Along with 1000 commits to SR3 repo just now

Right, that'd be good. I'm eager to switch to SR3 completely with new content too, since merging from SR to SR3 takes some time.
Anyways I just noticed, are you driving only U6 lately? Because I just drove few new tracks like BarrelFun, MilkyWay, Oversize and this is way easier with U6. With cars (I drive SX usually) not so much. And when I was driving tracks ghost (ES always) then sometimes I needed to boost to jump, or even not fall off on Oversize etc. And underwater, man, normal cars need to boost all the time, I dislike underwater for this. Or low density fluid (I changed to it on BarrelFun and will do on MilkyWay). Challenges need to have boost: always for these tracks.
Ah I should add some info in tracks description probably (to each hmm). And I will make a challenge with only U6 on those probably too, this will need testing its drive times though otherwise could miss it.
Anyways if you could also consider testing other vehicles or adjusting tracks for them I think it'd be best.
