yeah the ms i have is the 4 map http://www.rs-autosport.net/catalog/...roducts_id=250it was more expensive but i ended up getting that one.

 

yeah but i think the three bar is rated for something like 30 psi,and the 4 bar is rated for like 50+, besides that i am not sure if there is any difference between systems???but i am not sure yet what else is the difference....

 

since your looking for the rear disc brake set up i found 2 for sale on ebay.
Ill give you the links tomarrow if your interested, they were pretty cheap 2.

 

yeah 3 bar is rated for up to 20 psi any higher and you need 4 map i donno if there is any diff besides that

 

YEAH, give me the links... sweet

 

dam, they ended earlier today, srry. but next time i see them, i will post the link immediately.
This should be soon b/c this guy parts out alot of srt's.

 

alright, thanks.... do u know how much they went for ????

 

not exactly what they went for, but when i last saw them they were at about 100 bucks give or take a couple bucks. And that was with ,say 10-14 hours left.
