Tech Tips! - Evo 8/9

STM has always been meticulous when it comes to builds. Parts have to be lightweight, functional and look good! If you are making a mod list, we have a reference for what your stock parts weigh and where the best weight savings can be found.

This is also a great reference page for your stock fluid capacities to know how much oil you need to buy when you're changing your rear diff.

Our dyno and 1/4 mile tests were performed on the STM Mustang 500SE AWD with our 2005 Electric Blue Evolution VIII "Ricer."

Lighter is faster! Focusing your build on removing excess weight is an easy way to free up power. If you need any help deciding "What are the lightest parts for my Evo" just give us a call a to chat!

"Tech Tips" will continue to grow and we will be updating with torque specs and install how-to's soon!
