Here are rates and sway bar sizing. Rates are for true coilover rear. I converted to lbs/in for easier reading.

GT4 EVO
Spring set N/mm (lbs/in):
F: 150(856)/170(970)/190(1084)
R: 130(742)/150(856)/170(970)

ARB:
F:26mm 3-way
R:22mm 3-way

Are you showing three different setups in the spring rates?

VERY interesting they use less rate in the rear. I might have been on to something this whole time… ;)

Correct. Car comes with 3 different sets of springs.

The rate stagger they run is slightly less than what I usually setup but they’re also on race tire with governed horsepower. If your rate stagger is not less the gt4 amount (100#) you’re on the right track. ;)

OK so sounds like I may run into same issue. I'll plan on maxing out what I can get with the stock struts/springs. Curious what you ended up with though.
I have a camber gauge I'll slap on there when I swap the track wheels back on.

I’m sure that mechanical diff doesn’t hurt either.

I currently run 50lb difference 650f/600r

The meats are on! The motorsports hardware studs were a bit sketchy to thread in. The lugs fealt like they wanted to cross thread.
yeah it seems like those studs are always like that.

helps a lot to clean them up with a die before installing them.

I wasn't happy with how they went in nor how the lug nuts threaded on. I brushed all the threads off.. but still.
My install was even less fun as one of the studs arrived with a bent thread. LOL. To Apex's credit, they had a new one to me immediately.

Curious what spacer and length of stud? The wheel looks quite wide for tire. Are those the 10.7 Titans?

I think it’s the angle and lense of the camera exaggerating it a bit there, but yea, Titans are 18x10.7 and those are 275/40/18 tires

same tire size on my 18x10.5 for reference

Hey there,

Anyone have feedback about using a Simpson hybrid-s device with the Supra? I'm 6'3 and already have to be very mindful when I climb in/out of the car with a helmet on. I've never owned a HANS device before, so I'm not sure how much it will limit my mobility getting in/out.

Cheers!

I use one with the stock seat and belt.
I'm 185cm (6'), so a bit shorter than you, and have no issues getting in or out.
