Damn Loren.
You talking about how changing the toe just a little bit would get it to rotate better got me wet. |

Yeah, I'm sexy like that. You should hear me talk about rev-matching and heel-toe downshifting.

First off awesome writeup!!!!!!!!!!!
I have one question though, for those looking to stay in HS what shocks/struts work well with stock springs? Any side affects with that combination? Most are designed to be paired with lowering springs so it seems like this would affect their range of motion (I need something that can go over potholes). Of course if anyone knows of reasonably priced adjustable ones let me know. |

R comps will take you a lot further than shocks in HS though IMO also, keep in mind, if you run a "shorter" shock with stock spring, you'll be compressing the stock spring beyond its original setting, thereby raising your static spring rate :D which isn't bad, but may get you kicked out of HS in a nationals environment. (not that an HS mini is gonna be scared of a yaris.......... )

I'm running factory alignment in the rear (-0.9 camber, slight toe-in), and -2.5 camber in the front with very slight toe-in. My tire wear is very event all around. If I DIDN'T have all that front camber, my front tires would be wearing on the outside edges. Excessive toe, especially when coupled with agressive camber will cause tire wear issues. But, with neutral toe settings, up to 3 degrees of camber is not a problem even on a daily-driven vehicle. (trivia: The factory alignment on the rear of my Triumph is 3 degrees negative camber) |

Running 2 degrees of camber with mild toe settings and doing strictly highway miles might result in 2mm more wear on the inside of the tire vs the outside. Of course, if you do strictly highway driving, you don't NEED that much camber! If you have that much camber, it's probably because you do some mountain driving, or autocross, or track driving... and that performance driving is going to largely equalize the wear. You might still see maybe 1mm more wear on the inside vs. the outside... but who cares? That's close enough. |

What you'll eventually conclude with that setup and really think about it is that a) you don't have enough suspension travel so you bottom out both in hard turns and over bumps and b) the shocks don't sufficiently control the motion of the springs on rebound.
Will it "work"? Yes, but not if you want the car to handle as good as it could. |

Cusco does make a front anti sway bar (part no. 900 311 A26). So its available for a price should you feel the need for it. As I cannot read Japanese I cannot say if it is stiffer than stock or not.
I found that running too much negative camber on skinny street tires reduces its off-the-line traction. It might not really hurt acceleration that much but it seems easier to get the tires to break loose.

The only reason Cusco makes it is because people who don't know any better WILL buy it... not because anyone really needs it. |

We can't be certain of that fact which is why I stated the bar was available but can't speak for its effects. If it would make the car understeer worse like you say it would, then if you took the front anti roll bar off, would it cure the understeer without having to fit a rear anti roll bar?
I think it is possible that a correct front anti roll bar would reduce front roll, and optimize the tire contact patch in the corners, because too much roll unloads the inside tires. I'm not saying the Cusco would do it, because I've never tried it, but it is a tuning option that should be tried before being written off.

And, yes, removing the front swaybar would probably make the car understeer less (it's been done on some FWD cars with success), but while it might have higher cornering limits, the steering would feel very "sloppy" and it wouldn't be enjoyable to drive. One absolute truth about suspension tuning: It's always a compromise. Quote:
If eliminating all body roll was the answer, every race car and high-end performance car would have NO body roll. Eliminating more body roll (with a larger front swaybar) at the expense of moving the handling balance of the car further in the wrong direction is no solution. This whole discussion is much like arguing about lowering springs with ricers. They think that "lower is better" no matter what... and "stiffer and flatter" is better no matter what. It's simply not true. Quote:
Wanna play with what removing the front swaybar would do? It's easy, just remove an end link on one side. The other side will hold the bar in place and keep it from flopping around, but with one side disconnected, the bar will have no effect. Very simple experiment. Somebody do it and report back. (maybe I'll do it when I have time) If you have a stiff coilover suspension, you might get away without the front swaybar. I tuned the suspension on my old Miata with really stiff springs and NO swaybars. People thought I was nuts, but I wanted to prove that it could be done. It took really stiff front springs to get it to feel right, of course. |
