What can i do to make the cars suspension feel more sporty?

 

Set it to PASM sport or sport plus.

 

sport plus mode is pretty darn firm for a 4000+ pound street car?

 

I agree, plus the chassis is so good "feels soft" is probably a complement considering how well it handles. Not sure what the OP is trying to achieve but in my experience HARD suspension does not equal GOOD handling. My PTT (with PDCC) in Sport Plus feels hard (hard damping, firm rebound, no bounce) and handles superbly.

 

Yes, +1. The car handles very well for it's size-especially with PDCC, PTV and sport chrono for sport plus mode.

 

Wow...unless the PTT has a way different suspension from the GTS (I am a newbie, but I thought they were the same), I cannot imagine wanting the suspension any tighter than it is stock. I personally LOVE a very tight car, but on SportsPlus mode, the car can be downright jarring on less than perfect roads. Stupid question, but are you sure that your tire pressures are adjust properly? I have mine (on the 20's) at 41 cold all the way around, and man, this car is rock solid and planted.

 

the GTS has a different setting - turbo's are softer. most reveiws find the GTS settings to be the best for the car by really making it sportier but not losing the GT part of the GTS
