Surely that would depend on the use track/road and the way you like the car to handle,

Took a long time to get mine right for road and track use, and that was thanks to the adjustable wishbones Jetstreem provided and the complete geo set up, the results are outstanding.

If jet stream were closer i'd be there every other day spending money with them. but they are just too far away for me so im going to set up as per spec in the book.
