Guess what you have been doing wrong...

I was just about to say.

Standard setup tyre pressures are too high for the new tyres, setting them down will improve car handling sensibly.

 

[Jyyka Pihtari]

Speaking of tyre pressures, they seem to be pretty low for bias ply tyres. Are you sure the values are in the right ballpark?

I get a gMotor 2 error when trying to load this vehicle. That is, I select the vehicle and then hit "Race" and the loading starts, then stops and then the error:

"Error getting stats for texture WAVEMASK_FK.DDS
Error loading texture WAVEMASK_FX for material ALPHA_OVERLAY"

This is for v.24, Build 1008, Windows 10
Any ideas? I downloaded twice to check that.

The 917K used 21 psi (cold) front and 23 psi (cold) rear at Spa in 71 and 22 psi (cold) front and 26 psi (cold) rear at Le Mans in 71.

Thanks for the info!

Oh, and that proves that the pressures are too low indeed.

 

[P.S.R.]

So the pressures are already too low but I have to lower them further?

Yeah, that is the problem... which the Howston tyres have.

 

[P.S.R.]

yeah same thing with 60s formula vehicles to I'm afraid... Does the current CPM fix this?

Lovely pics, the gearnob is from balsa wood to keep weight down as possible (though McQueen's at Le Mans film wasnt like that, was thin and long-sounds horny I know ).

with the pics i have finish the rim and tyres :
