Ty,
To explain "European school" is little bit difficult but you get it if you go and take a test drive of BMW M6 and after that jump it to chevy pick up. Then you know. With no offence for chevy or any other.
As Steve said all these new subframes are so new at actual results are hard to get. i am having hard time too to make my mind what to do. My needs are front steer rack , 9,5" wide front wheels. But i dont like "fabbed look" . But i really cant afford 7k DSE frame either. So i think i go with DSE speed 2 kit and BRP r&p kit. But after fabbing and parts i am quite close to 4000$ . And i still keep wondering how much more i could gain on full DSE sub????
And then theres a rear suspension...All the years 4 link suspension has been advertised for drag race purpose and suddenly its for curves

So i am really confused too what to do. When i asked this question from DSE i got answer " we have seen improvment on "all numbers" with quadra link" For me - that wont say much.
