what rear sway bar to my mods???

400RWHP M6 TA

I was wondering what rear sway bar will be the best for my setup. I was thinking about 25mm Solid ST sway bar, but some say its overkill. I need good road course setup...
Thanks

I would go with a 24/25mm, but that is me. Might have a little steering problem, but most likely nothing too huge or too noticeable.

I make a Hollow 22 expressly for that purpose.
