i was planning on buying a asr subframe brace and was wondering is there a specific brand thats good with this ? would it really matter the brand ??

 

Well firstoff ASR sells a 24mm rear sway bar for that set up.
And if thats to much, its been made to fit any aftermarket or OEM sway bar.
I just bought the same brace for my Civic and i bought the saw bar with it, its nice because it also comes with end-links.
