Hello everyone! I am planning on upgrading my suspension on my '01 Cobra. Currently I have the following upgrades....... Nitto 555ZR 18" tires shod on Cobra R replica rims. Eibach Pro Kit Lowering springs; Kenny Brown front strut brace. I am thinking about getting the Eibach front and rear sway bar kit which is approx 4 mm thicker than stock. Also I am thinking about installing in polygraphite bushings and then eventually installing the Kenny Brown rear strut brace and sub frame connectors. I am looking for great handling; this car never sees snow nor rain and is driven only in the spring thru fall. I would also like to add full length headers from BBK and also a supercharger; but that is a ways away. I'm looking to get the car braced and getting it to handle really well before I start laying down the power! Any help on the above or alterative choices for sways and choices for bushings etc. would be greatly appreciated! Thanx!:thumbsup:

Before converting to polygraphite bushings, you might consider what a pain in the neck it might be to do that; it takes a great deal of meticulously-detailed work to dis-assemble and re-assemble a steering rack, and there is doubt--at least in my mind--as to whether that much work is worth it for a car that is primarily street-oriented (if that happens to be the case). You might also take into consideration that polygraphite bushings will also, quite likely, affect the ride of the car in a slightly negative way. (Rubber bushings are better than polygraphite bushings at absorbing road vibrations; rubber bushings thus offer a slightly smoother feel in the steering, less driver-fatigue due to road vibrations, etc.). I might have been misinformed in some way, but it has always been my understanding that polygraphite bushings tend to be better-suited to race-only applications.

Regarding the long-tube headers, if the car has been lowered, long-tube headers might be at risk of dragging on high spots in the road/on uneven pavement, and thus involve greater risk of damaging/creating leaks in the exhaust. You might also consider that for some long-tube headers, you have to remove the headers every time you remove the transmission to change the clutch/throw-out bearing, etc. Removing and replacing headers on a 4.6L Cobra engine can be a real pain in the neck, even if you are adept at dropping the K-member and suspension.

I thus believe that mid-length headers are arguably a better choice--ceramic-coated Bassani mid-length headers, for example, since they offer plenty of performance, with less risk of the exhaust dragging, and no need to remove the headers every time you remove the transmission.
:bounce:

Perhaps some others on the SVT Forum have experience with either polygraphite bushings or long-tube headers, and perhaps these individuals might be able to offer more input on the matter.

Thank you for your input! Especially on the headers! I'll check into the Bassini mid length headers. I knew that ceramic coating was the way to go. But anyone else could help me on my suspension mods?.........

I'm in the process of upgrading my suspension. I will be putting on Koni adjustable shocks and struts with H&R Sport Springs. I already have all the Kenny Brown chassis stiffening and think it's awesome (Extreme Matrix Package, Strut and Rear Shock Tower Braces). I'll let you know how the car handles once I get the springs and shocks installed. :thumbsup:
