strut brace appears to be a cusco strut bar, theyre great equipment, quality brand
and regarding your belt squeal, the belt tensioning system in my opinion is horrible as the tension is held by one bolt threaded into the aluminum alternator on the top which looses its tightness over time as these engines seem to buck more than im used to with other cars. i drilled the threads through and put a through bolt out the other side to really clamp that tensioning piece down to the bracket, and used some blue threadlock to snug it tight too, havent had issues since. your experience may vary as my alternator i had to get replaced as old owner jerryrigged another car brands alternator into it, to which the alternator unbolted from the bottom
