Bought my 2010 speed3 with 15k and immediately did full intake, access port and test pipe, and a hpfp which is the weak link from the factory, followed by an etune. and have been running 22lbs with no issues for appx. 25k now!
On stock suspension is handles great and rides good. It has great manners on the freeway at speed and does well in traffic under 50mph. Stock brakes are nice and have great initial bite and no fade even under heavy braking. If you want to drive a modded version before purchase or to help sway you either direction pm me.
