Has anybody used this on their 55-57 car?

https://www.summitracing.com/parts/sum-770810?seid ...

If so, any noticeable improvement?

What other suspension and/or steering changes did you do along with it?

Thanks for any feedback, positive or negative.

Stay safe everyone!!

Looks like a waste of $800 and whatever time it takes to install it. IMO.

I agree, twisting of the frame corner to corner is a weak point of the tri-5 frame, with no heavy cross members except the front. A sturdy transmission mount and shock bar will be more effective to keep the frame from twisting. The sheet metal between the rails will do little to prevent twist.

I agree with acardon. The stock tri 5 frame is weak from corner to corner. It flexes considerably. So if you're in the market to stiffen up the frame, consider doing work inside the frame rails that connects one side to the other.

Case in point: The Nomad frame I had Chevynut build for me. He takes a stock frame and adds Art Morrison inner frame pieces (and also adds Corvette C4 suspension mounting points from and rear).

As I review the pics from the Summit website, I don't see much there at stiffens it from side to side. Just bolt on parts.

Here's a pic of the AME frame stiffening. Maybe you call them and inquire if you can buy ONLY these pieces and weld it up yourself.

AME does offer an X brace/crossmember kit to retrofit stock frames.

Two things about the Summit kit and similar offerings. One, lack of a substantial crossmember. Two, those bent tubes aren't all that stiff - they just bend when loaded and this doesn't transfer to the main rails. Contrast that to the AME style where loads are transferred through the X members in a straight line.

Thanks for the input!!

With the current situation, I find myself watching a bunch of you-tube videos of fellows working on and modifying their 57's and stumbled across the one by Summit showing it being installed.

Was just wondering if there were any real world experiences with this and what the results were.

I do like the looks of the Art Morrison piece and they are just a little over an hours drive for me, so maybe when things calm down I can make a road trip up.

Thanks again!

How do you get the trans out to change the clutch??

That short trans mount you see in the pic has tabs that allow bolts to mount to each side of the frame. You can't see those in the pic though.

Drop those 2 bolts and drop the mount and the trans comes back and down. No prob.

I can personally confirm that. Last month Paul and I had the Nomad on my lift and using a transmission jack we pulled his Tranny back to install a new bearing and all in all it was no problem at all.
