Id remove and touch nothing. Just do one thing at a time.

Go none, or try to find a buddy with a G35 that will swap rear bars.

I have a similar question I guess, since SCCA Street class rules only allow 1 sway bar change. So which will be faster (assuming car only has koni yellows)?

hotchkis front bar with oem rear bar?

or

Oem front bar with no rear bar?

I would keep your stock rear and run the hotchkis front..

I know our cars like a stiff front bar..

I would be using the stock rear with the Hotchkis front but I didn't keep the stock rear.

I think the old SCCA stock class hot setup was the Hotchkis front bar with oem rear bar with a lot of Hoosier squeezed on the front tires. With street class with 200tw street tires I don't know if the same setup is used. I would try to cram the 275/35/19 RE-71R on the front with the Hotchkis front bar and see how it worked.

I am using whiteline and though I don't autocross as much anymore, when I do it is PLENTY of bar. I felt no need for anything stiffer, and I think stiffer would just promote a push. That said, if you end up on race tires, that would probably change...
