As I don't have a clue how to build a 3D-model and such (and this isn't exactly my idea of fun anyway), I do tweaks based on the stock LFS-cars - for personal use.

However, it'd be great if, for that purpose, I could also tweak other people's mods to my liking.

Have I just not figured out how to do this yet or is this considered a no-no for some reason?

Many mods have derivatives allowed (like this one: https://www.lfs.net/files/vehmods/702A5D ) which means they are open to modification (you can download the original archive from that link). I just hope you can be more creative and don't do some power increase mod - there are way too many of those...

See, I didn't get that! Thanks for pointing it out.

Nah, I usually do "worse" versions of the cars. My last tweak was an MRT with 165/65 R13 road tyres and a Ducati Monster 600 engine with an h-box.

Funny enough, it does feel a bit like that Monster.

I think that it would be nice to have derivs filter in mod page...
