Strut tower braces and factory strut bolts.
Hi,
I own a 94 legacy wagon, and for want of more productive things to do a fabricated my own front a rear strut tower braces. I used 1/8" flat stock to form the base plates, a 7/8" .156" wall DOM tube, threaded for right and left hand threads either side, and rod ends with right and left hand threads for adjustability and removeability (especially important if I want to use the cargo space in back on occasion). My question is this. I mounted the base plates to the strut tops by running the strut studs in the top through holes in the plates. Can the factory studs and bolts there take the kind of sheering force that brace can exert, or am I likely to have some neat clunking sounds soon? Thanks for any advice, Regards, Roy

I just installed a Whiteline rear strut brace in my 02 WRX wagon 2 weeks ago and so far have had no noise or movement of the bar or brackets.

As long as you have a close fit with the holes in your base plate and the strut studs, you won't have a problem. Remember not to over torque the strut stud nuts. As far as shear is concerned, you have three studs that theoretically share the load per side, but since it's a beam, you have equal loads on both sides, so you have six studs to share the load. You'd need a pretty big force and small surface area imparting that force to shear all the bolts. The base plate would probably deform before the studs sheared depending on the hardness of the material you used for the base plates.

Thanks for the thoughts on the shared load there, it reassures me quite a lot. |

With materials (about 1.5 square feet of 1/8" mild steel was required, along with ~7' of that DOM tubing a 2.22 a foot, and rod ends at ~$7 a piece) the two cost me all of around $60 or so, which is way more that I intended to spend. I did my own metal work and welding. |
