What is you car doing right now that you don't like?

Right now i have a problem with the Skunk2 UCA's hitting my shock towers. Im not slammed or anything and i have the damper on the hardest setting.

Changing the damper setting will not stop this from happening, it will only change when it will happen. Are you using the Skunk2 to gain camber or lose camber?
Why no go back to a stock UCA? Remember that Slammed is not always the best.

I don't know much about the teins, but your rates aren't that agressive.

The change in the spring rates I think is going to make the biggest difference.
I would tend to run a USDM style setting with the stiffer rate in the rear.
I am currently running 450fr and 600rear on koni yellow. My car handles very well for the auto-x and the Track.

There are 2 things i have not decided yet, and that is the pillow ***** for the tein suspension, I have heard both that it is and isnt benificial without macpherson suspension. The other undecided is the front sway bar. Would it be better to just have the rear only rather then front and rear?

Give me some ideas, and advice on what you think so i can get this together soon.
</TD></TR></TABLE>


Blah blah blah..

Here's what I think
1.) make room for the UCA's, maybe you just need to raise your car, or get rid of them, they are causing a problem with the suspension movement.
2.) run higher rates in the rear and leave your front rates alone.
3.) don't go spending more money on other parts.
spend it on tires, brake pads, and entry fees. Your money will be much better spent here.

If you drive it daily, stiffer rear spring rates may not be the best idea, as it will make the ride much more harsh. I speak from personal experience (380f/450r rates with Ground Controls).

So you have a 19mm rear swaybar and no front bar now. I would think that would be prone to major lift-throttle oversteer, even more so if you use stiffer rear spring rates.

If nothing else, I would at least change the front UCA's back to stock, and get the toe aligned to zero.

front sway bar might help keeping you flat in the corners. But will probably introduce a little understeer.

Personally I'm running 450fr 600 rear... with a stock front sway bar... car handles great!

But... it does SUCK for the street.


If you are UCA are hitting... remove them. You suspension is no longer working once your arms hit....

Start with this and see what happens

</TD></TR></TABLE>

what are you using the camber adjusting UCA for?

Are you trying to get more camber?

Or Are you tryin to get less camber?


As for the front vs rear spring rates:
