even tho the s2000 class is "lowpowered", they are tuned for racing/rally, but LFS TBO class is based on purely stock cars, from the '90s. Also, seq. shifting was implemented in rally some time ago already, for being H-shifted too hardcore.
You are mixing things up, stock street cars with rally senseless.

Quote from Sir moi 407 :

And I'm not saying to put all TBO in sequential...

No just ALL apart from the dull as dishwater FWD one

Guess what; auto-clutch make all the cars sequential. Use it.

Quote from Sir moi 407 :

Cars with inline 4 around 2000ccc and 200horses still exist
Look at S2000 class in WRC Those cars are Sequential and the motors are nearly like TBO

Look at the bodies of the TBO cars. They are obviously not current model cars, regardless of displacement or cylinder arrangement or output.

First think, then post.

His request was valid in the sense of making the cars faster, it would just ruin the driving enjoyment and wouldn't be realistic, that's all.
