STX handling.. Whiteline 22mm?
 

Ok..

Car is 2013 BRZ, (no power mods as yet) with KW 2way clubsports, 17x9's 245/40 re71's and whiteline 22mm adj sway front sway bar.(at soft)

The car is awesome at hi speed autoX courses, but loses too much in the slower speed courses. (all asphalt)

I'd really like to keep that 22mm bar, and add a heavier bar in the rear.... but I am not sure that will cut it in the end. I run the oe bar in the rear atm, as this year is my first foray into STX I haven't yet got the cash together to finish the build (header, exh, tune etc)

Is anyone making that whiteline 22mm bar work or is it just too heavy a bar?

My current setup is Tein SRC’s, 10/12 springs, pretty much all the bushings, super pro 20 mm FSB, set full hard and stock tear with bushings. For me, everyone is different, the car is setup like a dream. Good turn in. The rear is not loose at all. I do have a super pro 18mm rear bar. But it makes the car way too loose for me.
For me to use the 18 mm RSB, I would have to go with the 22mm FSB. Again, for my taste and skills.
Try playing with shock settings. With the rear bar on I’d be almost full hard in the front and full soft in the rear.
That left me with too little room to adjust for different surfaces.
See is you can borrow someone’s spare. Try it.

I use a 22mm whiteline. Works fine on soft. Hard is too much rate. 6/7k rates and OE rear bar. Changing to the Perrin bar soon.

I tried the Whiteline 20mm front bar and 16mm rear bar with 5kg/5kg springs. I wasn't a fan of the balance, far too much understeer.

Well I think I don't have much to lose... likely going to go with the 18mm adj rear bar, and play with the shocks. AT this this point its either that or go back to OE in the front, may as well try replacing the rear.

60N/70N F/R springs? What's the alignment?

Could be a lot of things causing push, missing the mark on toe, camber, tire pressures, driver inputs, line choice, damper settings, etc. can make the car not do what you want it to do.

Hell my dad was convinced that his KW's were never going to ride comfortably, turned out he had compression and rebound flipped in his head and was adjusting the wrong one.

clubsports springs 340fr 400rr, alignment 0 toe front and rr, compression in the middle front and rear, rebound middle in the front, and 2 clicks stiffer than mid point in the rear. camber -3.6 frt, -2.6 rr

tire pressures at 30psi hot on all 4 corners, situation improved when i dropped to 28 front.
