With the CL discount from Sewell it's $94.39

 

this is one of the best upgrade for the 430sc

 

Great info! Thanks bacardi! If anyone chooses to take this mod on as a DIY, please post photos on how to do the change. Would really appreciate it!

 

One of guys from Japan said he had a rear 19mm on his car, said nice for the track changed back to the 17mm for the street. he is also using gs 28.6 front sway bar. I guess I get it right for the street. well balanced.

 

Very nice. Thanks for the info bacardi11 :-) The mod is on my list ;-)

 

Did you replace the brackets that hold the ISF bushings or did the stock ones work ok?

you must replace the bushing with the bar if bought new. I used the 430sc brackets
ebay for the JDM Lexus gs300 gs400 gs430 28.6mm front sway bar

 

What year of GS front you use ? Thank you !

 

ebay JDM lexus gs 300 GS 400 GS 430 front 28.6 perfect fit well balanced with the 2008 Stock ISF rear 17mm bar.
make sure you put the sway bar in correctly or you have a problem with your vsc/abs light in the dash.

 

So here is my question, if the stock ISF rear fits...then wouldnt the Fsport 2IS bar fit? We put on the 2IS fsport rear in the ISF world. So I would have to think they are both a match.

 

that would make since to me. one of the guys in Japan had the 19mm on his he though it was to much changed back to the 17mm

 

Thank you ! Bacardi11

 

I think the F sport bar is a different shape (straight) and won't fit the SC430.

 

yes I think your right its a straight bar. to go from stock 12mm to 17mm is a big difference. when you put the stock 12mm next to the 17mm you see it.

 

like I said JDM gs 28.6mm and the ISF 17mm this is the ISF setup from the factory. I like how the car handles now.
