Title: I want to B Tubbed!
Post by: scottsgretch on August 11, 2008, 06:01:01 PM
I am ready to put my Rover 3.5 in my B, however, now i have the bug to 'tub' the rear.  Has anyone done this and know what i should look out for in the process?  I did notice that Henry Byrd's B in Georgia is tubbed but don't know how to contact him.
Any help or suggestions would be appreciated.  Scott

I guess you've noticed that there are more flares than tubs. The reason is that it's easier, naturally. But how much easier is the real question here. To flare you are dealing with the fender/inner fender seam, and the center inner fender seam and that's about it. To tub, you've got the center seam plus the unibody frame rails, fuel tank, center bulkhead, trunk floor and more, including the frame dogleg. Honestly I'm not sure how you could do it without building a subframe. Maybe I'm wrong about that and for your sake I hope so. But you can get up to a 315 tire under the fender with a somewhat radical flare, how much rubber were you planning on?

I would think, due to the unibody construction of the 'b, it would be a pretty big project. Instead of trying to work around everything, it might make more sense to cut out everything from the rear bulkhead back and construct a tube frame and custom sheet metal. After all that, the 'b is already pretty narrow, you've essentially just created and inline skate. Flares would let you use bigger rubber and still give you a car that can handle. What do you plan to do with the car?
