necros is right on the money - And a decent launch helps ALOT - a few more PSI of boost - aftermarket ECU - and some good tyres on that - would see it into the mid/high 12's
the 205 GB makes the car defiantly zippier - over the box mine has - though for top speed - the long gears of the standard 185 Gt4 would see it outpacing the others in the end ! ( i think )
also removing some of the piggyness of the 185 helps - Start with the front bumper - - swap that to the grp A spec bumper - and the alum mounting bar instead of the chunky plastic standard one and steel mounting bar andyoull see it shed a few pounds over the nose ..
