, and starts to slip. The instant it starts to slip, the load pushing the LCA forward disappears, the lift on the axle disappears, the load to the tire increases and it regains traction. The cycle starts all over again.... and you get hop, hop, hop.

The objective of the LCA relocation bracket is to keep the axle mounting point below the body mounting point at all times, even when the car squats on launch. A lowered car just makes it even worse. But, you may also need LCA's with firmer bushings. The stock bushings are hollow on the top and the bottom. That allows the ends of the LCA to move up-and-down excessively.... so now you need LCA's and LCA relocation brackets.

I would say that the torque arm and the panhard rod play much less of a role in wheel hop. Solve the LCA problem first, then consider the added advantages of more "lift" at the front of the car from an aftermarket TA, and better side-to-side postioning with an aftermarket PHR.

And, be sure to look into the SPOHN Performance parts... .that is all I use on my car.

SPOHN: LCA's, relocation brackets, TA and sway bar

SJS:

A Moser 12-bolt is not necessarily a "posi".... you could also buy one with a locker or a spool. They would definitely be chirping the tires in turns, as Mir has pointed out.

simple:

Did you use the limited slip additive?
yes it has the LS additive in it! with a locker, i would hear the diff. "unlock" as i went to make a turn right like a clunking almost? thats not what i'm experiencing, i'm feeling the inside wheel kind of drag or hop some as i make the turn, not overwhelmingly or anything but its noticeable for sure! would over tightening the rear suspension components have any thing to do with this?

thanks, Steve
p.s. didnt mean to hijack your thread, just thought it was an appropriate place to ask my questions, since they might be semi related

what kind of parts do you have in your suspeion. like tublar or boxed LCA's,

if your compents are adjustable than they might need to be "played with" and if not the suspeion could be binding. my car does it when i it is a little out of wack and it i make a realy hard turn at low speeds. i can fell the car ind of strugling to operate smoothly. kind of like its not moving(also felt like i overtightened the bolts.

all of my rear suspension is stock (for the time being) I think i might've figured it out, i think i over tightened the rear sway bar where it attaches to the axle tubes, and the weird angle that the stock sway bar is mounted to it might not be letting the rear make complete contact with the ground during a turn, like its suspending it up under the car too much, yep i think thats it, gonna loosen it up some tomorrow and see what she does

thanks
Steve
