Roll center adjustment kit

I am dropping my evo x on cobb springs and was wondering if it would be a good idea to get a Roll center adjustment kit.

the cobb drop i believe is 1.4/1.3

Thanks!

THE Whiteline Roll Centre Adjustment Kit Part # KCA395 is a great investment with any lowered vehicle as you're changing the geometry of your suspension and weight transfer distribution..

Cheers

If you bought your Evo wanting it to handle like a Subaru, then a roll center correction kit isn't necessary.

The best thing about the Evo X is it's handling stock. When you change it you have every chance of making it worse not better. Why buy a performance car and mod it to perform worse?

It is why you should buy from or at least listen to people like GT worx or Robi spec who test the cars and know the mods make the cars better. You lower the car you need to correct the geometry.

Depends - anywhere from ~$175-$190, however you're going to pay a machine shop to have the ball joints pressed from your lower control arms and the new ones pressed back in. Do NOT cheap out and try using a hammer, you're going to destroy them.

Not absolutely necessary but how many of us have "unnecessary" parts on our daily drivers/weekend track cars?

You absolutely want to talk with GTWorx or Robert Fuller of Robispec.

Here's a pdf explaining their product. http://www.whiteline.com.au/instruction/Z351_KCA395.pdf
I would highly recommend any of their products/great customer service. No I don't secretly work for them. I don't think you stated, but what exactly are your goals for the car?

You're 100% right, it's not going to handle like a Subaru, more like a go-cart!

Awesome replies and info thanks a bunch.

I am not going to get it right away but I will get it soon. Do you need another alignment afterwards?

I'm not sure if you needed me to speak to this. I gave a clipped answer because of the suggestion that adding a low cost mod to keep your cars performance on par is unnecessary. If you lower your car you will drop the front end roll center below the surface of the road. This will translate into additional understeer during aggressive cornering. If you've driven an STI you'd know that they are even more prone to understeer than our cars, hence the reference.
If you get your springs it would be a good experiment to drive on them for a while, get the feel of the car, then install the roll center correction kit and see if you can tell the difference.

Awesome thanks, that is what I am going to do. I will post here in a month or so when I put it in.

I have the kit on my car and it's solely a DD. I wouldn't say it's necessary, but i'd definitely recommend it. I could feel a difference immediately and i always say if you're going to do something you might as well do it the best you can.
