Strut Brace

I've got a strut brace. Fairly lightweight. Non-triangulated. I've never used it. The car is getting the Rebel Racing bump steer kit and raised spindles, custom valved shocks and new tires/wheels. Street car. For....'spirited' driving.

Should I even use this? Is there a difference? If so, then when I take the car in for alignment and corner balancing, should the strut brace be on the car? Should the alignment guys tension it a bit while they do the alignment/corner balancing?

do not use bolt-in strut brace.
the torsinal force is working on the shock tower bolts. not good. not efficient.

if, then install the rsr weld-in strut brace.
like this:

I know the weld-in versions were preferred by the factory. However, if a bolt-in version is used, then I am not sure why there would be a problem unless the stresses cause the shock tower plate to move, changing the alignment. If the bolt, and plate, do not move, then why would a bolt-in version be a problem?

Also, I wonder if a strut brace should be tensioned or, alternatively, if it should be installed 'neutral.'

I can't find a link with a half-ashed search, but I'm pretty sure I read that our towers spread apart under load. Therefore, I have my brace lightly tensioned. Not confident it does much but lower my frunk space, but I made it for $15 and it doesn't hurt so I leave it in.

Just replied about corner balance and alignment. Yes, strut tower brace when getting your car corner balance and aligned. the suspension mods and corner balance and alignment will make a big difference. you'll enjoy much more
