Re: Which upgraded front swaybar?
In a hollow bar, I like a 1 1/8" OD X .156 wall. Hotchkis, Speed Tech have them. The Hellwig hollow version is 1 1/8" x .188" wall which is a bit stiffer for use with stock rate springs. All the hollow bars I know of are cold bent seamless tube and not heat treated, but they work fine. The Hellwig solid bars are Chrome Molly heat treated. I'd consider a 1" solid version close to the 1 1/8" hollow bars, maybe a bit softer. Some others are also hollow but I don't have info on them.
The Ride Tech bar has formed billet arms so it's more expensive to make. I dont' know the rate. It may mount further forward and have longer arms so needs to be thicker to achieve the same rate as the others. I'm not sure.
You can run a front bar only on the street but you will have some understeer. An adjustable rear bar is needed to get a perfect balance for autocross. If you consider a rear bar, get the rear bar from the same place as the front so you have a matched pair. If your rear tires are wider than the fronts, then you need a rear bar even more.
