Do lca relocation brackets effect handling?

My car has a pro kit on it and it sits pretty low. You can maybe fit one finger in the front and two in the back between the tire and the body. I just installed relocation brackets with my stock lca's (for now until I find some bmr tubulars) on the lowest bolt position. Is it going to kill my handling at high speeds? I'm figuring that it can't do that much because I'm just returning the lca position back to or close to stock. So whats the consensus?

Would a larger rear sway bar offset any loss from relocation brackets?

The handling guru's in the autocross section will tell you that poly bushings in LCAs can cause the suspension to bind. This would only be seen in radical steering conditions. The stock rubber bushings give and thus do not cause binding. I bought Global West tubular LCAs with the poly on one end and a sperical joint on the other end. These won't cause binding as the sperical joint provides the freedom and aren't as noisey (vibration) as the dual sperical joint LCAs.

I am more inclined to AX and RR, and I can say that I was quite impressed with the increase in rear grip, especially when cornering, from the LCA relo brakcets. Actually, I was quite astonished.

Why have I heard people say otherwise??? I mean logically I would tend to agree with you that relocation brackets would give more grip because they are pushing down harder on the wheels. But people say that at higher speeds and long sweeping turns that lca relocation brackets can hinder your cars handling.

I wouldn't really think it would affect handling all that much since it just changes the vertical position of the arm and not the horizontal position which I would think would have more to do with handling. I'm sure someone will correct me if I'm wrong but I didn't notice any less handling by putting on LCA rel. brackets.

I installed the LCA relo brackets in order to restore the LCA to its original plane after installing lowering springs. All I really accomplished was to correct a less than desirable suspension geometry that was introduced by me with the lower springs. Given the nature and purpose of this mod, I don't see how it could be a detriment to handling under any circumstance. I simply restored the balance that the General had built in. I'm very happy with the result.

Did you use the upper or lower holes on the Relocation Bracket?

I'm curious too because I did mine 2 weeks ago and I was told by a lot of guys that it would create oversteering and it wasn't good for handling.

I just read the threads in the AutoCross section. The LCAs should be level. Measure at the front LCA joint on the body and the LCA at the axle.

0"-0.5" varience in height is acceptable for AutoCross.
0.5"-2" is desirable for Drag Racing.

Since I run through the canyons, I'm going for the near level front and rear LCA measurement.

By the way, if the rear measure is higher than the front, that is an understeer.

If the rear is lower than the front, that can create an oversteer.

Most drag guys won't even care about that which is why it is squishy or loose when they use the lowest hole.

wonder if it would be okay to move them back and forth every now and then. Like when I put on my stickys, change the position as well. When I take off the stickys just put them back. Should be.

I put lca relocation brackets on my carthats at stock ride height the rear of the control arm is 3 inches lower than the front and for road racing i love it helped with the understeer alot. with just an adjustable panhard rod, some wide street tires, and the relocation brackets I was running 2--3 seconds a lap faster than a new 911 turbo at willow springs yesterday.

The rear of the LCA that connects to the axle was 3 inches lower than the front? On an F-Bod that should make it loose not understeer. I'm not familiar with a carthats... sorry.

Yes, you can raise and lower at any time you want.

Well.....bud was racing and going faster so I guess it must work.

Hey Suburban....how much faster did your personal times get?

Depends what result you want. If you want to go drag racing and get a harder launch set for an angle up towards the frame. If you want to induce a bit of oversteer, do the same. If you want a more neutral handling for street and road activity go for a level LCA. I used the hole closest to the axle with a 1.5 inch drop and still have a weeeeee bit of incline upwards toward the frame.
