well i know us 5 speed 2gnt's can spank the V'6. and the new ones are about as heavier as a spyder...so youll be a few hundred pounds lighter. im gonna say you can take the RS just remove the 12's. if the 90 is in pretty sad shape you can take him...but hes lighter and a 5 speed so i dunno. run them and find out
