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.

The cover is held in by 4 plastic push connectors.

Remove the 7 small screws (flat-head Philips) indicated by the yellow arrows.
Step 8: Gently lift cover

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.
Flip the whole thing over and remove the front plastic part gently.
Step 10: Free the rear section

Don't mix them up!Â

Step 14: Remove plastic ring and flaps
Do this for all four cupholders.
Step 15: Saw
Cut carefully so that you only remove the bottom part of the cupholder.
Step 16: Bottoms removed
You may choose to only remove some of them, and leave some as they were.
Step 18: Stopping point 1
Put everything back together, and enjoy your no-spill cupholders.
However, if you like the occasional iced tea or bottled water, read on.
Step 19: Straps, 60 degree
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.
Step 20: Install 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.
Step 21: Snap plastic ring down
When the plastic cupholder is attached to the metal tray, everything is held even more tightly.
