I have an o6 evo 9 MR and am looking into getting a bigger rear sway bar. The car is lowered with Tanabe springs and has an H brace in the front. My question is what would be the best size sway bar to get?

 

Get both sway bars (front and rear).

Options are Swift, Robi, Whiteline, Cusco - to name a few.

Here is my review of the Swifts:

you don't want to get a big front sway bar at all if you get one at all will make it understeer even worse

 

it all really depends on your setup though

 

yeah but generally the evo understeers so adding a front sway would make it worse

 

yeah, but some people slap on the biggest thickest RSB they can find - in order to mask the car into rotating best. When in reality they are slowing their overall speed or tripod'ing.

It's all a balance. But like SmikeEvo said, there's a lot of options. I've used the Hotchkis 25mm adjustable RSB myself. I believe the stocker is 23mm. Aftermarket sizes range from 24 - 27mm I believe.

 

No it wont. Agree with other comments.
