Hotfingrs , we didn`t run them all the time .... you are correct about the tires . Changed from the street shocks to the 90/10`s just before going to the track and disconnected the sway bar then also . Put it all back shortly after leaving. Some of the really anal racers also put undersize rear shocks on to allow more weight transfer , however , keep in mind I`m talking about guys racing 3400 lb cars back in the 60`s .
FWB , sounds like you answered your own question when you said it hooked up when you had front shocks that were toast . Probably gave the same effect as the 90/10`s ... or in our case ... worn out shocks .
If you have coilovers , changing shocks can be a pain .... maybe a spare set of front shocks/springs for drag only ?? After all , it`s only money ... right ???
