hi,
you should know that tuning would go in one way:
ALL RACER HAVE TO USE TUNING PARTS IF THEY WANT TO BE COMPETABLE!
just imagine: you have an xfg, go on ctra... several years we fought with our untuned fwd cars like hell to get good times... now tuning would come into the game... you will have to use max tuning and you will have to acclimate to a fully new car...
now you know why noone wants tuning here? and this is only one argument against tuning.
but there is a possibility to have tuned cars: best example is the xrg. you want an upgrade? better engine? bodykit? USE THE XRT... now you want an upgrade with brutal turbo, sportive look, spoilers? USE THE XRR ^^
you see that in some cases are pre tuned cars
the next thing you should know: the actual average age is 26,28 years (look at LFSW in the LFS racers database)... we are too old for this sh** ^^
