If you lower your ride 1-1.5" you will need relocation brackets. Traction will suffer badly without them. Spin city and wheel hop!

 

awesome. so maybe ill grab some eibach pro kit springs and the bmr lca's and relocation brackets!

 

Don't forget an adj. panhard bar. A must when lowering.

 

1.5" will def benefit from relo brackets. The LCA must have a downward angle going from frame to rear end, lowering 1.5" will have upward angle which will cause sever traction issues, even parallel is no good.

 

thanks guys. and yeah ill throw in an adj panhard bar too.

 

Not required, but at 1.5" or lower, they are a worthwhile upgrade.

 

Your front alignment will be off a bit as well if you lower it. Mine were at -1.8, but I have a pretty aggressive drop. Shouldn't be by much if its just 1.5", just enough to affect tire wear. Camber bolts (which I don't recommend) or caster/camber plates will solve that.

 

i work at a ford dealership, so getting an alignment done definitely wont be a problem.

 

Just installed the BMR TCA022 LCAs and relocation brackets yesterday. The quality is top notch and the installation is very easy. Can't tell you about improved traction because I haven't tried to launch yet. I did get on it a little in 2nd to see if the LCAs eliminated the wheel hop on the cold pavement and they did. No wheel hop. The ride does seem better and rear seems to have a more of a solid feel and better planted. I am more confident in the rear traction going through curves as I did test it on a couple on/off ramps. Again the rear felt as if it planted to the road much better than the stockers. There is a very slight increase NVH with the spherical bushings but not bad at all. I had to cut the radio and heater off just to hear it and could barely hear it then. If you have loud exhaust or have the radio on slightly, you won't hear it. Sounds like a little rear-end gear whine transferring through the solid bushings. Not a problem though, it's a sports car, not a Cadillac. Don't let the NVH scare you away from spherical bushings, they are worth it and again, you have to try hard to hear it anyway.

OP, I highly suggest these when you get around to doing your suspension.
