It depends on what the car is used for. Even if the car is driven on the street a lot I still like the T-350. A 3.42 gear and 28 inch rear tire keep the rpms very reasonable. For a car driven on 2-3 hr trips I like the 200r but for anything other than a highway car I'll shove the 200r in the corner everytime. I can get a T-350 for half of what a decent 200r will cost and the crossmember can be found in any junkyard. I guess I had enough of the 2-3 flare and how the bill to make them work like a 350 or 400 just keeps growing and growing.
Hwy/interstate car - 200r
Anything else-350
