I relly like the tein flex kit with the efdc. but it is a little pricey. can someone inform me of a particular set up that is just as good but not as expensive.
second question can someone try to explin the difference in handeling once suspension and sway bars have been added to their Zee. and does a after market strut bar rely make a difference.

 

i think the price of the flex is about what to expect for the what you'll be getting. cusco has their zero1 coilovers which are priced a little lower but you lose dampening adjustability and there is no sort of edfc functionality.

which the suspension and thicker sway you'll find significantly less/none body roll in cornering. a quality strut bar does make a difference in negating chassis flex, you'll feel it in turns when you add some power.

 

Ah, the million dollar question - how to make your car handle better. I think it is easier to get understand how to get more hp than it is to make more traction.
Tower strut bar - I assume you are talking about your front since the rear is way overkill as it is? Anyway - the worse thing for a high performing car is body flex. Many different items work together to prevent body flex. Tower struct bars are one of the key elements to prevent this. Now, do aftermarket one really make a difference - yes and no. Yes - if you are able to put more load on your tires in a corner than stock (like sticky tires, overcoils, lower ride height,..). Yes - if you can get actual data from the manufacture that states how much stronger than stock it is. No - if your car makes the same traction as stock and No - if you can't get any data from the manufacture. But, most of the aftermarket one's do look better than the stock
Sway Bars - these act as a spring. The transfer load from one wheel that is in compression to the other wheel. The stiffer the spring, the more transfer of load. Thus, the sway bar will determine how much body roll your car will have. Just buying a sway bar won't make your car corner better. You need to tune your sway bar to your driving style and your suspension. That is why most manufactures make adjustable sway bars. You can decrease understeer or oversteer with sway bars (to a limit).

If you get more interested, buy a pyrometer and learn how to use it. It will tell you everything you need to know about the handling of your car and where your problems lie. I bought a handbook on handling and it really made a difference on my understanding

 

Oh - a better option than upgrading the tower strut bar (since you already have one on your car) to reduce body roll is to buy a Under Chassis Ladder Brace.
