I actually find the Yaris needs more help with accelerating out of corners at the track. The front lifts and starts to understeer a lot if I accelerate too early, and I’ve been hoping these bushes would resolve that. Based on that I’m surprised you went for the brake improvement rather than the acceleration improvement.
P.S. RIP to the RB26 hiding in the back shelf.

Jason, let’s see. Not tracked the Yaris yet, so went for braking stability first. May switch to lift reduction later..

@@heelntoe1904 fair enough see how you go. I also picked up that the tab on the camber bolt was facing the wheel, not sure if it was left that way but if you face it inwards your can achieve 3 degrees on the stock shocks and springs. I’m running just shy of 3 degrees and have 6 degrees castor, very similar to you and the car is majorly improved from that alone. I also run 2mm toe out front and 4mm toe out rear and that has to be the single biggest improvement I’ve done (mostly the rear toe out). Keep us informed on your progress :) subscribed!

The way he put the bushes improves on what you're describing. On the istructions they talk about stability, because the bushing adds or lowers the amount of kick-up. He put the gold bushing under the arm so it reduces kick-up so there's less up and down movement during braking and acclereration=less weight trasfer front to back, adding stability under braking and reducing understeer on corner exit.

Nice explanation here. I've just put the Whiteline front camber bolts and the PowerFlex rear camber bolts. Haven't taken it to the suspension shop yet for the adjustments.

Worth it

@@heelntoe1904 I'll work with my suspension guy, try to get your settings or bit more camber if I can.
How does it feel with 1mm toe out front and 1mm toe in rear?

[@heelntoe1904]

Fine for me. Think it's the combination of caster kit and bolts that work well.

[@AmjadJDM]

May have missed it, but did you fit rear camber bolts?

[@heelntoe1904]

No

Thanks for the video. Just subbed to your channel. I have the same bits for my GR Yaris not yet installed. Hope you will do a follow up vid on your findings. I passed on the link to the GR Yaris Australia Facebook group, you might pick up some more subs from down under! Cheers!
