Hello i am thinking about purchasing this roush phase 1 kit. To be able to use this kit, would i need to upgrade any other parts in my 2015 stock base model GT? Such as drive shaft, clutch, etc..? Can i have a list of all parts that need to be upgraded?

Asked by: Chance0012
Depending on the type of driving you plan on doing depends on the parts you may want to upgrade. If you plan on doing any type of track racing upgrading the axles, driveshaft and clutch would be a good idea.
