What diff ratio would be recommended in a standard enough 180sx with a fmic, full 3" exhaust for a track like tynagh in galway?

Well itl b second gear mostly so u don't want anthin too close ul b on the limiter all day ! I'd say a 3.9 would b grand that's what I'm using !

You will give it 3rd coming off some corners hard. Dunno what ratio is in mine though.

Prob a 3:7 or 3:9 anyway should be grand

[alan opel]

As long as its not like a 4.4 you'll b grand!!
