Using the 25 degree shim with the standard 10 degree caster blocks will create an overall caster value of 35 degrees which will make the car a little less twitchy but may cause a little understeer.
It is most common to reduce the amount of caster when using a larger kick shim as more kick promotes weight transfer rearwards resulting in slightly more rear grip, a smaller caster block such as a 5 degree block is often used to compensate.
