It so much depends on a tire... And suspension, driving conditions, goals, etc. And I can bet my *** and two used Bridgestones that almost noone here will really be able to tell the difference of 2 lbs of pressure on a street car. I now I wouldn't be able to.
Eager to hear as well.
Excluding factory TPMS on our cars, when such was clearly available and cheap, despite Porsche's economic crap, was an unconscionable management decision.
It has saved my butt on a BMW's and others.
Porsche chose badly here.
I installed the Vesafe TPMS ($66 on Amazon) in another car, but here’s what it would look like in the 993. For track days, I’d definitely want it, especially with its low and high alarms. Main problem is that the cigarette lighter socket is always on, but I don’t know offhand how much current it draws.
How did they come out? Look a bit big in the video.
Sorry, I just finally got around to installing this.
Yeah, I'm not in love with the look exactly, so I took a black Sharpie to the logo on 'em to make it a little more discreet. I do like, however, that these lock on, so a teeny deterrent to anyone ever letting air out of your tires.
The app is good and pretty seamless and I'll see if I wind up liking this or if I go back to the old way of just checking my tires for air every time I got gasoline
A small datapoint. One of my other cars, an '09 Miata with under 50K miles, has factory TMPS. Apparently, a battery in one of them is dead and, apparently, the life of those sealed batteries is 8-10 years. So I have a privilege of spending $100 on 4 new aftermarket sensors or $300 on OEM sensors plus another $60+ on dismounting, remounting and re-balancing the tires. Did I mention I hate nannies? For now, I continue staring at a yellow dash warning light, reminding me of that fact.

These aren't sealed, come with batteries installed plus an extra set, aren't factory installed so no warning light and is completely passive using an iPhone app and Bluetooth, weighs 5 grams so probably don't need to re-balance any tires, easily reversible and if it breaks, this whole thing costs $150
I tried the Nonda TPMS and didn't like them, so I returned them. They seemed to be a big buggy, I couldn't get one of the four to work, the app didn't seem to fetch new data regularly, and they appeared a bit big on the wheels (and I had a small concern they might impact the wheel balance). They also looked goofy.
To top it off, with my impatience, I did some slight damage to my wheel when I removed the anti-theft nut with the little tool that's included.
Oh well, I hope others have better luck. Still searching for a solution.

I meant to bitch about the stock TPMS Which are required on all cars in US since 2009, I believe.
