FS steel plate ballast weight - cut to fit footwell
 

Each plate is 1” thick and about 80 lbs and there’s two. This is a great way to put the weight where you want it. They’re cut to fit in the footwell and then bolt to the floor. One 2’x2’ 1” piece of steel is over $400 right now, so $300 for the pair is cheap! I can facilitate shipping.https://cimg1.ibsrv.net/gimg/rennlis...b905baefe.jpeg

You might want to specify what car's footwell.

I'd say 993/964 by the shape of it. His avatar is also a hint.

Bump, for some ballast, 993, 964 or other.
