In chassis and suspension setup is there any difference what so ever between 1/8 and 1/4?

If the car is geared different I would imagine the IC and shocks would be setup different to keep the car off the bumper, some guys run the same gear as they do in the 1/4 and just make 1/8th mile passes, while dedicated 1/8th mile guys will gear it to make it finish in top gear in the 1/8th which is much more aggressive considering you'd go from something like a 3.50 gear and run 165 in the 1/4 and you run 122 in the 1/8th, you'd have to run something like a 4.88 gear to make the 122 in the 1/8th in top gear, so with a th400 you'd go from a 8.68 to a 12.10 first gear ratio which is a good start to being on the bumper quick.

Well put, my slow car is set to hook, there is no way I could optimize it for an 1/8th mile track.
There would be no way in hell I could get it to hook without choking the launch way down.
It's much easier to run a 1/4 mile car at a 1/8th mile track.
That's why most guys that have both in their area go with a lower gear.
As for shock settings, launch rpm or tire pressure ect, they should be the same.
