So here are the three pieces I got from Ultra Racing. The top piece is the front lower strut bar, the middle piece is the rear lower strut bar, and the bottom piece is the rear upper strut bar. On their website or eBay store, these pieces are all for a Mazda 323 BF.
These pieces shipped VERY quickly, considering they came all the way from Malaysia to the east coast of Virginia. They were wrapped in plastic, then bubble-wrapped, and the ends were wrapped in cardboard and taped. There wasn't a scratch or dent on any of these pieces after I unwrapped them. The pieces themselves seem to be well made, very sturdy, and nicely powdercoated. If I didn't already have a front upper STB, I would've ordered one from them as well. I attempted to install the front lower bar, but couldn't break the bolt loose, so I'm going to have a shop install the front and rear lower bars. I would imagine an impact gun will make quick work of breaking those bolts and nuts loose.
I installed the rear upper bar, and it fit perfectly. Took more time trimming the carpet around the bar than it did to install it:
As has already been mentioned with these products, they don't come with any instructions. But if the fitment of the lower bars is anything like the rear upper one, all I'll have to do is point out where they go and let the shop do the rest. There was one thing with the rear upper bar though that I wasn't expecting. After I got the bar installed and the carpet trimmed, I put away my tools and stuff, and went to close the trunk. Well, that wasn't going to happen, because the bar interfered with the struts being able to move so the trunk could close. I had to remove the struts in order to close the trunk, so now I have to figure out another way to keep the trunk open. I think my first option is to see if a regular prop rod will do the trick. Find a place to anchor it, measure to see how long the rod has to be, then spend some time at Pick and Pull and get one that's close enough.
I road-tested the car after installing the rear upper STB, and what a difference. I could tell right away, the car was MUCH quieter, like having the hard top on quiet. And it felt more "together", unlike the twisting sensation, squeaks, rattles, and other noises it had before. The side windows seem to fit better against the top, so there was a lot less wind noise. The front and back parts of the car seem more connected than before. I'm expecting the car to really be solid after the front and rear lower bars are installed. Might get that done tomorrow. Whenever it's done, I'll try and take some pics, with a road-test impression.
