Default LCA relocation bracket trouble :(

got the brackets on the car and it is EXTREMELY stiff.
will not squat anymore.
you push on the hatch and the car is rock solid.
drives down the road like my 3/4 ton truck. high speeds seem very unsafe to me now. car roars like im riding on a flat tire. i really cant explain it.
car has always ridden like a cadillac, even with skinnys and et streets.
no other parts were changed.
loosed the back bolt on the lca, hooked it to the bracket and welded it in place.
im puzzled. i was hoping for every bit of ET i could get out of my setup, now im ready to burn it.

Can that change your torq arm/rear end angle to make it like that? I know you had it set at -3 b4 you added the relocation brackets! So do you think that would have anything to do with it?

mine is the same way, and i love it.

the brackets made your control arms drag oriented, so youre gonna have that added stiffness.

i ended up adjusting it down to -2 a while back. a lil less vibration and it still 60 ft's the same.
i doubled checked pinion angle just to be sure, and its still -2. checked the spohn instructions and talked to 2 different drag racing buddies(matt....brandon) and its set right, AFAIK.

Did you torque them with it on the ground with all the weight on it? Or in the air not at ride height?

i think UMI calls for 72ft lbs loaded suspension. you cant really put the car on the ground and tighten the bolts, so have the rear end sitting on jackstands and load the weight down on them.

What hole do you have the LCA's in? What angle are the LCA's at now? Parallel or pointing up?

lca is in the downward most hole.
the bar is up in the front, and angled down on the rearend side.
going out there shortly to see if i can figure something out.

if you put on bolt on's, why not take them off and see if that changes anything? or try the next hole up to see how it reacts? process of elemination.

bolt on's welded into place. sleep better at night knowing its welded.
lca fell out of the bracket once i took the bolt out, so they werent over torqued or in a bind at all.

problem has been fixed!

made my own shock relocation brackets for the rear, and the bolts i used were just a shade too long. my anti roll bar was sitting on the bolt, not allowing for any flex.
stupid me, but i didnt notice it the 1st time.
when the car was in the air for inspection, the sway bar is no where near it, but once loaded, it was setting on the end of the bolt.
DOH!
thanks for all the help.
depending on the size(or brand) of your sway bar, make sure you use a bolt thats near perfect size. for the shock brackets.

" made my own shock relocation brackets for the rear,"

Do you have a picture? Do you mean you changed where the shock attaches at the lower end? Why? Not to be a smarty pants just trying to learn and understand.

madman sells them. it turns the shock to free it up. the way its bolted to the rearend puts somewhat of a load on the shock when you adjust pinion angle.
i just wanted to save a buck from buying them. of course if i would have used his brackets, id have the correct length bolt the 1st time.

they are on thunder racings site to get you an idea. lots of people converting over to them.
all in all id say the LCA relocation brackets work.
havent been to the track, but with a gear change, i ran into some traction issues.
it didnt cure it, but the car doesnt blow the tires off at such a low roll anymore. so they are putting a lil more force on the tires.
