Chassis stiffness

Wait... Since when has a hybrid been a track car?! lol

 

Echo isnt a hybrid..Know your shit before you talk it..

 

lol They have a hybrid echo though...

 

ok..well maybe not, but the echo in stock form has terrible body roll and feel slike it woul dflip over if pushed to the limits..Now that that my suspension is totally done, She feels like shes on rails.

And if there is a hybrid echo ..It isnt in the states, and prolly has the weak ass 2nz-fe engine, Not the stroked and bord out 1nz-fe

On a side note..id def be interested in one of those if you fabbbed one up..
if thats possibble atleast.

 

I second the under body brace Jim if you make one. I'm definitely interested.

There was talk about Conrad_Turbo fabing up some under body braces for the 4th gen Alltrac (which would make it available for both Alltrac and FWD models) but I don't think anything ever came of it, or hasn't yet.

 

How many pasos are we talking for one? I would be really interested in one, the brace, I mean. PM me with some details, if you ever decide to actually go for something like this. It really would be nice to get a hold on something like this, for any celica owner! They are definitely flex riddled chassis! lol

 

That sucks... I haven't noticed how low my top actually goes... Mostly because it's only been down once, and I didn't look in the trunk... lol I don't plan on having the top down very often anyhow, as I have sensitive skin in the hot cali summers, (115 degrees here last summer, several days in a row! I had blisters!) and I get too cold in the winter... lol It would be kind of cool to be able to have one, that maybe I could just unbolt and move out of the way, or somehow have a quick release if I needed to remove it for some reason, though!

 

Build a better stock brace would only get you so far. I'm sure a lot of the benifit of that brace comes from the fact that it is mounted to the A-arm mounting point directly. And the increased spacing between these mounting points would also add to the rigidity of the chassis compared to the stock crossmember.

 

I hope you can use the support bar I took out. Damn was that a bitch. Gonna be comin in a big ass box.

 

Hey guys, one thing NASA is allowing us to do on our PT race cars is to seam weld the uni-body. No it's not going to be as much benefit to suspension stiffness as strut tower braces, but it will sure take most of the flex out of the chassis itself. This will be even more of a benefit to the hatchback cars, as the coupes are already much stiffer. If my still-born project ever gets rolling again, I plan on seam welding the entire chassis, then install an 8-point cage. The cage will tie the rear shock towers togather with a crossbrace between the rear hoop support, while the front will tie into the firewall for more rigid cabin support. I plan on either making the third member for the front shock towers, or simply buying a Cusco or Whiteline brace if still availble.

racerb :wink:

 

Jim you ever get that bar mounted to increase the stability of the car?

 

Yeah, I want to know what's up to. I'm really noticing the flex in my chassis, lately... My girl doesn't feel it when she drives, then again, she really doesn't care... WOMEN DON'T UNDERSTAND! lol I hit a good spot in the road the other day, that made the whole frame shutter... It wasn't bad enough to cause any steering issues, or anything, but it was bad enough that it scared the crap out of me... lol It's weird to have a whole car feel like it's twisting under your ass! I'm developing a bar, that might possibly work in the convertibles, but it's going to take a little time, as the welder I am using is a friends, and I can only use it on weekends, when he isn't busy! Wish I could TIG weld, it would be much cleaner, and the aluminum welds would be so much nicer... Oh well, steel bars work... I just need to remember, that I can't bend it to the way I need it...
