Lets Talk Suspension

[Jellybean]

Hopefully Chris Wilson will give us some advice!

 

Using Forza 4, Hockenheim and a stock Supra I dialed in some suspension settings , ( looking for a fast road setup but not too harsh on tires)

 

First up

 

OEM SETUP **Please let me know if this is incorrect

 

FACTORY ALIGNMENT SPECIFICATION

 

Front:

 

• Camber - 0.5 degrees +/- 0.75 -- I used - 5.0

 

• Caster +3.5 +/- 0.75 degrees -- I used +3.5

 

• Toe 0.00 +/- 0.80" (2 mm) -- I used 0

 

Rear:

 

• Camber -1.50 +/- 0.75 -- I used -1.50

 

• Toe 3.0mm Toe In +/- 0.080" (2mm) -- I used +3

Taughts: I found her hard to handle, alot of steering input required to keep her in the direction you wanted to go, very tail happy ; To sum it up I found it was a good Drift Setup

Front:

 

Camber - 1.0 degrees

 

Caster + 5.0 degrees

 

Toe 0.00 mm

 

Rear:

 

Camber -1.5 degrees

 

Toe in (total) 1.00 mm

 

Taughts: She handled alot better than OEM above, a little oversteer at times but as a n overall package she was progressive in corners , stable on the straights. Only negative point is I would like the front end to feel more planted and go exactly where I want it to go.

 

 

Dunks Setup

 

Front

 

Camber negative 1 degree

 

Caster 4 degrees

 

Toe in total 0 degrees 7 minutes

 

Rear

 

Camber negative 2 degrees

 

Toe in total 0 degrees 27 minutes

 

Taughts: I found this setup the best out of the three, you can pin point where you want to put the car, stable at high speed , minimal Oversteer ; predictable. As an overall package this is what I would use.

 

 

How all these fair on tyres I don’t know, I do have issues with the front inner edge on mine so I suspect best option is to stay as close to 0 front toe as with OEM setup to minimise the wear.

 

How accurate Forza is versus real life I don’t know but it’s interesting how she handles with the different settings
