Okay, this is my first tune that I'm releasing for the Lexus IS-F RM.


This particular tune is one that I'm still working on, but the gearbox is complete.



Well anyway, this is my 625 PP tune for what I call the SARD IS-F 615GT.

Chassis Reinforcement: no
Stage 2 Engine Package
Custom ECU
Sport Intake Manifold
Racing Air Filter
Sports Headers
Sports Catalytic Converter
Adjustable LSD


Tires Purchased
CH
SH (default tire when car is new)
SS
RH
RM
RS


Front Downforce: 30
Rear Downforce: 55

Ballast Mass: 15 kg
Ballast Position: +50

Power limited to 88.7% of available power. Current power is 606 hp (615 PS)




1st Gear: 7.278
2nd Gear: 4.275
3rd Gear: 2.926
4th Gear: 2.177
5th Gear: 1.634
6th Gear: 1.255

7th gear is optional if you absolutely must get past 208 mph, but with this current output, you most likely won't need it. But its ratio is 1.034. I've only recently done 7th, but unless you're on SSR7 or SSRX, you won't get very far.


Final Gear: 2.219
Top Speed is set to 273 mph, and 8th gear is at 0.812, but again you won't need it unless you need to get to 334 mph.



Initial Torque: 14
Accel Sensitivity: 60
Decel Sensitivity: 60


Front Ride Height: -10
Rear Ride Height: -9
Front Spring Rate: 14.9
Rear Spring Rate: 16.5
Front Damper (Ext.): 7
Rear Damper (Ext.): 9
Front Damper (Comp.): 7
Rear Damper (Comp.): 8
Front Trackbar: 6
Rear Trackbar: 5

Front Camber: 2.5
Rear Camber: 2.1
Front Toe Angle: -0.19
Rear Toe Angle: +0.32



Front Brake: 6
Rear Brake: 4




This setup has a snug grip with slight understeer on RM, but it can still catch you out if you drive it too hard and lose focus.






I hope this helps some people out.
