Winter Upgrades

[WIST2013GT]

Looking to get some new mods this winter and I'm not sure which direction to take. I would like opinions on which will be a better choice:

Beefcakes Torque Booster Setup
or
Circle D 3C and 1 piece drive shaft

My car is driven about 3-4 days a week when its nice and sees the track once a month. I spend a decent amount of time racing in Mexico (roll racing).

I'm not really concerned about the price, and I might end up with both anyway, but I wanted to know what you guys thought would yield the best all around performance gains.

I would probably get the driveshaft and converter first. That way when you get the torque booster and pulley change it will not break anything.

Circle D and driveshaft.
