If you're a new S650 Mustang owner looking to connect with other Mustang owners who love going to the track or autocrossing, you're in the right place. Be sure to create a vehicle profile for your Mustang here:

And use this forum to exchange ideas on setups, modifications, wheel/tire combos, maintenance, etc. This is your dedicated home. Enoy!

Jump on here as those of us who began at this Forum when it was BossMustangsOnline found as its continued to add more and more info for Trackrats, the data and help just grew and when many of us went to S550s we shared info as more and more of us put them through their paces. At first it was somewhat slim but then with the experiences and mods things became more apparent. So those of you with the new Horse, jump in and share your data whether you deem it really important or not as so many of us found that the little things often are the biggest for improvements. Remember, though, bigger and stickier tires and killer brake pads are the first two mods to help you go faster!
