It is still in beta version but still worth a try.

That Ferrari is awesome!

Yeh pretty cool! Like the Lotus as well. Hey uh i don't get Reel Feel? As a matter of fact, is it just me or do you lose steering resistance and FFB when it is used?

Most of the time I don't like that plugin.

I downloaded this though and this one feels great:

It's basically a custom controller.ini. I had to change a few things in it because I have a different wheel, but it should work for you

To fix weak FFB with realfeel plugin
if you change the first 12 lines in the realfeelplugin.ini from the default to this (this will change the default settings which the plugin uses on each new mod)
" [General]
RealFeelIsOn=True
ConsoleEnabled=False
ConsoleRepeatDelay=0.100000
SpeechEnabled=True
KeyRepeatDelay=0.100000
SteerForceInputMax=65535.000000
MinSpeed=10.000000
LogEnabled=False
DefaultMaxForceAtSteeringRack=10000.000000
DefaultSteeringDamper=65535.000000
DefaultSmoothingLevel=0 "
and delete everything after these lines to reset to the defaults, the force will be strong again for most mods

If you use a mod and the force is too strong or too weak you can tweak the settings for each of them individualy ingame by using the key commands in this image
