Good how-to.

That's how I made mine. Copied Brians design for the weld on tabs for the control arm mounts and welded a bar straight between them.

Could you post more pics?

Specifically of the engine bay

Sure thing Rich. I still need to pull it back off and paint it, bare metal rusts with the quickness here in the north east. I made it with the cross tube short enough to fit a socket up on the inside bolt. I used 3/16 plate and traced out the control arm bucket over top, cut it out and welded it to the inside. I then bolted the mounts to the car, measured and cut my 1 1/2" square tube to 24 1/4", hammered it in and welded it in place. I also drilled and tapped the buckets for a zerk fitting so I can grease my delrin bushings on the car.

Flux core FTL. I need to set up an argon tank for my welder.

are those the stock Control arm buckets? also would it be worth while to turn this design into a K style support bar?

Turbo II Rotor · 10-08-2012, 06:31 PM

Yes, stock buckets. What do you plan on triangulating the bar to? Something like this?

I don't see much of a point if you have a strut tower bar as that will box the top of the suspension. I have the Mazdatrix one (seems like they don't make it anymore) which triangulates into the firewall and is very rigid. I haven't driven the car with the lower arm bar yet but I notice a difference when jacking the car up.

That's a cool idea right there

Yes... most definately...

is the car driveable? Planning on bringing it up to that auto-x deal if you attend? If you don't I could meet you that night in SW CT

Please tell me that you have jack stands under the car also not just the cinderblock shown in the picture. That is one of the worst things you could use and its in the weakest position also it doesn't take much to collapse a block that direction. The brace looks good I just want you to stick around long enough to use it.

Yeah they aren't the only thing keeping the car from crashing down.

Took some pics when I removed it from the car for paint.
