Thanks for the ideas. The first two sound OK (though I think 3 cm lower would be about the limit since some of our roads are far from racetrack condition ;-) Can you explain the "strutbrace" in more detail. Our 9-3 already has a couple of braces between the suspension pillars' tops and the top of the firewall, presumably to stop the pillars from going out of parallel with each other when loading a front wheel heavily. So I can't see what else can be done there. Abbott Racing's web site doesn't seem to display this brace either . . . Back in the days where cars had a bit of space in the engine bay, X-bracing could be used for the suspension pillars (McPherson), but I see no possibility in a 9-3. // Robert Matt wrote: > Get in contact with Abbott Racing and mention te following > > Loweing 60mm > Stifer springs > Strutbrace > > Robert Brown <rjbnopsamnetNOSPAM.se> wrote in message > news:38B9CCDF.18539201nopsamnetNOSPAM.se... > > Hi, > > > > We have a 1999 9-3 SE 200.
