So why the toe in on the rear? I thought a dc2 was long enough to set it at 0' ? I tried a few on the rear and liked the 0' more than toe in ( on the rear that is).

The rear is at zero... Or am I mistaken?

Looks like it started off not being zero, but then being corrected.

Yeah, when i printed it it came up as 0'.. Sorry i was wondering.
Whats up with your rear camber? 1.5- 0.8 ???

the guy there could not figure it out... He was stumped last time too.

Maybe I have a bushing that's wearing thin or something is slightly tweaked ??? I dunno.

I think that your alignment is weighted with information about how much you are concerned about the corners and how much you are concerned with stability at high speed and especially threshold braking from high speed.

At Summit Point, if you get through Turn 10 perfectly, it's very possible you'll be at 140 or more at the moment you go into threshold braking for Turn 1.

Needless to say, the suspension geometry goes all to hell in this kind of situation. As the rear end hikes up, you get toe out and positive camber. Can't be helped.

After years of trying what most of us have decided is that you'd want to be at zero to slightly toe out on the front to enhance turn in.

But you would want to be at slightly toe in on the rear, which will assist with straight line stability especially when under maximum braking.

It's worth dealing with this and thinking about it. You can get a full second/lap just because you're more comfortable with how the car behaves when you've compressed the brake zone to the maximum extent.

There's more you can do to help with this, too.

Heavier springs on the front to keep the nose up under braking (which means even heavier springs in the rear).

Better brake pads on the rear than what you have now.

Dampers adjusted to resist the car coming up so fast.

Better == Higher coefficient of friction at operating temperature?

I found this to be true, albeit a bit counterintuitive. If you want to spin the car, what do you do.. yank the e-brake, decreasing the amount of lateral grip available in the rear. So I'm not sure I have a real good explanation for it.

p.s. Rob, I don't have a sheet, but I'm 0 toe rear, and still 1/4 total toe out front. I don't know my camber, but I don't have camber plates so I'll live with what I have. Maybe 3 degrees front, 1.5 rear? I suppose I could try measuring it to get a rough idea.

You might want to consider swapping the upper arms back to their original configuration after reading this here:

Interesting to read that. Alot of variables come into play. I will have to go measure the distance of the center bore to the top of the bottom fender.

I know my LCA's are not parallel. My car is pretty low here so Ill check.

One member states that the handling worsened, I felt as if it was a big improvement. I noticed immediately that there was a change, and if I remember correctly, it was in a good way.

Aside from that all, this might also explain why I got abnormal tire wear this past session. HOWEVER, I do have soft suspension which was replaced by the TEIN RE's. *shrugs* Guess I have to do more test and tuning. :)

New spec's i set up while using a gps lap system "very nice".

Now my 98 R is stock except:
Skunk 2 UCA's front
ingles UCA rear
23mm rear sway bar
jdm header jdm cat
CTR intake cam.

After changing settings over and over at the track i cam up with
"0" toe both front and rear
" 1.8-" front camber
"2.0-" rear camber
caster is non adjustable so i did not even look.

With this set up i was fighting it out with an Lotus Ex all day and winning in the corners.
just an fyi
