A strut brace isn't gonna make much difference in a straight line, but as badazz said, if you've already got one installed, there's not much point in ditching it now.
You'll really notice the brace when it comes to cornering as it tightens up the flex that occurs at the top of the suspension turrets helping to eliminate understeer in the process

The place I noticed the biggest difference was when I was stopping. Less nose dive, and subsequently I don't notice weight transfer as much. I later put my battery in the back and noticed it again.

the trouble with a strut brace I find, is that you notice it more when its not there after driving with one fitted to a vehicle then when you fit one to a vehicle that hasnt had one in the past. Keep it and rest easy...

I have an adjustable Spohn brace that pre-tensions the shock towers and I definitely felt a difference after installing it. Less flex... on the other hand drag racers usually like some flex to help with weight transfer?

well the main reason i wanna ditch it is because i wanna install a direct port system and its kinda in the way. id just sell it and put the money towards the dp kit basically.
just wasnt sure if it really helped much launching or anything

Here's a thought to ponder for a minute. What is the actual job of a rear lower control arm? Answer, to keep the rear moving smoothly in a centered arc. It's not supposed to inhibit the movement of the rear from moving in that arc at all, that's the shock and springs job, along with the sway bar. When you put poly bushings in the lower control arm joints, they will bind, maybe not at first, but eventually they will bind, which will make the job of the spring, shock and sway bar impossible to do accurately.
To control wheel hop, sideways takeoff, fishtailing etc, look at the shocks, springs, torque arm and panhard bar first before looking at the lower control arms. Control arms aren't meant to impede the upward or downward movement of the rear. Do you want better traction? Go with a larger rear sway, softer springs, and control the rebound on the shocks. This will allow the rear to squat and go. The lca's just keep the axle square to the chasis.
Ever work out? Ever use any kind of arc movement machine with wieghts? Bench press, leg extension etc? Do you want the joints to be smooth moving or do you want them to have friction? Same thing with lower control arms, you want them to have smooth movement and poly bushings bind, period, even with lots of grease, they will still bind once the grease pushes out.

Many people don't consider that when cornering, the body and axle "twist" in opposite directions to each other... i.e. the rear lca's are subjected to a twisting motion, and if the lca bushings do not "give", then they will bind, preventing the swing motion of the lca's as you said, and perhaps bend the lca mounting flanges.

lol... ok, I did say "perhaps"... 
...I have seen a bent tab, I guess I assumed its cause.
rethinking about it... if the lca's front bushing is poly then the lca can't twist in front (ok, yep you're right, no bending)... and if the rear bushing is poly then the lca can't twist in rear... so the lca itself twists, limiting the swing/arc motion...
hmmm, what happens if the lca has been boxed in to prevent twisting...?
ha ha, I'll take a set of those tire too.
