Hey I just got my P5 back in April, I love the car but was wondering what are some possible inexpensive mods to the engine/drivetrain that can be done(preferably within the warranty) being that I am new to all this and really could not do it myself.
Thanks

 

Check out my sig at the bottom. All those mods are simple bolt on jobs and they should not run more than $1000 with the exception of the rims and tires.
