@thepain I also didn't like Redux handling and I was able to fix it thnx to guys at this post.
Basically all you need to do is to use OpenIV to:
COPY <root>\update\update.rpf\common\data\handling.meta TO <root>\mods\update\update.rpf\common\data\handling.meta

And that will get you the original GTA V handling.

@Marcel2015 Thanks a lot dude, that worked for me!
The files that I had to work with are actually in update.rpf not common.rpf (common.rpf files are exactly the same as in the mod directory). Here is exactly what I've done:
COPY <root>\update\update.rpf\common\data\ai\weapons.meta TO <root>\mods\update\update.rpf\common\data\ai\weapons.meta
and
COPY <root>\update\update.rpf\common\data\handling.meta TO <root>\mods\update\update.rpf\common\data\handling.meta

And now I can complete missions with high % accuracy even with Redux installed!

@Akila_Reigns said in Any way to install Redux as graphics only?:

@naelm90 Extract the oiv file by WinRAR, then install what you want.

Well, I'm a noob, when I extract it, I don't know which is which

You might want to try to update your scripthook to 1.0.877.1 and update your gameconfig.xml file, though I'm not sure from your description that this will fix it for you.

After I installed Redux mod, I noticed that it messed up most full-automatic weapons accuracy, accuracy is cut by half, completing any mission that require high % accuracy is impossible. So I uninstalled the mod and now I'm running vanilla. I also don't like the vehicle handling changes in Redux.

So I was wondering if i's possible to install Redux graphics changes only without any gameplay/weapons/vehicle changes? Or do you know a mod that have similar visuals? I liked Redux visuals, the street lights effects and the vehicle headlights effects of Redux is very good.
