I’ve had my GT4 since February now and it has been my daily driver ever since. I’ve put over 3k miles on the car and I’m excited to elaborate on what that experience has been like so far.
First off, let’s talk about the seats.
I have the fixed-back carbon bucket seats that are basically a clone of the 918 Spyder’s seats with GT4 embroidered in the headrest. It’s often recommended on the forums for GT3/4 owners to go with the Sport Plus seats instead. I think this is largely due to the adjustability available. The carbon buckets can only raise or lower and slide forward and back, there’s no tilt or bolster adjustment. This doesn’t phase me.
I find the seats to be super supportive. I am 5′ 11″ and 190lbs and the seats feel perfect to me. There’s a lot of lateral grip and even my shoulders feel especially well-supported. I’ve driven my GT4 on drives in excess of 100 miles in roughly 3 hours without any significant discomfort. I’m 26, so maybe my back is more resilient right now… but so far, so good.
The ride quality in the GT4 is actually pretty compliant. It’s not too harsh for a daily driver. The difference between the standard suspension mode and the more aggressive suspension mode is definitely noticeable, especially on a somewhat bumpy interstate. In some of my previous cars with adjustable suspension (Alfa Romeo Giulia Quadrifoglio, BMW M3) I have kept the suspension setting in the stiffest mode for maximum road feel but for 90% of my time in the GT4 I am driving with the suspension in the softer setting. It’s comfortable but still provides a lot of feedback.
I drive the car with the exhaust valve open 100% of the time. I like a loud car and the stock GT4 isn’t loud enough for me. It’s certainly not loud enough or throaty enough with the valve closed.
A GT4 definitely exposes you to more road noise than a non-GT Cayman but it’s very tolerable. I like it myself.
Storage space is an interesting topic for a Cayman, especially my GT4 with the BBI rollbar installed. I actually think the storage space for a 2-seater mid-engine car is pretty good. If I’m going to take my photo gear, I keep it in a 20L Peak Design Everyday backpack in the lower hatch area. I could easily fit the 30L variant and some detailing goodies or another backpack in that space as well.
Because I have a rollbar from BBI installed in the rear cabin space, the upper deck in the hatch is basically useless. I’ve thrown a Costco size bag of tortilla chips up there before, but using that deck 1) obstructs the view and 2) is useless with anything that you don’t want banging into a metal rollbar.
The frunk space is really great. We can do Costco grocery shopping for a household of two with enough food for 2-3 weeks only using the frunk. Don’t expect to fill the car with 12 months of toilet paper and you’ll be fine.
Truthfully, I rarely interact with the PCM (Porsche Communication Management) system. The speakers in the GT4 leave a lot to be desired. Seriously. They’re pretty awful. On the flip side, I’m listening to the engine behind my head more than I am my music. But… that doesn’t mean I want my speakers to sound like they’re the same setup in a base Nissan Juke.
I have the extended range fuel tank in my GT4 which allows me to fill the car up with 16.9 gallons of 91 octane fuel (Shell only). With a heavy foot, my daily driving mileage lands me about 310 miles per tank of fuel. It’s not great but for a naturally aspirated car like this, I’m content with the output.
Lastly, the gearbox.
I’ve owned 8 cars prior to the GT4 and 6/8 of them have been manuals. My two most recent cars prior to the GT4 were not, so I wondered if this might be a big adjustment. My M2 had a dual clutch transmission and my Quadrifoglio had a ZF8 speed, both driven exclusively in manual mode and shifted via paddles. I’m pleased to report that jumping back into a manual was an easy transition. I find the GT4 an easy manual car to daily drive. The clutch is a ton heavier than something like a Ford Focus RS, but that’s to be expected and after a day or two of driving, you don’t notice how much heavier it is in isolation. I drove an RS and kept stomping the floor. I got out of that car really missing the clutch feel in the GT4.
The shifter is excellent. Selecting a gear is really smooth and firm. It’s a joy for a daily driver. You always know where the gears are and it’s just a really enjoyable experience. When I’m driving around and not wanting to do a lot of footwork I engage Sport mode for the transmission – this causes the car to automatically rev-match my downshifts for me. I love the sound and the car executes the shifts flawlessly every single time. I can heel-toe downshift but there’s no human who can do it as perfectly as the car can do it on its own.
I am very happy with my GT4 as my daily driver. It’s my only car and the one that I drive over 99% of the time. I work from home so I don’t have a daily commute but I would not hesitate to take this car out if I did. I am already driving the car almost 7 days a week to run errands or for a spirited drive. My wife has a Focus hatchback that we can take if we really need the extra storage space. If you’re considering a GT4 but you need it to be a daily driver, I think you can pull it off. Throw some snow tires on it in the winter and you should be solid!
