Front strut tower bar, rear, or both....

[260DET]

What size anti-sway bars do you have at present? Unless my speed reading has failed, possible, there has been no mention of this. Facts, we need facts.

 

Anyway, 22mm front, 20mm rear (stock on my 260) are big enough providing they are poly bushed. Anything bigger than that will tend to bounce the car around. Back when you could get Z competition parts from Nissan the biggest front bar they sold was 23mm, which should tell us something.
