I'm going to write it for the 100th time just for you.
We don't drive stock xrts.
We have xrts with extreme suspension mods. Springs, dampers, rollbars, toe, camber, you name it. We can put extreme brakes in etc.
We can even adjust gear ratios by 0.001.
So there's no reason to have back the settings for - steering lock, tracking and caster.
And ofcourse it would be a real pity if all setup options dissapeared from xrt, fz5, fxo etc. Because then street cars would become utterly boring to drive and would handle like shit.
It's just - we can do extreme race setup for xrt. Why not let us do drift setup too. Why not also implement feature that forces people to race on stock setup.
And increasing steering lock to 45 degreese isn't extreme at all. It's an easy and most of all cheaper mod than buying adjustable suspension or getting super strong brakes. Having a steering lock like on that vid would be extreme. But so are other xrt setup options..
So to sum it up. You are a real hypocrite, unless you always drive lfs cars with stock "hard" setup.
