3.73s are the way to go. While you are at it get some LCAs and an adjustable UCA to cure wheel hop issues. If your car is lowered, get the relo brackets for the lowers. Bye bye to wheel hop, and the car will be much easier to drive with the 3.73s.

I have a stock suspension, will just LCA's do the trick for the wheel hop?

LCAs will definitley help, and might cure all of it. If you lower the car, the relo brackets are needed to keep suspension geometry correct, and if lowered you will need the adj UCA to correct the driveshaft angle (pinion angle). If you haven't lowered the car, or dont plan to, then the LCAs might fix your wheel hop issues with no other modifications.

I keep hearing from people that the upper link is whats needed more than the LCA's but I don't know if that is true or not??

Why? Because with that much power and torque, Ford didn't need to throw lower gears on to make it faster (especially with standard launch control). That is how they can achieve a 3.5 second 0-60 as first gear reaches 60 at redline.

Depends on what you're trying to fix.

Wheel hop is mostly a (soft OE) bushing problem, so the path of least resistance here is to do the two lowers (they're much easier to get at and may solve the problem all by themselves). Followed by the UCA if the LCAs by themselves wasn't enough.

Anti-squat/initial launch bite is a different problem and is related to the rear suspension geometry. Here, you can go with either LCA relo brackets or a UCA that offers a choice of chassis-side mounting holes. The lower hole(s) will improve the anti-squat over the OE geometry. Note that you could do the aftermarket UCA bracket simultaneously with the UCA (and might as well do it once if you're fairly serious about drag racing - but stick to a single supplier of UCA and bracket if you do).

I'm betting on this being the reason - most magazines test 0-60 mph as well as the quarter mile, but don't report the 60-foot time.

Unless somebody here is the re-incarnation of Ronnie Sox, we aren't likely to ever hear of somebody getting their verified 0-60 mph time down into the mid-threes with a front-heavy RWD car on stock tires - if a shift is involved.

Also, when you are producing more than 500 ft lbs of torque at 1600 RPMs (600 ft lbs at 2500!), you don't need lower gears to get into the powerband! 4.10s would likely only slow you down...

Adjustable UCA did the trick for me on the wheel hop issue then I added LCA's. then Stedda springs and adjustable pan hard bar for a great lowered look and ride along with Adjustable struts, then came Front lower control arms. next was the 373 gears which stole 2 to 3 miles per gal on the highway. But made the car a lot more fun to drive in the city. Adding a little over 100 HP didn't hurt ether.
The list can go on and on. Everything you do to this car seems to add to the fun and smiles.

I changed to the Steeda LCA's on my 08 GT500 and the wheel hop stopped...all else under the car is stock except for a dyno-tech 1 piece DS
