I can say from my expierence....call Tony at air ride technologies!!!
I will say at first when building Rogue I was skepticle on all I read, and heard about their stuff...however. First test drive and I was IMPRESSED!!
first off, just the smoothest ride in a muscle car I have ever been in.
second, responsive...man just un-real, a few miles in to it I got a grip on things, and started cranking on it....on the street by far the best stuff you put under a car! On goodyear eagle f1 run flats...this thing would just turn I couldn't believe the performance....i could emagine the track
This stuff seems to work great...and as a package you get all you need.
I'm pretty sure that Phillym5, (who owns a modded '02 m3, lots of susp. work)
wouldn't want to take the same wager against Rogue...of course the only problem with that car is the over abundance of power, she can get away fast!
I'll second the stiffening needed...box that thing up!! solid mounts, threw floor connectors, moly cage, and get the center of gravity as low as possible...and don't think the big block will hinder you much with right set up,
(and possibly alum. heads if not already on it)
Not to step any toes...there are some very good set ups out there and mentioned here...this is just my exper. and opinion.
thanks.
