Jesse: while you're waiting, I KNOW you'll be asking.

(Sorry, didn't follow the link, totally beat here.)
If it's got dogbones, MIP CVD's. This is a must, if you get nothing else (besides the failsafe) get these.
MIP 4-in-1 clutch
At least two spare spurs
When it comes to the GT, the Motorsaver is the perfect filter.
A 10-pack of flanged clutch bearings, and at least two new clutch nuts. Once the clutch nut starts to wear even just a little, the bushings/bearings will blow and you'll throw e-clips all the time.
Spare clutch e-clips.
Ofna throttle linkage. The plastic parts of the Ofna lnkage are a 10x improvement over that little aluminum pill thingy. This kit only comes with one rod, pick up a spare brake rod so you can install everything new.
Aluminum servo horns are awesome, or even the stock Ofna one is better than that piggy-back thing AE has goin' on.
89 oz/in steering, at least .15 or faster throttle, servos.
Wife and I love our GT's, beat 'em up again this weekend.
