40:60 front/rear split

Post by aikihook » Sat Mar 08, 2008 4:43 pm

Is it possible to change the 50:50 drive on B5?
Just thought I would post as I belive it is possible to change the B6 set-up. By changing a part in the centre diff - cost approx £200 from the US and only takes an hour or so to fit.

check out these guys they sell a diff but its more agressive than 50:50 think it can go to 88% rear on corner exits

is that not just the centre diff similar to what the RS4 box can do... just split more. It will still send power to the wheels that have grip & default to 50:50. To my knowledge there is no way to change this.

Yeah but it doesn't change the 50:50 default split only how mcuh torque can be sent to the axle with the most grip. The B7 diff is 60:40
with rear bias.

This only controls the possible torque split, not the default bias (which remains 50:50). I also think it can only be done
on older diffs which you can get the casing off.

yeah, so under normal driving it behaves like an open diff and gives 50/50 split, but under load in can transfer up to 80 odd % to the rear ... is that right?

This is the only Stasis one I can see: http://www.stasisengineering.com/Catego ... =50&PID=98

4:1 instead of 2:1 Not much difference there, it would be interesting to see if you could even notice it on the road. There was some debate about whether the B5 RS4 had a different TorSen to the B5 S4 anyway. Can anyone confirm?

Stasis used to advertise a rear biased TorSen for the B5 cars, which seems to have been removed now :( I would pay for a rear biased one I think.

I thought it was agreed the RS4 gearbox has 4:1 and the S4 2:1?

I would really like to get this done to my car. Looked into the statis but was put off when I read about people just doing the washers themselves.

I think my car will have the one piece centre as its a year 2000. There is one guy who managed to split the one piece unit though.

No, I don't think so.
