    2005-2010 Mustang GT Tech
    Here is my solution for this problem. The car would sputter violently when pressing hard on the gas pedal or when driving on a steep uphill.

    2005-2010 Mustang GT Tech
    I am looking to replace the clutch in my car in the next 1k-5k miles. It is a 08 Bullitt, with the added power and 3.73 gears over the gt (I know not a lot). Here is the question.

    Hi all, I have a Mustang GT, 4.6 L engine, produced in 2010. I noticed that the rear end slides right on hard acceleration. Clearly, it happens on slippery surfaces (snow, ice or wet), but I believe to feel the same tendency on dry surfaces as well. Is it from the extra wight of the...
