Rocker Reinforcement - What are your thoughts?
October 22, 2009 10:38AM
I've heard of more than a few people reinforcing the bottom of their rockers. I've heard of people welding angle iron, square tube, tube frames (Matt Iorio), etc...

I like the idea. I have lots of hours of recreational off-road driving experience and the sound of crushing rockers is burned into my ears. My spare shell/parts car was the old 99 Car/Course Closing Car and It's rockers are crushed!

I'd like to know what others have done. And, more importantly, how did it hold up to stage abuse?

I've held some angle iron up to the pinch seam. Unless it's huge - like 1 1/4" or 1 1/2", its only going to touch the rocker on one side of the seam. I don't want to add unnecessary wieght so I'm looking for ther ideas.

I was thinking about getting some 1" square tube, taking the angle grinder to it with a 1/4" grinding wheel and cutting a slit in the middle of one of the faces, down the length of the tube. I'd slide the pinch seam into the gap and weld the tube to the rockers... Thoughts?

I welded a 1" sqaure tube to the pinch seam. I added a couple of little plates to tie it to the floor boards as well.

The pinchseam on my car is perfect, not squashed, the rocker sheet metal itself has a couple of dents, but it's just sheet metal.

The only problem with this..is if the car EVER needs to go on frame straightener...you are in trouble.

I did something almost identical to this on a Cherokee I had. Scaled down to car size it might be appropriate. Great if you have rusty rockers you want to cut out anyway.

We simply rivet UHMW along the rockers to keep the metal in decent shape.

On the 510 we had to fabricate new rockers, but it turned out to be pretty easy job.

On the Integra we took a pretty good hit, but it ended up being mostly covered up by the side skirts and no harm really done.

I'm with Dave.

I never beefed them up, but i caved them in a bit on the last two cars (Sentra, Impreza) The jacking points (unless you do pin jacks) get hammered on a rally car and rocks get 'em too.

I hate to add weight or labor to a car, but I might set up the next car for pin jacks, if it's Asian.

Our SAAB 96 had rotten rockers. We cut them off and used 3x3 square tubing for a rocker mated to the cage. We added a cosmetic quarter-round of sheetmetal.

Jason,

I'm building a 96. You got any pictures to share?

I went with 1"x1" square tubing, 1/8 thick. I cut a strip out and profiled it to fit.

It added 14 lbs in total.

I like!

(I will most likely add a 'ramp' to the front to act as a skid plate.)

Good thing you have the pin stands. My dad has something sorta similar on his cone squishing car (why, I'm not sure), and if you don't put it on the stands just right, interesting things happen to whatever is downhill from the car.

hehehe

it took up floor space... I replaced it with a 8x8 chunk of wood. I was using it to lift the scissor jack that held the tubes while I welded.

I have angle iron on my rockers. It reinforces them, makes it easy to place the jackstands at service, and provides the outer mounts for my underbody protection.

My calculated net weight gain from that is about 8 lbs.
