Yes. . .you've got it, supe.
I believe racing-karts still hold the track record at PRI (SIR). . .w/o active suspension members, they stick like glue. (a good example of a "suspension" extreme.)
I happened, one day, to get the bad idea of taking a race-kart up a twisty country road. (don't try this at home) Not a terrible patch of pavement; but in a kart at ~55mph
. . .OMG that thing was down-right scary. . ..hopping and skipping all over . .. rattling my brain like a paint-can in a shaker (i hAveNt bIn da saMe sINce . ..though I hIDe iT wEL

So, yeah, "street/track suspension" is a bit strange, until you start talking active suspensions. Though, of course there are those whom will believe a stiffer suspension is always a good goal. . .or sell.
