I am rebuilding my transmission for a drag car, currently in using type r. I drive to the track though and I hate being at 4500rpm at 120km/h. Any faster even passing I hit vtech and boost.

What gears should I use to lower my highway rpm while maintaining a good quarter mile?

 

Ls 5th
4.7-4.9 FD
LSD of your choice

 

and leave the rest of the gears the same? what are the best gears for drag with boost.

also is lsd better?

sorry, im new to building

 

what size slicks? horsepower? most of the time a strait gsr gear set and 4.4fd work great.
