R390 Gt1 Lm

[Hikari]

I've got a R390 GT1 LM Race Car and strengthened it to 1200ps.
And I've a trouble when I am doing tuning. Can LSD be used to solve a problem what the R390 GT1 LM understeers in high speed corners?

Hi, Hikari. My R-390, used in the R11 Enduro, was set up like this (stock power, though):

LSD: 10/35/20
ASM: 0
TCS: 1
Camber: 3.0/1.0

I think all the other settings were stock. Try running maxim um downforce in the fron but backing off a little on the rear downforce. That will have more effect on the high speed corners than the LSD will.

(ASM and TCS... I've them closed...)
Another method found: The DOWNFORCE... (-v-)
After I increased the downforce, the R390 steers good in high speed corners. And takes hardly any effect in low speed corners.

Thats because at low speeds 85 and below there is less airpressure making less and less downforce than if you were going 150+
Basically the slower you go the more you rule downforce out and rely more on mechanical grip, the faster you go the more downforce increases and that increases your mechanical grip.

So I tuned downforce to improve the car's performance at high speed corners without changing the car much at low speed corners.

Thanks to neon_duke & 3rdgenracerX!

P.S.: I won Mistral 78laps yesterday with this R390.
