My target:

6* pos caster
Zero toe
2* neg front camber
1* neg rear camber

Results:

Front
4.5* positive caster
2* neg camber
zero toe

Rear
1.5 neg
.11 toe

I rotated my Tien camber plates to get the added catser, but expected to reach 6* by doing this alone. The upper end of the strut is completely adjusted in toward the firewall, but still I am only able to achieve 4.5*. Since I already had 3* I'm not sure I'll see a notable reduction in understeer. However, since I have no interest in running more camber than what I can get from the eccentric bolts I suppose I'm somewhat pleased with the outcome.

I thought someone might find it useful to know what my results where with this setup since I was curious myself prior to spinning the camber plates.

 

Other things affect understeer more than what you have done. Caster helps, but its not as big as others. Caster changes you have done are only 1 degree different than OE. Very slight change.

What is the rest of the suspension - spring rates, sway bars, struts? Tires - type width? Type of racing?

 

Now Smike, dont start going around diluting peoples minds with...... facts

 

An extra 1.5* is about what I would expect from rotating the plates.

I actually think it would be fairly noticeable...not necessarily as a reduction in understeer but still an improvement.

Yeah, steering feel will be changed. Understeer, doubtful.

OP - rest of specs?

 

I was simply posting the results of spinning the camber plates. Like I mentioned I had expected a more adjustment. Had I been able to achieve the 6* I wanted I believe I would have seen a significant reduction in understeer.

Please enlighten me oh great suspension guru on how to properly set up my car for drag racing, prosolo, and street performance.

 

There is no one magic bullet for the events you listed. But drag can be excluded. Prosolo and street can be similar. But drawbacks to running aggressive setups on the street.

Take a moment to search alignments and spring rate choices.

And again, what is your current setup?

 

Ok. Perhaps you're well known on this forum, but I don't know you whatsoever. My 20 years of racing experience has given me a little knowledge about car setup.
I really have no intention to sit and argue with a stranger on the internet.

Tien...S-Techs

That right there wont help with the understeer issue. They are too low (riding on bump stops) and too soft (poor spring rates).

Good struts though. I would look into changing the springs out to a set that is better suited for AX and spirited street use.

 

So you say my springs are crap and come in my post with a condesending attitude and tell me I have a poor attitude? Wow...nice.

How exactly does my spring rate affect my understeer. I'm looking for spefic factual and useful information here, not some generalized blanket statement.

 

I was expecting that you were going to give me an answer to each...not a one size fits all answer. Why is drag racing excluded?

 

This is well covered on here.

Your front end is slammed. Which does help reduce understeer, however, you have no suspension travel. Which increases understeer. And only +12 up and rate in the front is also not going to help understeer. Car is currently fighting itself.

I took it out because its for going straight. Means no camber, no toe. And its totally different than AX and street.

 

Do some reading on those tein springs there certainly not helping with your understeer. I think everyones out to just provide useful information ( no bad attitudes)

 

Thanks, I bought the car with them already installed and may look into replacing them in the future. For now, I'm setting up my car the best i can with what is already there. I may not have the ideal setup, but I do know I can optimize it. I thought some might like to know the affects. I had no idea I was going to get criticized for my setup.
