You can drop it which is cool. I never understood your point of contention. You even refer me to some other members post but as far as I can tell, i agree with him and vice versa. He even like my original post that seemed to bother you.

It is 1mm larger, but the rear spring rates are softer.

It's actually 2mm larger. 16mm in MY17+ and 14mm on earlier cars.

EDIT: Correction, the MY17 rear bar is 15mm as stated. Not 16mm.

Are you certain?

2008 2.5WRX, 2017 brz 15mm pn: 2045FG002
2017 Toyota 86 rear is 15mm pn: SU00306461

2008 is the only year where the wrx had 15mm. 2009 the wrx went to 16mm with different pn

Would 16mm work. Yes. But is it OEM MY17+ Spec, I don’t think so.

Rear spring Softer compare to ? Brz or FRS?

Based on my research, it’s probably harder than MY13 BRZ, but softer than MY13 FRS

You are most likely understeering from the lack of camber in the front, until that’s fixed you really need to be entering corners slower and focusing more on your corner exit. Once you add the camber you may discover you need a slightly stiffer front spring rate (or sway bar rate) to reinforce the added camber.

I’d personally go with RCE springs (truly the best) and put the idea of sway bars out of your head until you think you need to change the balance of the car at the maximum level. Sway bar upgrades are awesome on certain cars, like it was adding an rs4 rear bar to my Audi a4. On this car, it’ll just make it stiffer which you should’ve just done with spring rates.

I'll have my 86 on the lift this weekend, I'll check the front and rear sway bar with a caliper.

Pretty certain. I have both bars at home off the car, I'll measure them tonight.

I know the PP on the 17 Yellow has a 1mm larger rear sway bar. Not sure if it is included on the non PP?

Nope, I'm wrong. The 2017 rear bar is 15mm as shown per the part #. Wonder why I had it confused...

I like my adjustable Hotchkis bars.
