4.11s in my new VL, but I don't think it's all that bad for sitting on 100, as just moved on from an STi, and that would sit on ~3250 on the highway...

3.9's suit the rb25 box perfectly as its the stock final drive ratio for r33's. definately a good move. think it sits on the fwy at around 2400 from memmory? not bad at all i did a few 700km trips and it didn't annoy me. with that said, i wouldn't say no to a set of 4.11's

3.9s for sure. if its a street car definately 3.9s! if you make decent power you will find they spin the wheels more than enough, but i dont see how 4.11 could be necessary.
