Right, I would like to be fast at Kyoto Ring National and with or the FXO or the RB4 ! I first need a

-fast hotlap setup
-endu set (with tyres who will last as long as possible) - need to do 32 laps
-maybe some hints about the track can be handy

Anyone can help ?

Oh, tiny detail, I use ks But doesn't mather for setup, I can adjust the steering myself.

For a hotlap set you can use the blackwood wr one i'm sure it would be fine. I used an older one to hotlap a while ago which I did with like 6 practice laps, haven't felt like hotlapping or even racing on line much recently. Just take out some camber all around and lower the pressure a bit if you have problems with tires gettin too hot.
