I believe you are referring to Endurance Brasil skin pack, right?
I think the title are quite confusing (my bad, gotta change it now). Recently I've repack my skins from Metalmoro and MCR2000 from Endurance Brasil skinpack into two new packs, that replace default Reiza series.
I've decided this after AMS release v1.4. Several cars have their VEH altered and series have new parameters, so it's quite annoying to fix all my skinpacks in RD in potentially every new AMS release.
On top of that, I have a feeling that, no matter how much time I spend tuning and honing my custom Talent files, the AI from default series feels better, more combative, more fun.
So, because of this two reasons, I kinda quit create new series, and instead I'm just replacing default Reiza skins (which are awful) to my new ones.
I'm doing this with several series, for my personal use. Basically I'm dowloading packs from RD and elsewhere, and repacking it to replace default series. I've did it with Boxer Cup (mix the Super Boxer Cup and Australia Cup from RD), the Marcas (got the BTCC 2011-2016 pack) and SuperV8 (the 2017 RNR skinpack). Since it's not my work, I can't put in RD, It's not fair to the artists that put so much effort to made them.
But, since Metalmoro and MCR2000 skins are my work (I've took almost a whole month to paint them all), I've decided to put them here for the community, so they can use nice skins online
That said, I've also recently upate my Endurance Brasil series to work with AMS v1.4 onwards. It's another download.
