hopefully in the next month or so i'll have the $$ to purchase these. as the car will stay a daily driver i don't want to go too stiff. the KW v3's that i'm pretty much sold on have high speed (thing shock frequency speed not vehicle speed) compression preset and low speed compression is adjustable as well as rebound.
400lb spring rates come standard with the kit for my car while 455lb rates come with the kit for the 3.2litre version of my car (to support the heavier engine). i'm toying with getting the 455's for my car since i am autocrossing it. the vehicle is just south fo 3200 lbs with a 60/40 split. it will never be the perfect autocross machine but i'm trying to find the best medium for daily driving and autocrossing. i'm unable to find what my stock spring rates are to compare. the kw's front springs are linear. rears are progressive which is unavoidable due to their wound shape.
driving impression on the forums indicate that it "feels" softer than typical spring strut setups on the bumps and interstates until you get into the turns. seems to figure considering the trick valving they are using. appears as though they are trying to emulate a progressive spring with valving and cut out the negatives of it.
ground control doesn't appear to have an option and all other c/o kits seem to have progressive springs up front :(
miscelaneous stuff: will be lowering .9 inch (min). no camber plates up front don't want the NVH issues, should be able to get -2.0 with adjustments and lowering, some unusual trick bushings mods will be going in up front to emulate pre-recall a-arms(hello to steering feel), camber correction will be going in out back to bring the rear back into spec.
robert just put 500lb rates on his wrx which is of similar weight as the TT. his early initial impressions were that it was a little stiff, but that's without much fiddling. he may be able to dial that out with the compression settings
well this post is getting really long now so i'll make it longer. the other option is to not worry about and if they are too soft order some stiffer spring and hope that the valving has enough adjustment it in to handle them.
unfortunately there aren't many serious autocrossers who know what will work for this car so i'm in nearly uncharted territory.
oh and if anyone wants to loan me about 6 grand i'll get some ohlins from stasis and they will let me fiddle with spring until i'm competely happy.
