Hey guys - I've been researching different options for the first mod to my new '09 GT. Contrary to what most people seem to do, I've settled on not getting a CAI/tune until later down the road (probably 2nd or 3rd mod). I've decided to go for a set of rear gears and driveshaft swap first. Figure the gear swap will require re-calibration of speedometer - this way I don't have to get a custom tune twice (once before gears and once after).
I think I'm set on the FRPP 3.73 gears (4.10s seemed like they might be a bit steep for a daily driver that sees a lot of highway mileage) and have seen a lot of recommendations to just have a Ford dealership put them in right the first time and hopefully reduce the chances of having to bring it back in for gear whine.
Figured since I'd be having the gears changed out, this would be a good opportunity to also swap in an aluminum (or other reliable light-weight) driveshaft. So far I've only checked out the Dynotech driveshaft - I was wondering if anyone else has had good/bad experiences with different driveshafts and/or any other thoughts/recommendations for a complete newbie like me??
Also, do you guys think swapping the stock S197 GT driveshaft with an aluminum driveshaft is something I could do in a driveway with 4 jack stands? I'm looking to do as much work on my own as I can with the tools I've got access to if only for the experience. I've heard changing the driveshaft isn't all that bad. On the other hand, I've read about nightmare experiences trying to change out the rear gears.
