Z06 RM help?

[phil bell]

Im currently setting it up for the ring' and have problems with it being unstable under turn in,such that when i bleed off the brakes upon entering a corner,the back end steps out...the suspension is soft enough and the diff lock isnt unreasonably low...settings as follows

SUSPENSION
ride height F;+5 R,+5
spring rate F;12.1 R;10.8
dampers(ext) F;8 R;8
dampers(comp) F;7 R;6
a.r.b F;5 R;6
camber(-) F;1.6 R;0.8
toe F;-0.05 R;0.15

LSD
initial torque F;0 R;8
acc sens F;0 R;31
braking sens F;0 R;20

BRAKE BALANCE

balance F;5 R;2

I've been using the Corvette Z06 RM quite a lot, It is the third car I purchased in GT5

Now on to your settings, here's my settings that I've been using on all tracks.
A big deference between yours settings and mine is that I do not use LSD. I do buy LSD but I do not use it.

Down Force F/35 B/60
Ride Height F/0 B/0
Spring Rate F/5.0 B/5.0
Dampers(ext) F/1 B/1
Dampers(comp) F/1 B/1
Roll-Bar F/7 B/7
Camber F/0 B/0
Toe F/0 B/0

LSD Off

Breaks F/5 B/5

------

Try these setting to see if they can help

Just try reducing rear extension; it *should* keep weight from transferring forward quite so suddenly.

I'd point you to my own tune for the Z06 RM but it being slightly unstable under braking is the #1 gripe with it; I don't notice it with my driving but others do, so... Use at your own risk.

thanks guys..especially rotary junkie... by the way,got any advice for LSD tuning?

 

[Rotary Junkie]

What I use is:
Initial: 0/7
Accel:-- 0/25
Braking: 0/5

You may want to raise the braking sensitivity somewhat if you're still having problems with the tail trying to step out; 15 or so should make it dead stable.

Ok,I'll give it a shot..just wondering,does the diff lock(deceleration) activate under braking or as soon as youre off the throttle?

 

[Rotary Junkie]

Any time the car is being forced to slow down, be it via the brakes themselves or engine braking. That said, if you apply throttle while braking it will apply the acceleration value.

 

[phil bell]

OH! ok isee,always wondered about that..thanks again..z06 testing shall resume!!

I would also lower the ride hight, better handling mid corner and exit

 

[phil bell]

yeah,but im really afraid of bumping the nose on the kerbs T.T

The Z06 can't be lowered, really. I find a slight raise to the rear helps exit a bit (I run 0/+15) but aside from that...

 

[phil bell]

yea,i can see why,vette understeers a little.but i prefer that.Maybe i will try having the front lower than the rear...

Done and donecar now handles great! I can now modulate the brakes in corners without problem and the car handles smooth in general with good traction while having 570hp and race hard tires.Thanks guys!
