Rear motor plate
 

What is the minimum thickness a rear engine plate should be?

Re: Rear motor plate
 

I use 0.090 steel and wouldn't go thinner....

Duce,

The two common mid plates are 1/4" aluminum and .090 steel.

"Generally" you see the 1/4" plate in dragsters and tube frame cars. "Generally" you see the .090" steel plate in back half door cars.

I do not recall seeing any other options.

With my super 10 build I have 1/4" aluminum front, 090" steel middle.

I do have 3/16" aluminum mid in my car with 1/4" front. Been running it for years. They are pretty narrow in my roadster though.

Just remember to tell your convertor guy how thick your mid plate is so that you have the correct mounting tabs for proper engagement!!!

Ed… .090 steel or .250 (T-6 6061) aluminum. MB.

I am using an Aluminum mid plate on my Comp Super Modified car.
Don't see any issue on using an Aluminum Mid Plate on a back-half car if you don't go too thin in the material.

Don't forget to use a (for, aft) engine limiter.....

Yes that's what I thought. I'm getting movement. Mine is .250 aluminum in front and .090 steel midplate.
