This is a stage 3 (6-speed) with all the supporting mods - fuel pump, injectors, FMIC, exhaust etc. It is tuned for 93 octane at 25psi. It comes with Stasis coilovers and has excellent street manners. The interior was swapped out and converted - door cards, console, rear seats, climate control and upgraded Audi B8-S4 front seats with working controls and seat heaters. The car is tinted with Llumar CTX (ceramic) 35%. Paint and body are in great condition - no filter on the pics. Everything works - cold ac, hot heater, heated seats, stereo with upgraded speakers etc. The car runs strong, fast, and handles even better in all driving conditions.
