Hey all! 2019 GT PP
I’m looking to upgrade my swaybars finally and just would like some input as what could be the best combo for my setup.
FRPP Track Dampeners
BMR Handling Springs (250front/980rear)
Was thinking about going BMR front(middle setting)
GT350R rear bar
Would this be too much for a daily/occasional track car or is this the right combo of should I keep the rear PP bar? Any insight would be appreciated, also should I get rear adjustable end links along with the fronts or just the fronts?
Thanks!

If I googled the right spring, the BMR fronts are 300lbs which will give you more front roll couple (more understeer) You would not need so much front ARB. If you raise your rear spring rate any then you would want to tune the new OS/US balance with a stiffer front bar. The PP bar is probably fine for dual use street/track.

Thanks for the info! the revised ones are actually 250/980, I will edit my post to include that!

Don't be so confident about that balance shift. You're only looking at 1 part of the equation. Roll couple distribution matters, but it's not some single definitive variable. It's just one of the spices in the soup.

RC is an acceptable approximation, front roll couple bias means understeer... rear bias means oversteer. There is nothing wrong with targeting a RC distribution for a baseline use. At no point did I use RC as a definitive "must be"
