I just found the ranks on lfsworld and I must say I love it. It gives me a real target to shoot for and easy to see progress instead of just "I wanna go faster".

It seems that the race_s set should be enough to at least beat the benchmark. I havn't done it yet but I suck so that's not saying much.

Are there any combos where race_s is just not going to be enough to top the benchmark with a good driver(not me) behind the wheel?

Race_s sets will help you out a little, but if you want to get a benchmark, may I suggest team INFERNO Setups?

How do I get my lap times to register on LFS World?

Yeah I know about the Inferno sets. I was really more curious if there were any combos where a good driver couldn't get Race_s to beat the benchmark. I'd think it would have to be a downforce car.

Say RB4 on SO long rev. race_s is enough to make the benchmark easy if I can drive well enough, but is it good enough on say the FO8 at WE International or would I actually need a inferno set for that one.
Also note I'm looking to beat the benchmark w/ race_s, not the WR.

You should be able to get close to the benchmark with a RACE_S set, maybe with a few little tweaks to the gearing/downforce on certain combo's.

You can either join races online or you can record hotlaps and upload them to the site.
