Fabricating chassis braces
#19
Yeah that seems to be the believe. Fender braces are the ones that make a difference. I won’t be able to tell for sure since I made all of them and put them on at once. I tell you what, I’m sure the rest of these braces won’t hurt. I believe they will be of some help. As I said before, I could hear the chassis creaking when I installed and tightened up the bolts on the small under body ones. I’m sure it will help stiffen it up specially since one of them ties the chassis to subframe.

Here is a sneak peak at the brackets. Im waiting for paint to dry so i can install it on the car. I will post pictures. These pictures were taken as i was making them so in some of these they are very crude and still hadnt trimmed the brackets etc. Let me know what you guys think.

Thx man! Well, this is not what I do but if there’s enough interest I’ll make some extra sets as a side thing. Tell you what, they are sturdy as hell. They bolt up to 4 different places. I’m thinking of making a power brace next just for the hell of it but I don’t have a tube bender and well tired of the car sitting. Let’s see. Only thing that makes me want to do it is that I have the ets 4” ic which is too big for the braces they sell. I’d like to do it for the challenge of making it fit lol.

All right here are the pics of it installed. I jacked the car up and now it stays steady which is perfect. The front no longer moves so it proves these fender braces work. Im thinking of making a couple of sets. Maybe a white set and a black set to sell. Im thinking around $220 shipped with hardware and everything included. Let me know what you guys think and if anyone is interested.

Oh i tested it man. I looked at the same line that i posted earlier in the post and now with the braces installed it would not move. Im shocked as to how much the front was flexing before. Ill take pics tomorrow with the car jacked up. Thing with aluminum is that it has to be around 30% thicker than steel or so to be as strong (dont quote me on the numbers). Theres not alot of space inside those fenders to fit. I think for the fender braces the stronger the material the better. If titanium wasnt so expensive i would love to make a set out of that. What i like about these is that they tie into 4 points. The braces out there either tie into 3 points or im just not satisfied with the design. Example the nagisas are really cool but i wish there was an extra vertical bar in the back. I feel these need to have support on the back also (ex a triangle). Idk thats just me.

For sure. You know my Evom brothers will get a chance at them. Honestly guys I never thought there would be so much interest. I’m blown away. Lol. I liked them so much I figured I’d offer it to the evo guys and make some extra money. I’m doing this on the side so just remember not a big shop pumping these out like crazy. I will defenetly make a couple of batches. What sux is I haven’t made a jig so I will be using my car as a guinea pig for the first couple of batches lol. That means it will sit there looking sad with no fenders.

Engineering Info for you, Aluminum is basically 1/3 both weight and stiffness of Steel. Different varieties give different ultimate strength but stiffness is pretty well constant for all flavors.
In tention/compression, you only have a linear relationship between stiffness and area. So if you go 1/3rd lighter for aluminum, you'd need 3x the area for same stiffness and would then of course have the same weight.
The more interesting thing would be to find how minimally they can be made with either material since over building is just adding weight. Now that's a proper engineering problem.
