Nice 10T
The kyosho shocks are just as good if in good shape if not better than the original AE's (yes, I'm gonna get flamed for that

) So I wouldn't swap them unless you are desperately willing to go back to stock configuration. As Todd mentionned though, for bashing on the driveway, you want to disassemble them and limit their upward travel by placing washers under the piston inside the shock, so that your car doesn't float around too much. So go internal shims and stiffer springs as mentioned by Todd, rather than changing to AE shocks which will require the same internal shims and stiffer springs anyway.
I don't want to sound like a naysayer but I think a 5700kv castle combo is too much motor for a 10T basher... It will be
fast, meaning if you touch something you are more likely to break parts, which is never a good thing on a vintage car with a scarce parts supply. The transmission will withstand it if setup right, but if you are not so versed into building ball diffs the "right" way, you have a much higher likelihood of havings things go wrong. The B4 topshaft suggestion above allows you to use a multi disc slipper, not necessarily a VTS - compared to the single disc slipper that was stock and worked very well on the stealth transmission in the 90's, but again with motors somewhat milder than a 5700kv brushless. The diff will still see an immense amount of stress and require regular rebuilds. So, stepping down a bit motor-wise could also save you some bucks in transmission upgrade/maintenance. I'm not even getting into tire wear
Keep in mind that although being the best car of the 80's/90's, this is still a car that was designed in that era, where 5700kv brushless did not exist, and only the top guns could run top-of-the line motors that barely came close to this. And these guys had a lot of time to do RC, and a lot of maintenance time and budget was spend doing so...
Will you run this Onyx NiMH pack? at least this would nicely limit the performance of the 5700kv
