chassis brace and suspension parts.
Ok, here it goes. when you start installing suspension parts that are going to make your ride that much more resistant to body roll, plushness, and some movement, you are going to be asking more of your chassis. What do I mean by that, on the stock suspension it will have more tendency to move a lot.
Now with stiffer springs, high rebound struts, bigger anti-roll (sway bars) bars, your chassis will flex that much more. that is when you start tying it all together with strut bars, frame ties, roll bars and cages.
Once you do this to your chassis, you will let your suspension work that much better, since you will not be loosing any suspension control over chassis flex.
On this car, I know that you need more chassis bracing on the rear of the car. I say this cause if you look on the front of of the car (engine compartment) you will notice that the strut towers are really close to the firewall. Where the good part of FWD cars have them close to the middle.
And better yet on the srt-4, you will notice a small support bracket on the rear of the front towers, to make it even more rigid. No, the reg neons do not have this.
No, I am sorry I do not have any links to my rear arms. But I do recomend the steel ones for street cars.
