foodog, whilst height and weight can make a big difference in how comfortable you would be in a T, so does seat design and placement. I'm 6'2" and 270 lbs, so I was really concerned about it. I drove out to CT and visited Total Performance. Brian and Jim were very gracious and allowed me to "try on" a couple of options. I found the Total seat insert was just the ticket for me. It allowed me to sit down into the car a lot more, as well as moving me back a bit and tilting me so my legs would be at a more comfortable angle.
Was the comfort level so high I would want to jump in the car and drive it to the West Coast? No, it wasn't. But I was looking to build a cruiser, not a long distance runner, so I was pleased with the decision.
Several years ago, we had some downtime at a race, when a section of bleachers had collapsed.
We ended up with a bench-racing session at our trailer. Larry Morgan has just started driving the Rod Shop Fiero in Comp Eliminator and we were talking about his transition from Super Stock into Comp. He made the comment he wanted to race so badly that he would race anything he could get into. He the pointed out he wouldn't race something he got onto, only what he could get into. As in, no motorcycles. I always found sitting on a regular T-Bucket bench seat left me feeling like I was sitting on the car, rather than sitting in it. I feel like if I lean over to far, I could just topple out of the car. And that was a little unsettling for me, even though I spent years riding bikes.
Spend time looking at your options. Other than those pesky sands of time, there's nothing saying you have to build a T in a certain amount of time. Look at what other people are doing. Talk to T-Bucket owners. Ask questions. Make notes. Pay attention to things you like in other cars, because you might find those things are easily adapted to a T. Keep your mind, your eyes and your ears open, so you soak up everything you can. After a while, you'll start to develop a plan of attack for the T you are going to build. Then you can start to move forward. As Youngster mentioned, keep your own abilities in mind and you'll be fine.
And, as RPM mentioned, I just happen to have a complete Total kit for sale at a very attractive price, if you decide that is the way you would like to go. I'll leave my shameless plug at that.
