I sold my 991 rs for Targa 4 GTS due to the inconvenience driving the rs as DD. I'm planning to upgrade the coilover to Bilstein PSS10 and will love input from anyone with upgrade on their GTS coilover. Thanks!

I am also going to do coil overs on my 991.2 gt ,was thinking kw v3 or Bilstein clubsport. Not sure if kw v3 is an improvement on handling for spasm on my gts. Any feedback would be appreciated.

I used them at the track for one summer and adjusted the comp and rebound setttings endlessly to try to get the sweet spot, and on the smoothest sections of our old track the car was connected, but the slightest bump unsettled the car - due to the springs. The shock absorbers had little to do with what was happening because the springs didn’t let the suspension move much at all.
Driving on regular streets (admitting that the roads in my area are not well looked after) was literally a pain in the neck as every out of place pebble on the road sent shockwaves up your spine: the rear springs had no give in them at all. Like I said: the compression and rebound settings on the shocks were pointless since the rear springs allowed no movement anyway.
Maybe kw has redesigned them since I had them and/or maybe you are more tolerant of such a stiff ride so your results may vary. I swapped them out for Eibach springs and Bosch sports shocks and was (am) much happier.
YMMV.

edit:
Sorry for the bad link, it just took you to the vividracing homepage.
it was supposed to be a link to the Ohlins Road and Track coilovers...... anybody use those?

I had the Ohlins R&T for my 2015 M3 and those are wonderful coilover for street and track. I'm looking for a set of coilover too for my 2018 GTS. Me too are thinking about the B16 since it can retain the SPASM button. Still looking for more reviews on those

On the 997's it is a quite noticable improvement in handling on the track.
It would work with B16's also if you want a stiffer setup to begin with.

Understand the need for coil-overs in race cars.
Understood the need for coil-overs in older street cars.
Stopped understanding the "upgrade" around the time PASM showed up. Tested a very well set up 997 Turbo with GT3 arms, new ARBs, etc on stock PASM dampers with H&R springs and then the exact same car on $10,000 coil-overs set up by a big-name shop. The car was MUCH better on back roads with the PASM and H&R springs, and I was surprised to find that I preferred it that way on track, too.
So the upgrade might actually be a downgrade. Especially as PASM has only gotten better since the 997 era. My advice? Start with DSC and/or some H&R springs if you want to get the car a little lower and a little firmer. The beauty of PASM dampers is they adjust to deal with the oscillations as needed...and were set up by some of the best suspension people on earth.
EDIT: Just saw that you're in Taiwan. May I recommend calling Tom or Mike at TPC Racing in Maryland? I know it's a world away, but I've come across very few people who have a "knack" for great street cars that also do well with track work. Mike Levitas is one of them. It would be interesting to see what he says. I'm sure DSC will be part of his solution, but I'd be curious what else he would recommend. Nice call on the move from RS to GTS—should be a great car as a daily!
