just my 0.2 worth...no modded stagea is the same as a 260RS ..a lot more was done to this car than bolt on bits: ie ..body stress plates in c pillar ...,undercar chassis brace,tunnel brace all unique to this car.. all this is something "stagezilla" will find out why once his 2.7 is dropped into std shell.... bodykit is "functional" autech R& D for cooler flow high speed downforce..not the prettiest but it works..brakes have been perfectly matched to power and weight
having owned the 260 for 18mths now 12 mths on the road and have driven the 2.5 auto there is no comparison really ..you just wouldn`t bother modifying anything when autech have done such a excellent job allready..they are different cars altogether..and to think you or anyone could build the same or equal in your backyard or mates workshop is at best .."dreaming"..
just save up the peso`s and buy the REAL thing ....
then modify that
