[QUOTE="93 347 Cobra, post: 14849429, member: 7047"] Back at ya. I think these cars are pretty close to perfect from the factory. They just need gears, res delete, and throttle body (only because it picks up insane power for such a straightforward bolt-on). Some guys who have made hard launches at the strip or street on drag radials have gotten noticeable whine. Early on mine are almost silent. I put on another 15 miles earlier this morning and the car just puts a smile on my face. It was in the low 50s this morning and on stock F1s traction was already a major issue but is much more so now. The tires don't let go so quickly but more easily if that makes any sense. I expect the ass-end to slide around a bit in colder temps so it was no big deal. I haven't gone WOT in 1st and won't do so until I drive it for another few hundred miles. I ran the car to about 120 from 60 and on the 3 to 4 shift around 110 the ass-end twitched. I need some better tires or warmer temps so these F1s actually grip. A few other items to note: 1) I did not need the side bearings replaced as they were in excellent shape with only 12.8k on the clock so the OE part number installation kit I ordered was perfect for the task 2) As has been stated before by others the OE part number gears are EXACTLY the same as FRPP gears, same markings and everything 3) As stated by others in a few posts on previous threads Motive did indeed make the gears in some of the FRPP gears from a few years ago that are not as high quality as the Ford gears (shop owner verified this) [/QUOTE]
