I didn't know what section to post this in, so I gust put it in the general area.

I just picked up my new 2016 Scat Pack last night at CarMax. I was finally motivated to get a new Mopar from another thread over on FABO. The guy who started that picked up a new Mopar as well, a Challenger.

I was looking for about a month, and finally found one which was acceptable in color, interior, and powerplant. I was only willing to accept a 392, with the red interior, and either red or white exterior.

The car came with a new set of 245's and I can feel them breaking loose which is unacceptable. I am thinking on going with some smaller than 20" wheels in the rear so I can get a taller sidewall and a bigger patch when I air down to around 20 psi +/- for some drag radials.

On the subject of launching, one guy over on FABO touched upon how he swapped out his differential to a Getrag with 3.92 gearing. That is appealing, although after driving the Barracuda around on 4.10's, I may not go as steep as 3.92. It's hard to say though, since we have these sweet eight speed gearboxes, compared to my old TorqeFlite A727 only having three gears.

Here are a couple of pictures of the new ride.

The A8 has a 4.71 ratio in first gear. 4.71 x 3.92= 18.46. If you compare that to an old school 4 speed Mopar with a 4.10 rear ratio you would have 2.66 x 4.10= 10.906 in first gear. Your A8 with a 3.92 rear would be roughly equivalent to a 4 speed RoadRunner with a 6.94 rear ratio in first gear! Do the math. You think the tires are breaking loose easily now, you will have zero traction on the street with a 3.92 rear...but it will be fun. Maybe save a little extra money for replacement tires every couple months!

Congrats! I love the red interior as well. I’ll have to hold out for red on my next car. The 3.92 gear will work well on the street. I had a 6speed manual challenger with 3.92 rear gear and it was a blast to drive at all speeds. An old mopar 4 speed is a whole other animal.

Big Congrats on a beautiful car. Wider tires def. help with traction.
