Just had an isf rear sway bar installed. I noticed an immediate difference in the rear in terms of reduced body roll, although there still is some.

I did not upgrade the sway bar links, which may be a factor, which I plan to do in the future. I also will be doing the front sway bars.

I tried to do it myself but failed to even budge the tight suspension bolts. And yes, I used a breaker bar but just couldn't get enough leverage (was under my car via ramps).

This is a nice low cost mod, and it will be interesting to see how the handling improves with the end links and front bar

Nice. I've been on the look out for a used isf sway bar..

LexBrett

There are isf sway bar kits (bar, bushings, and brackets) sold on Sewell Lexus for the sc430. Using the CL discount, I think the kits run about $140. Check it out. Even used you are probably not going to get better than that...

I would like to try this. Does any one know which year ISF are compatible with the SC? I have a 2002... Thanks!

Is the F-Sport rear sway bar an option for the SC430? It's a thicker bar (19mm vs 17mm) and it uses a straight bar design which would make it an even stiffer bar:

you can not use the ISF-Sport bar just get the 2008 ISF rear sway bar just so you know 17mm weather straight or like the 17mm is not stiffer. the only way you can use the 19mm is do what Slvbullet did. going from 12mm to 17mm makes a world of difference. I also use the GS 28.6 Front Bar.

Go to Sewell Lexus, search for sc430 assecories, and on the right will be a panel of options one of which is the sway bar upgrade (from the isf). If you don't see it feel free to PM

Hey Bacardi, do your posts address which front sway bar to use as well as end links ? I will check it out thanks

Thanks LexBrett, I wish they sold just the bar, from bacardi11's thread I see the stock sc430 brackets will fit and I do want to use the poly bushings from figs. Definitely an awesome price for a significant upgrade.


Awesome post bacardi11... thanks for the info.

remember you have to do the bracket mod. for the bracket to fit right like darthsid and myself did.
just get the bar and ISF brackets from swell's and the poly bushing from Fig Eng.
