I know that these cars have a steller top end and can really do some damage from a 70 or 80 roll but my question is does the top speed vary depending on what generation you have or are they all the same 1989 threw 1998? Is the top speed 140? If so are they governed at 140 or is that the cars maxed out speed? These may be dumb questions for a hardcore sho fan but im just shoing some intrest for other cool cars.
