Some may be against this or think it doesn't do shit, but i haven't had any tires chunk up or chip off on me by running them backwards. Particularly Federals.

New tires normally don't chunk unless you over heat them by running to much or to little air pressure. The tire will get heat expansion in the middle only if you use to much air. This will make a tire chunk due to the tread not all expanding at the same rate. Like cheap glass cracking on a hot day when you spray water on it.
Old tires just suck....

thanks people.
about the toe in the rear, is drifting really effected by the rear toe? i'm contemplating between having both front and rear toe to zero, or front zero toe with .05 toe in rear. |

Front toe in - stable front end Front toe out - responsive but twitchy front end Rear toe in - stable/somewhat harder to break loose rear end Rear toe out - scary as hell will make you feel like you're driving sideways in the rain with your eyes closed...

I have NEVER had a single chunk come off a Federal.

the ONLY federal tire I have known to chunk was the 235/40 r18 and that was because if you inflated it past 50psi, it would overheat the tire, and chunk. A very normal process for a tire considering it's waaaaay past it's maximum rated heat levels.
Buuuut. According to powers, if you put Nitrogen in them, it's supposed to stabilize the air...allowing for normal temps....fixing that problem. It's not the tire...it's the abuse we put them through. |

I've torn off thread blocks off of 17" federals at 30psi a few times. But I was beating them relentlessly.
If you allow the tires to cool down between runs and aren't going balls out for a long time, nor running a high psi, the tire will last.

nitrogen is really nice shit but damn near no one has it, especially on track. and filling nitro and mixing with air will just cause some wierd shit

thats what i heard on a bunch of other car forums i was thinking ad08 up front but the rs-r are like 90$ cheaper my only concern, a 215/40 feddy will stretch like a normal 225/40, right? never used those tires before |

Toe out in the rear is wack since it makes the care really sketch.
Toe in increases traction and stability. As of right now, I run no toe in rear.

Love that video of the 240 at Ebisu. That's the guy from roadsterdrift, forget his name. I've always been a fan of drifting like that. For me, smooth, precise drifts with smooth driving > super aggressive driving where the driver is flailing around, even with backwards entries and whatnot. Smoothness does it more for me. (that's what she said) That's why I've always liked watching driving videos of Taniguchi, and that's the kind of drifter I strive to me.
EDIT: Shit, I'm a page behind. But yeah. |

smooth driving has more to do with the car setup. I used to flail around like my cabin was full of bees but since this past year I have had a good suspension setup and its sooo different. I let the car steer itself allot more now, with stock caster its really hard to do that. |

for next season I will, I only have 7.3 caster and I still scrub the shit out of the wells. alignment is all about trial and error going up to 7.5 soon then 7.8 then maybe a full 8 if it still feels good |

toe in, in the rear helps with traction and for drifting helps allot with the forward bite. I will be bumping up the rear toe from 0 to -.5 in the rear for next year. (oem spec is -1/16th of a degree in the rear)
for a low hp car i would not bother but if you are going north of 300whp I would suggest adding some - rear toe, you will love it.. |

Then again it doesn't film quite the same either. I dunno then. EDIT: Yeah, that's entirely different, I thought the tube part was just part of the mount or something. |
