Well dunno what to say, I bought my EVO from EricR who had the suspension set-up by Robi himself. I don't know for sure if someone else aligned it after Robi or whatever but I am very pleased with how it is AFTER my friends at the Tire Factory had their way with it.

It no longer rubs ever, under any sort of braking, or turning and it no longer tracks the road like crazy. It was toed WAYYYY out in the rear. When I bought the car it had brand new 275 PS2's on it. After putting 3k miles on it my fronts were down to nearly the cords! I rotated them but I am sure they will need to be replaced soon as is. It had an insane amount of camber in the front. I didn't need 275's because I wasn't using half of the tire as a contact patch.

I am not trying to bash Robi but hopefully i can find out what the theory was behind this sort of an alignment. I understand the front camber to be put aggressive since it was a track toy for Eric but the toe in the rear boggles me.

 

What were the suspension settings before you changed it?

 

Did you ask Eric?

 

did you buy a track car and drive it on the street? those sound like settings that are used only on the track/autox circuit. maybe it was setup for that only, and street driving was not supposed to be done?

 

HURLUHURLUlululu

 

 

call me......

 

I will scan and post the alignment specs when I get done with work. I haven't had a chance to talk to Eric yet, Poppoff.

Literally the rear tires were like this: \ /

 

Rear toe out is used exclusively for better turn-in response. The more toe out, the better response at the sacrifice of stability. It's no wonder you were tramlining with all the toe and negative camber. This alignment sounds like it was for the track, and should be treated as such. I'm surprised you didn't get the car aligned earlier if you knew it was a track car and you were going to be daily driving it.

In answer to your original question, the theory behind the alignment was to make the car as fast as possible on the track. Robi ain't dumb, and I can almost guarantee you it was made that aggressive on purpose. It's too bad you corded a couple of tires, though

 

^^^ I didn't think it was going to be THAT aggressive. Eric only used it as his weekend toy. Live and learn. Oh well.

 

I didn't change the alignment after Robi aligned it with his laser setup down at Pina. He told me that it was -1.6 to -1.8 camber front with 0 toe. The rear was supposed to be -1.0 camber with a slight toe in. Funny, I had thought that I didn't have enough front neg camber and was thinking of putting a works camber plate on it to get -2.5.

I only put a couple thousand miles on the car after the alignment and really didn't have much of a chance to experience wear. I too, noticed that it tramlined on rutted freeways but thought that it was because of the neg camber and zero toe. That's pretty normal with an aggressive alignment.

Just curious, what were the alignment specs before you had them changed. Are you sure that your new alignment specs are accurate. There's a lot of alignment shops that don't do accurate work.

 

^^ I am almost off work and will post up the specs for ya Eric, I can guaruntee you that the set-up you wanted was not the exact set-up you got. It had camber AND toe in the front and an assload of toe out in the rear.

I am positive this shop is trustworthy as my best friend owns the Tire Factory. I have had my Corvette, boss's Viper, auto-x cars, PIR cars, etc come to them for an alignment.

 

Just goes to show you - who can you trust? (it was a long day for Robi that day)

 

Could the toe have wandered out through normal usage? Hit a nasty bump? I like my cars loose, but there is a limit!

 

Ok so instead of just scanning it in I will just list it:

Left Front:

Before =
Camber -2
Toe -9/32

After =
Camber -1 19/32
Toe 0

Right Front:

Before =
Camber -1 3/32
Toe -3/8

After =
Camber -1 5/16
Toe 0

Left Rear:

Before=
Camber -1 3/16
Toe -1/16

After=
Camber -29/32
Toe -1/32

Right Rear:

Before=
Camber -1/2
Toe -3/16

After=
Camber -29/32
Toe -1/32
