I am planning on putting bigger tires in the rear of the car, so I decided to make some extended shackles to lift the car about 1″. I got some 1-1/2″ x 1/4″ flat steel and cut it into 4 10″ pieces. I drilled the first hole 3/4″ from the end, and the second hole 7″ from the first hole. I started with a pilot hole, then drilled to 3/8″, then drilled to the final 1/2″ hole.
Here you can see the difference between the stock shackle and the extended one.
I plan on making a second pair out of 2″ x 3/8″ steel just in case these start to bend.
And don’t worry, I ordered a set of bright yellow slapper traction bars to go with this…=D
