RJ, pull your head in and stop being an unhelpful smart arse!
Rather than be your usually smug self, why not try to help kudos, being a keyboard warrior alog with your snide comments just isnt helpful.
Kudos, I will go out on a limb here and recommend somone, and I hate recommending somone, especialy since you have had the troubles you've already described, but I reckon you will get resolution with these guys.
You need to speak to Chris Albertini @ Centerline suspension. They do brilliant setups and will either do the setup youve asked for, or recomend what they believe your car should be setup, depending on the driving you do.
They just completed fitting a tein protype suspension system to one of my best mates cars, an MPS6's and its changed the car dramatically. Its gone from what felt like a heavy GT car to a much more nimble machine with more grip and far less body roll. Chris also runs race cars, he does suspension work on some of the V8 supercar teams and he is nothing short of brilliant, so your in good hands
The only catch wil be they are in thomastown on lipton drive, and chris will no doubt want your car for the enitre day, as he will want to test drive it several times before he is happy with it. You might want to at least ring them, and when you speak to chris, let him know you were recommended by darrin who has the MPS6 with the teins he just fitted this week.
