Frame Rail Reinforcement

Postby k.beaty » Wed Oct 30, 2013 5:34 pm

Has anyone tried reinforcing their frame rails. It should make a huge difference in chassis stiffening, as well as provide a solid jacking point. I've found these frame rail braces for Mazda Miata's and am thinking about fitting them to my Celica. It can't be that much different. I've searched and it seems like no one has done anything like this for anything other than a Miata.

I think Ultra Racing makes some chassis braces kind of like that for our cars, but I've never heard from anyone using them.

Mafix, I like it. I was just thinking this would be easily done with a welder and some steel. Did you do any cross bracing? I couldn't tell from the picture.

If someone has measurments for Celica frame rails, i can try to get the measuerment for a miata; guess i could do both since they are parked next to each other.
Miatas have a lot of extra (aftermarket) bracing available due to the soft top design, worth looking into/ go through that catalog to see what else can be done.

The only thing I don't like about the Ultra Racing braces is that it looks like you sacrifice a ton of ground clearance with them.

I found all the measurements for the Flyin' Miata braces online. I just have to crawl under my car and do some measuring.

no need for cross braces with a roll cage.

I fabricate3d these up from 3" x 1" steel tubing. then welded them full length inside of the pinch weld, fire wall, and trailing arm boxes.
