4.6 diff versus 4.3

[dom14]

I'm still running 4.3s with my 35's on my rb30.. Yeah, performance suffers a little, and the biggest downfall is probably downhill in low range first, it's still quite quick, fine for most thing but some of the steep downhill bits in the high country mean I'm clutching in and just letting the brakes inch me down... Fuel economy, I've gone up 1L/100km on 35's from 31's, so would take a while for me to recoup the cost of 4.6's, which are usually 1-2k depending on condition etc. For 32's, stick with the 4.3's.

Are you saying fuel economy improved when you went from 31" to 35"?
