more additional mods

I'm trying to figure how to get more additional mods on my car at one time. so far no luck.
has anyone had any luck doing this

 

The only time i was lucky to have 2 additional moddifications is that i had Rk's turbo and indestructible engine (Rk's indestructible engine with the turbo doesn't work), however there was his engine mod and it already had the same turbo mod and didn't require a slot in the additional modification, so I added it and the indestructible engine. Technically 2 additional modifications.

 

It's definetly a huge problem with the way mods work in this game. Something I hope they will address

 

They should add atleast 4 additional slots :/

 

If the filenames, jbeam and flexbody names of mods have an unique name (thereby also not overriding original content) and the slot structure is kept intact mods shouldn't interfere with each other right?
Are there some guidelines like these available?

 

A lot of people don't seem to maximize the slot well
many use it just for a light bar or random part, but the best way is to use it to make more slots
the mad mod was a great example of this since all the extra parts went in the mad mod slots that were under the mod slot
