Playing with the 2000 Nissan Silvia spec-R
First, a simple RWD A-tune based on stock engine.
Gave it a Ings front, West wing, West rear & Nismo sideskirts.
Stock tires maxed F/R, step 1 widened, the "last" Work-wheels.
Racing gear+diff, sport driveline. Rally suspension (lighweight car=soft setup) Race ARB`s, sport weight
Engine: Race air, fuel, exhaust, block, compression & turbo. Sport ignition & flywheel
= 329Kw, 486Nm, 1118kg
This gives good tourque but a rather narrow powerband, a good match to the quick-shifting 6sp gearbox.
And the sport flywheel makes the engine fast revving & responsive to match up.
Setup: gears 3.55, first is "opened" to 2.89*, 6th is shortened to 0.80. * to reduce takeoff-wheelspin
ARB`s 14.40 F/R, springs 22.9 F/R, rideheight F: 19.8, R: 19.5. Dampers F: 3.8/9.0, R: 3.9/9.0. Diff: 56/50
This is a good basic setup, the soft suspension matches the light car & the tiregrip.
S1-Widebody racetune
First; 3.2L I6 engine, turbo, AWD, bodykit. I gave it a West-wing and some OZ-wheels.
Racetires maxed F & R. Race gearbox, driveline & diff. Street brakes (lightweight car)
Race suspension & ARB`s, raceweight reduction.
Engine: Race "everything" exept sport cam & flywheel, stock coolers
= 475Kw, 660Nm,1059kg.
Setup: gears 3.75, 2.89 1st, 0.80 6th. ARB`s 30.0 F & R, springs 52/50, rideheight
17.1 F & R. Dampers 4.8/14.0 F & R. Diff 55/0, 55/50, 55
Simple as that. Soft enough to make it handle but still in control, even in +300km/h
A stiffer setup will understeer & mask most of the "information" from the road.
The diff-setting makes it a "full AWD", the frontwheels will pull it through the
corners. More power to the rear & it will handle more like a RWD.
