Can someone measure their rear swaybar diameter in mm for me please? Looking for this general info but cant find it. Thanks!

 

Back in the day, when I was doing research on the ISX50, ISF, and FSport bars I went to a dealer and crawled under a bunch of cars with a micrometer and measured them. I don't know the RCF rear sway diameter, but would be interested in knowing.

I'm surprised no after market sways are available. Adjustable sways could have as much impact on handling as much as springs

 

stiffer sways need stiffer springs. not many stiff suspension available .

 

I agree. My old G35 had coilovers and sways and I found the best setting was medium on the sways and softer dampening on the rear coilovers.

 

You all are confusing spring rate with damping force. Springs don't make the suspension "stiff" the damping required to control higher rate springs makes the suspension stiff.

Swaybars are a band aid for soft springs. The progressively eliminate the independence of your independent suspension and should be the last place you look to improve handling. Everything starts with picking the spring rate that is right for your driving. There is nothing more important in basic chassis setup than spring selection.

 

Sounds like you failed to click the link to Far North Racing. They're only national autocross champions. What would they know about chassis setup and tuning?

 

^^^^Yep, I disagree also, but that's another story. I put an FSport rear bar on my ISF with GREAT results. That change along with the RRRacing USRS and wider RCF wheels and wider tires (255 & 295) has dramatically improved the handling of my ISF.

BUT, can we cease all this arguing and get back on topic. I would really be interested in knowing the sway bar (Front & Rear) dimensions of the RCF. Can someone please get a mic, crawl under their RCF or GSF (yes Lance - YOU) and report here?
