Budget Spring Spacer
Racing in a divison where weight jacks and adjustable spring spacers aren't allowed? You have to get a little creative. I use water pump pulleys. They fit the spring bucket in the chassis nicely and the recess keeps them centered in the spring. A serpentine or six-rib pulley is equivalent to a 1-inch spacer and a "V" belt pulley is about 1/2-inch. You can also weld them together for spacers thicker than 1 inch.

Temp Adjustment
Here is my tech tip for a chance at a jacket. I use different length fan spacers to change the temp on our motors, both open and Spec. Each spacer I have is 1 inch longer or shorter and that changes the temperature approximately 10 degrees. I start close to the radiator and then back away. The spacers I have use flush allen bolts to mount to the water pump and then small bolts that hold the fan so it is easy to change and I don't lose the alignment of the pulley.
