I'm talking with a fabricator that already makes sturdy-looking STBs for other BMW models. I opened talks concerning braces specifically for the MZ3s but he would prefer to make one brace for all models, but from what I gather the 1.9 models may be SOL under this plan, due to a different requirement (please correct me if I'm wrong).
Ideally, if there are any 'festers in the Simi Valley area, you could be an R&D vehicle for the shop. This would (obviously) be the preferred method for him and us. Please PM me if applicable and interested.
The bars are 1 piece design, and as I said very rigid in appearance. The most likely applicable model I have seen so far is this (for an E36 M3 with ASC/traction):


What I would like to gather is examples of the board's favorite STBs currently available, and this gentleman may obtain one for fitment. I know the Strong Strut is a perennial fav, and Cosmo Racing's bar is used by a few on here. Any others out there that you guys use and like, or specific fitment trouble reports/issues you could site would be great.
Personally, I think these bars would be a killer addition to the community of Z3ers. He already does bars in alloy and steel, and I've seen them in brushed alloy, red, blue, and black coated.
Thanks for any input, and I really hope we can put this together for those of us yet to find a front STB solution. BTW, I have no connection to this person, other than a potential and hopeful customer.
