Don't forget the little Dino, boost everything and your still under 500pp, Hard to drive but I was able to dip under 1:29's in testing. Sometimes I add weight and position the ballast for more of a 50:50 distribution. A bit slower but more predictable handling.
Also try the BMW CSL, 1st engine tune, computer and dumb down the power a little and you have a contender,( at least a contender until the drones of GSX's show up...even then it can do ok...) i added but didn't touch, the racing suspension
Does anyone else notice that certain cars react differently from testing to online racing? I swear it happened to me, The Dino was relatively planted and sure footed in testing, bring it online (same settings) and it's like skating on banana peels!!! What gives? The Corvettes, Focus and Beemers all feel the same, maybe it's just me?
