Personal lap time yes, but not to the last tenth or hundredth. I'm still too new to it and definitely don't have the time/effort ability to put towards really chasing something. What I was chasing is a little more fun with the turbo and now that it is in there, a little less "fun" with tail happy high speed activity.
In reality, the street **** or a spoiler is a half-measure. If you're searching for your PBs then you'll want a typical roof-level efficient wing. Also, don't forget about the front of the car! Air-dam is the easy button, but yes I know they're ugly as damnit. The biggest gain to have on NA/NB bumpers is to eliminate that "over-bite" the front bumper has. Getting that taken care of will make the rear aero setup work much better, but also it helps reduce overall lift, yes lift no downforce, on the front of the car.

One thing I noticed last year when playing with a GV-style lip is that it made a much larger difference in overall 'settled' feeling of the car when top was down vs up. I know you are asking about the rear, and while I have the 9LR street **** pictured here, I didn't notice a giant difference on the track with it; running with soft top up, NASA HPDE, N/A NA6.
