Callaway Of the Month August '04

Welcome! The Callaway Owners Group is dedicated to the preservation of the world's most powerful Corvette.

 Dr. Steve Davidson's Callaway CR1 SuperNatural

1990 Callaway CR1 SuperNatural

This month, we feature a rather unique Callaway “CL1” SuperNatural™ Corvette, owned by Dr. Steve Davidson.

Steve enthusiastically shares his timeline on how his ZR1 came to become a Callaway CR1 SuperNatural™ with 500 horsepower and includes a series of pictures to help illustrate his story.

Steve’s car is indeed one beautiful car - We look forward to seeing it again at Corvettes @ Carlisle J  -COG.

1991  Early Spring           Purchased red/black 1990 ZR-1 with 2500 miles as       

                                       terminated GMAC lease.  Original purchase price

                                       $85,000 ($20,000 over list).  Purchased at local

                                       auto exchange for $37,500!!  Plate:  DADS ZR-1


1991  Summer                  Met Larry Merrow and other ZR-1 owners at

                                       Corvettes at Carlisle.  Joined newly formed ZR-1

                                       Registry Owner’s Group.


1991-1996                         Many, Many ZR-1 Registry events and adventures.

                                      Wrote a monthly column called “Kleen Dreams” for

                                      ZR-1 Registry Newsletter/magazine.


                                      Met Tony Cardiello and Carl Gentile and their

                                      Fabulous Callaway Aerobody SuperNatural™

                                      ZR-1s – seed sown.  Lots of negotiations at Corvettes at Carlisle summer ’96 with the Callaway Staff.


1996  Fall                        Local pizza shop owner had a used 1990/red/black

                                       ZR-1 parked in front of his shop.  Super car not so



                                       Also went on road trip with friends from          

                                       New Zealand to pick up a new Viper – took red ZR1,

                                       red WS-6 Firebird and red Viper.  Firebird and

                                       Viper got lots of looks.  ZR-1 was ignored by

                                       crowds, the final impetus to make the ZR-1 super

                                       special again.


                                       Much discussion re: Lingenfelter vs. Callaway 

                                       modifications.  Went for super powerful, tasteful,

                                       elegant road going touring car that the Callaway

                                       package offered.  Selected the new Viper GTS

                                       blue metallic paint for rebody after seeing (then)

                                       new ’97 Viper GTS coupes being unloaded from

                                       factory enclosed trailer at Viper dealer.


Winter over 1996/97          Old Lyme  (see pictures)

                                        1.       Body disassembled, new AeroBody™ installed, full repaint to Viper GTS blue Mica metallic.

                                        2.  Transverse leaf spring and tire carrier pan removed.  New Callaway header CATS and “Double D” tip centerline exhaust installed.

                                        3.      Callaway coilover shock suspension system installed.

(See picture in front of Callaway Headquarters in Old Lyme)


Winter over 1997/98          1.  Full SuperNatural™ 500 HP (“490”) engine package completed – dyno sheets = 500 HP!

                                          2.     OZ  Mito modular 3 piece rims, 18 x 10 FR, 18 x 12 rear and Pirelli P Zero (Yellow) tires

                                                275/35/ZR18 FR, 335/30/ZR18 R installed.

                                          3.     Custom fabricated Brembo brakes with stainless steel braided lines installed.

                                          4.     New plate:  500HPCR1 installed.


500HPCR1 has been on many high powered adventures, has won lots and lots of trophies and events, and is even more “super special” today than when born in 1997/98.

PS:  Recent overheating/hydraulic clutch problems have been completely resolved and 500HPCR1 is performing perfectly, making great, smooth, sweet sounding power.  See the Corvette Action Center Callaway Chat site for full details.
