I'm having a bit of trouble trying to understand your post. Were you trying to say "just so you know 19mm weather straight or like the 17mm is not stiffer."?

FYI, IS-F owners have been upgrading their original IS-F rear sway bar (17mm) to the F-Sport rear sway bar (19mm) for an even stiffer rear end and reduced understeer. Whether or not it would fit on a SC430 is a different story.

there is a metal bar in the center of the car that stops you from using a straight bar unless you do what Slvbullet did. otherwise you can't use the ISF-Sport Bar 19mm
the 17mm go's round this bar that's why it fits

So for those that didn't catch my post and pictures on this ...

Before Bacardi discovered the ISF OEM option folks used the TRD 32mm front sway bar from the older GS's. However the rear TRD 19mm sway bar was straight and wouldn't fit around the SC430 rear chassis support. I got tired of waiting and needed to balance the rear so I had the shop I work with modify the rear chassis support so the straight TRD sway would go through it. The job cost more than the rear TRD sway bar from Sewell but at the time I had no other option.

I also use the Cusco STB, Megan motor mounds and coil overs. I have been really happy with the handling at the track. Now my driving skills need to catch up ... More track time will help with that.

As Bacardi says, the 17mm rear is a great improvement and is close enough to match thenTRD fr 32mm if you have it already.

Yea I love the isf bar in my car. Who's end links did you use?

LexBrett

I actually feel more power getting to the wheels with the isf bar installed? Or is that just in my head?

Someone got the part number of the Sewell's rear sway bar ?

It's the sway bar kit with bushing and brackets that are under sc430 assecories. I think the kit is $136 with the CL discount but the bar alone is about $96. The brackets didn't fit on my car, but I did use the bushings.

Let me know if you have questions feel free to PM.

the brackets didn't fit because you have to do the Mod. to the brackets then they will fit. guys also use the Fig IS300 poly bushings.
just get the 2008 ISF sway bar and brackets

LexBrett

I tried. I couldn't get the14mm bolts off. And it was cold.

How do you like the is300 figs bushings? I can do that.

they are bushing to use. also do the bracket Mod. and your good the go.
lex
the Mod. should not be done on your back.

LexBrett

Paid to have it installed, no lift. Tail end feels more in control!

Yea it suck doing work on my back. Especially since I don't have a garage and my hoa freaks out when I work in front of my house. I end up doing work on the side of the highway outside my house on ramps. I don't mind most of the time, but I don't like yanking on tight suspension bolts. I also tried working in two local parks, but got kicked out of both and one park ranger even called the police

Maybe you could find a friend that will let you work in their driveway.

LexBrett

Yes I do sometimes..

So Fig's is gonna make rear sway bars at some point. He has an isf and he's gonna take the measurements with the hoop etc so it'll be available for the SC as well. Hopefully by next week he'll be done with measurements and I'll have his stock isf sway bar .
