I am seeing if anyone would like onothese made or for me t make a bunch and sell. I made a Custom B-pillar bar for my 323 last year I noticed a big difference! and now I have an mx3. Well I decided I needed one for my mx3, These are a direct bolt in to your seatbelt mounts, al you have to do is cut a bit out of your trim. so would anyone be interested in one of these for themselves??

depending on what the final product looked like i might be interested...and if the bar its self was round not rectangular it would be alot better, for looks and from seatbelt harnesses

They already make ones that mount to the rear shock towers, which doesn't force people out of the rear seats and is probably more stable.

yeah but I'm curious now if that would make a difference too... I don't have a backseat anyways

Depends, most people remove the rear belts instead of modifying the brackets to accomodate the bar...howeverthe rear strut bar would reinforce lateral twisting between the strut towers, this bar would help against body flex in the center of the vehicle, especially in the upper b-pillars where there is less support as opposed to lower in the body near the chassis/frame where the gains would be more likely minimal. This could be very useful for racing applications...an interesting idea would have one that is removable? Have static mounts, but the bar itself would be removable, by pins or bolts perhaps?

I already have a Tubular Rear strut tower bar...my next plan is to take that and your bar there and weld and weld them together ...in an open center X-brace...

I'll probably be adding a drop-down from the upper seatbelt mount to the floor and then bolt onto the rear seat mounts...because your still relying on body metal to prevent the upper section from flexing otherwise...

@ some point i'll be welding an X-Brace together from the upper rear strut towers to the center of the outer edges of the rear crossmember and bolting it in... which will make my rear end ROCK solid laterally..

I may be interested in one of these.
As mazdax3speed said, maybe a round style bar? but either way I like it.
What is the bar made out? and since installing in your mx3, how much of a difference have you noticed?
thanks!

I have to take a look at possible round bars, but this is just the prototype, and I notice a difference in on ramps and such where I can test it! ahah But I work at Mazda so I have alot of things availiable to me that I can use and test to see if things fit!

count me in! I'll take two! Just let me know a price and shipping to memphis,tn 38115... I think I would prefer a round version though for sure...

I would be interested in a round bar that was polished or gloss black, noone fits in the back anyways so I dont really care. I think that b pillar looks sharp.

Ohhh 1 more question! How thick should the round bar be for a harness?

well....literally SCHD 80 pipe or even 120...would be the best....almost no hole on the middle...

-Solid round-stock isn't actually as strong as pipe as far as flex goes...only under compression and tension..

a piece of 1" thick wall (atleast 1/8" wall) or better would be suitable..i'd try to find some 1"x1/4wall pipe though... that'd be stiff as concrete...
