Did you change any LSD or brake settings, or are you using stock numbers?

 

[parksideu14]

Stock LSD I think.

 

[crowhop]

Test drive it?
Online or offline?

Will do.

Three laps at Spa (online):
Lap 1: Warmup
Lap 2: 2:18.583
Lap 3: 2:18.097

677 HP
1115 kg
637 PP

All aides off except ABS at 1.
DS3.
Racing Hard tires.

I couldn't match your Performance Point Specs. Mine came to 677 HP, 1115 kg and 637 PP. And that is with the power limited to 95%.
(Mine has been slightly broken in...could explain the slight difference).

Everything else was as you listed.
Used default LSD and Torque Sensing Differential.
Brakes set to F10 R7.


Basically, the car is tight everywhere. There was no turn where I could truly get into the gas as soon as I should have been able to. The car felt a bit heavy with some slight body roll.
Very stable though. No worries about spinning out or losing control.

Probably could gain another 2 or 3 seconds with some tweaks. Camber and LSD would improve times significantly.

I'll see what the rest of the tune is in about a hour.
I tuned it off line.

 

[parksideu14]

Can anyone give me advice for camber.
I'm going to stiffen it and improve the LSD.

In the most basic of terms, increase front camber for oversteer, rear camber for understeer. Increase both until you find the results are detrimental to the car, then dial it back a few clicks.







That's a very simplistic view. Camber also effects grip, braking, turn-in, all sorts, but in essence what you're doing is increasing over or understeer...

Ok dude. As a base tune for this car its ok. I could pull off 1:24:xxx's with the first setup you posted, not the revised version you posted with the 1:26.963. Your lack of LSD tune is the problem. I did some personal revisions to the spring rates and the rear toe. I'm in the 121:xxx"s now. Here's the changes.

Spring Rate
F-10.4 kgf R-13.0

Toe Angle
F-same(-0.10) R-(-0.03)

I am now looking into camber angles and messing with the spring rates more.

its not a bad setup, just not complete... I managed 1.18.xxx on laguna seca with a slightly adjusted setup of yours. your toe is just a little strange...
