2015 rear sway bar only?

The 2015 suspension got tuned, less tail happy. Anyone tried to bring it back with a rear sway bar? How has that worked out for you?

Where was it confirmed it is less tail happy? Reports say it is more comfortable, I haven't see one that stated it is less neutral.

If the spring rates weren't changed, there's not much reason to change the sway bar.

Do you find the car pushes too much? Under what conditions?

"Underneath, the front suspension is stiffer and the rear shocks have been returned for "less body roll and a more communicative driving experience."

With the stiffer front you get more understeer, surely feels that way. If I turn in a corner too fast I get an almost understeer... I don't want to bother adjusting the suspensions I'd just get a rear sway bar. It may feel better with VSC off...

Sway bar is part of the suspension just fyi.
Just get camber bolts up front. Zero camber is bad for a sports car.

If you take a corner too fast in most cars you'll get understeer. They designed it that way on purpose, because the average user wouldn't know what to do if the rear end came around on them.

Like swarb said, a better alignment will do very nicely.

Where was that taken from? There's no quantitative confirmations that I've seen.

Mine understeers if you enter a corner too hot, almost every car out there will. Mine has swift sport springs (FRS rates), -2* camber all around, 0 front toe and 1/16" total rear toe. It rotates nicely with a proper corner entry speed, but it's also easy to get it pushing.

Have you driven a 2013 and 2015 back to back to see if it's actually the suspension changes doing what you're feeling?

What's your driving background? What conditions (auto x, track, backroads) are you getting the understeer?

You need to consult with KoolBRZ as he's the suspension guru around here.

Only for comfort, not for performance. After all, I wouldn't take my car on a track with 4k rear springs and no rear sway bar. The OP's post is really a performance question more appropriate for someone from CSG. I would send them here "http://www.ft86club.com/forums/showthread.php?t=45554" instead.
