Thinking about installing a rear gsr sway bar in my eg... got no front or rears currently... should I do this or am I wasting my time? I know its pretty thin... like 14mm only... but if I go with no front bar it should still work pretty well to reduce understeer i would think... anyone try doing this?

 

Yes, it will help, especially on EG's with no swaybar at all. Cheap upgrade

 

so how would this be different than say having a front and thicker rear sway as opposed to just having a modest gsr stock rear sway bar?

 

Less roll resistance all around with the larger bars up front and rear, but you could theoretically end up with the same "balance" by just putting on a smaller rear bar.

I say go for it, with no front bar it will keep the rear a bit flatter. Don't expect miracles though, those stock GSR bars ARE pretty wussy!
