Looks Like HPI Europe got the first shot at new upgrades for the E10. Images/text from HPI Europe:

E10 Sway Bar Set (#88016)
1.2mm, 1.4mm, 1.6mm
For a wide range of suspension tuning settings, you need to add the E10 Sway Bar Set to your ride! Designed to fit the E10 for maximum tuning options, you get 3 different thicknesses of swaybars plus all the mounting and adjustment hardware to fit them to your E10. These are the perfect match to the #88015 E10 Strut Brace Bar, giving you the tuning potential to hit the curves with style and grace! One set of sway bars will add sway bar functionality to one end of your E10.

E10 Strut Tower Bar Set (#88015)
Get a better-handling, more responsive car with this shock strut brace for the E10! Just like on a real car, the brace stiffens the suspension by eliminating flex at the tops of the shock towers. The result is you get a firmer, more nimble car with a minimum of effort! Included with the strut brace is installation hardware and a hex wrench key.

…and here I was about to ghetto it with some turnbuckles on my E10!
