It is possible to modify the stock cupholders to make them less prone to spill.
This instructable gives you step-by-step instructions on how to do it.
Please note that this modification is designed to accommodate medium sized cups (16 - 20 oz) with tapered sides, and straight sided 12 - 16 oz bottles. It does not work well with small cups. You need to determine for yourself whether thhis modification will meet your beverage needs.

Step 9: Remove 2 Screws
This makes a total of 9 screws removed so far.
The front plastic part of the cupholder assembly will now come apart from the metal tray.
The rear plastic part of the cupholder is still attached.

Put everything back together, and enjoy your no-spill cupholders.
However, if you like the occasional iced tea or bottled water, read on.

Sew them together in the middle at about a 60 degree angle.
Fold over each end and sew it to make the end fatter than the webbing.

Push the ring down until it snaps into place.
You should be able to slide the nylon webbing to make some last minute adjustments.
