I have BBFW NB SD bars in two of my NA’s. I like to support small businesses and Moti is close. Both cars now have a Robbins top with the glass window. The smurf has Nakamae seats which sit 4cm lower but the BRG still has stock seats. I’m 6’ and don’t have issues in either car. I never noticed the welds but probably because I never inspected them. Before I put the hardtop on I always put on the boot cover for longer drives/ car meets etc with no issues.
