Yes, as it's probably the cheapest way to gain real caster, which this car desperately needs. Also, there is a slight camber gain. You will need an alignment because this will change the front geometry, and the front half-shafts, as a benefit, will line up better with the front diff centerline/driveline.
You can run the stock arm no changes, or you can install the whiteline kits. The rear bushing is the issue, but that is fixable, with some effort. You could run with the inside bushing and the roll-center kit only, and just use the stock rear bushing. Everything will bolt right up.
Some people might wonder, "Why go through all the trouble of LCA bushing installs and the upper strut mount change?" If you notice in the video, my wheel assemble NEVER moves out of alignment under acceleration and braking load inputs, which translates into no camber,caster,toe changes! This would cause under steer most of the time.
I will be tracking this setup sometime in the spring, so more to come. I currently run zero toe up front and zero toe in the rear. Camber is set at about a little under negative two, front and rear. I don't know what the front caster is yet, but I'm pretty sure it's double the stock value. I don't feel any bump-steer, but there is a little off throttle oversteer, which I like. Some things might change because I still have stiff walled advan AD08s to install in the spring.
I really need to start a build thread, but I wouldn't know where to begin...
