NICE.
tom, can you help me understand the following (in CAPS)
Tarrett monoball upper/lower bearings (CAN YOU POINT TO THIS ON THE PIC?)
ERP RSR tension/compression links (IS THIS ALSO CALLED THRUST ARM?)
ERP rear toe control arm (WHAT IS THIS?)

tom,
if i understood the parts correctly (the operative word is IF), you cannot have all the parts you listed b/c some of them are variation of the same part (now i can be totally off on this... bear with me)..
Tarrett toe link with bump steer = ERP rear toe control arm, except one has bump adjustment
Tarrett monoball upper/lower bearings OR Tarrett monoball ends
You cannot use both. If you have split control arms (which you do), you replace the split part with tarret monoball ends (they are pink/red as shown on your pix). The Tarrett monoball upper/lower bearings is the bearing inside of Tarrett monoball ends, or you can use Tarrett monoball upper/lower bearings to replace the bushings in the non split control arms, inboard side (since they cannot take the Tarrett monoball ends)
where is Rad?

actually, you are correct. there are so many adjustable parts under the car im not 100% which is which. I probably duplicated a few parts in my discription as the cross between Tarrett and ERP is where im probably mixed up.
RAD would definitly know as the majority came from him
The RSR spec stuff (links with "forks") came from HKE46Boy.

I had my old RS with most of these parts on it last year and to be honest, as far as ride quality and road noise goes, i have not noticed any sacrifice/difference from a stock RS on the street. With all rubber removed it still feels the same ride quality on the street, and there is no "rattle" noise from suspension components as one would assume of monoballs which is a bonus since i like driving it everywhere.
I noticed my Bilstein damptronics didnt make any "coil spring noise" like the stock shocks under hard crank from a stop position, however after driving a stock RS all month and finally getting back on the damptronics for this weekend i will beable to give better feedback on them in the near future.
Next week the CUP steering wheel, GT2 seats and full Clubsport cage.
A full interior grand tourer/track car LOL
Did i mention swapping all these parts from one RS to another is time consuming......... LOL

i will have all those pieces on the toy, not the RS.
isn't it strange that these little pieces of alum/steel are so expensive, all those parts add up close to $8000 in retails !!!

I did all these upgrades to my 996 GT3 and the car got a lot better than when I switched the same car from stock shocks/springs to Moton CS.
These parts were going in the GT3 RS, but Tom took the car from me before the parts got there. You can run less static toe-in at the rear once all the rubber is removed from the suspension links.
How good are the Bilstein B16 Damptronics? Well, they were made as an upgrade suspension for the 2008 GT2, a car that uses a better PASM system than the 997.1 GT3. Bilstein developed the PASM for Porsche so they know better. It is not a race suspension, it is a road suspension, with 50% stiffer front springs, helper springs to ensure linear operation (stock springs bounce on the spring perches on lowered cars), and the PASM stiff setting is usable.
I did something similar to this with the Scuderia, all the rubber bushings are gone, and the rest already came stock with metal mounts and monoballs.

UPDATE:
the bilsteins are fair on the street and as aggressive as one would want on the street actually.
The front is noticeably stiffer. they actually feel stiffer in front then stock shocks with PASM on.
The monoball stuff really dosnt take away from the ride quality at all which is positive.
Only the RSR spec items allow more road noise from the tires to travel up into the rear of the cabin to give a hint that it is no longer stock as far as sounds are concerned.
It is not annoying and for a street car that is set up for track it is not a sacrifice by any means.
The car feels "all business".
As result the car now has (and holds!) a really nice street/track alignment. It is like night and day compared to stock RS suspension. Driving into corners takes on a whole new meaning
Will be setting up the bump steer next week for even more cornering performance!
