Toe angle

[ravydavy]

Noticed the car was very unstable above about 80 kmph so just took it for a geometry check.

The technical manual thing say toe should be -30 (-15 each wheel I take it?) but the hunter machine had the correct setting as +30. All of the other settings mirrored renos.

Anyhoo..car feels much more stable at + toe. Has something been lost in translation?

I always thought + toe tended to make a car less stable at speed but with better turn-in??

 

[ravydavy]

It's the other way round I think.

+ = Toe in
- = Toe out (unstable at speed)

The front before adjustment was -10 L/ -6 R as was rather scary.

Not sure why the technical manual says -30 toe? [smilie=doubt.gif]

This has been an area of long running debate. The formal doc has always said -30 and certainly the cars came like that along with the fronts scrubbing their insides out that bit faster. Some other records plus info found in tracking machines has had +30 with a suggest that perhaps Renault changed their minds. Some have reported positive results of going to +30.

Aaaah I always thought + was toe out and - was toe in. Learn something new every day!

Looking at the info from one of the early test Vees at TWR PP 170

Looks like the Reno manual is a typo then.

No way a car should be like that at speed intentionally [smilie=icon_eek.gif]

Ha! Shows how shit the ph2 clutch and flywheel is. Pointless upgrade for the sake of a bit of noise.

Very interesting James. :approve:

PH2 owners: even Renault think the Ph2 FW hold the car back! :s

Agree Brett. Although I spose as Renault intended the car to be a GT car that transmission noise was an important consideration.
