Re: Rear motor plate
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.

Re: Rear motor plate
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.

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

Re: Rear motor plate
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. |

Re: Rear motor plate

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