My brohter and i made a homemade rear strut tower bar with seat belt adaptors. I bought a cheap ebay front bar and modified the hell out of it. We cut and grinded out the mounts to fit and rewelded the attachement bracket. We bought new piping and welded the bar itself. We welded on mounts for the seat belts. It looks good and still alows me to have rear storeage in my car.

As you can see the welds are very clean and strong. I'm not worried at all about it breaking. The bar is high enought that if i crash my spine won't be crushed. So i'm happy. It only cost around $40 and a full day or working. But we work slow.

Id be worred about your shoulder harness installation. The general rule is to keep the anchor points of the shoulder harness at the same level as your shoulders. If they are too low, if you get into an accident you will snap both your collarbones.

The local rotary expert at AIM tuning, a RX-7 speciality shop, who races SCCA and won his category last season in his A-spec miata said that the location for the bar would be suitable race use and daily driving. I trust his judgement because his racing background would not put a persons safety in jeopardy. You can find his site at www.aimtuning.com

pull an 11 second pass and see how long they let you keep running at the track with it being below the shoulder line. trust me, it wont. i have a similar setup except for my bar is higher up as to allow it just above my shoulders. ill have pics later. and ill be fabricating these bars and selling them for $80. primered, bolts into the same location you have yours.

well, im not big into drag raceing and i don't think my car can do an 11 second pass. But the scca will allow it. I've seen worse set-ups allowed race. So i'm not worried. It does hold you in your seat really well. I took a couple of fast turns last night and i'm loving it.
