[QUOTE="bumplime, post: 15486854, member: 106761"] If this has been discussed to much I apologize, I couldn't find it. I am in the process of trying to decide whether to wait for a 2018 Mustang or go ahead with the 2017. If I wait, there always the next model year...which means I'm never getting back into a Mustang. Part of my research is on the gear ratios for this new model. I plan to purchase a GT Premium model without the Performance package. The car will be purchased with the Supercharger installed by the dealer. I will replace the Roush tune with one from Lund/VMP/Etc In my 2008 GT 500? The swap to 3.73s was very noticeable. Is this the same with the S550?i have seen some of the drag racers run the 3.55s, which surprises me. What kind of pros/cons are people experiencing first hand with the swap Of gears. My next thought, I plan to race the car at my local 1/4 mile drag strip. I will run drag radials. It is my understanding that the stock 1/2 shafts will hold for a while but they're the weak point. Are the Ford replacements as good as their competitors product? I have read about the shafts that are rated 800hp, 1200hp. I would rather have the right set in hand before breaking something and having the car down while I wait to fix it. [/QUOTE]
