FlexCup for Universal Classic Car Cup Holder
The bare cup-holder ring takes one drink at a time, and only if it is the right size. A slim espresso cup rattles low. A wide tumbler perches on the rim. A can skates the moment the road turns. The FlexCup drops into the 3-inch ring and becomes a flexible pocket that grips the drinks the open ring can't hold on its own — espresso cups to oversized tumblers, cans, water bottles. Push it in when you want the extra hold. Lift it out when you don't.

Not sure it fits your holder?
Tell us your top-plate size before you order and we will confirm the fit — a real answer within a day, free. A change-of-mind return costs you return shipping plus a 25% restocking fee, so it is cheaper to ask than to guess. If it arrives defective or wrong, we replace or refund it free.
The problem it solves
The open ring holds one drink. It doesn't hold every drink.
The cup-holder ring is a fixed opening. A standard takeaway coffee fits it well. A slim espresso cup sits too low and rattles, a wide Yeti-class tumbler perches on the rim, and a can slides free the moment you take a corner with any pace.
The FlexCup is a flexible pocket that seats into the 3-inch ring and closes the gap around whatever you are carrying. The material hugs the cup and holds it down — over cobbles, across a level crossing, through a fast B-road in a 993.
A drink that stays seated is a drink that never ends up on the leather.
In when you want it, out when you don't
One ring, set up two ways
Carrying an espresso or a can today? Drop the FlexCup in for the extra grip. Want the full opening back for a wide tumbler that needs the bare ring? Lift it out. It seats and releases by hand — no tools, no hardware, nothing to unbolt, nothing left behind.
With no drink aboard, the pocket earns its place a second way: keys, sunglasses, and the coins that otherwise migrate under the seat sit in it instead of the footwell.
You set it up around your drink and your drive — not the other way round.
Before you order
It fits the 3-inch top plate. Only the 3-inch.
The FlexCup is sized to seat in the 3-inch top plate of the Rinashi cup holder. It does not fit the 3.5-inch or the 4-inch plate — the opening has to be 3 inches for the pocket to grip correctly. Check the plate on your holder before you add it.
The pocket is a single flexible moulding with a rounded front tab. It flexes to the cup, grips on rough roads, and lifts out clean without marking the plate. Running a 3.5 or a 4? Size a 3-inch plate to your car first, then the FlexCup drops straight in.
For off-road use only.

Running a 3.5 or 4-inch plate?
The plate sets the opening. Keep it at 3 inches.
The FlexCup only seats in the 3-inch opening. The top plate is the part that sets that size — the 3-inch takes cans, coffee, and most water bottles up to 2.9 inches wide, and it is the only plate the FlexCup fits. If your holder runs a 3.5 or a 4, add a 3-inch plate and the pocket drops straight in.
Before you add it
Will it fit your holder?
Is the FlexCup a second drink holder?
No. The FlexCup is a flexible pocket for keys, sunglasses, gum — the small stuff that otherwise rolls around the footwell. It is not built to carry bottle weight; the top plates do that. It fits the 3" top plate only.
Which top-plate size fits my bottle?
Measure your bottle at its widest point. The 3" opening fits up to ø2.9" — cans, coffee cups, most water bottles. The 3½" fits up to ø3.4" — the 18 oz Yeti class. The 4" fits up to ø3.9" — large tumblers. By design the bottle rests on the car's floor: the plate steadies it, the floor carries the weight.
