Seat belts will do no good in an open car, there is no safe strong place to mount and no roll over protection.

Lights and signals yes to that.

GOOD wood wheels are just about as safe as others, metal bends as do wire spoke wheels, you should see the A wheel we have in the shop!
Touring or runabouts are not convertibles, they have no side windows except for maybe side curtains.

I drive mine in city traffic all the time and does fine. A Model T is not a high speed car and has no place on freeways and best not be traveling on higher speed 2 lane roads in heavy traffic, unless there are lots of turns out.

While adding better braking is a good idea, depending on what year, the 30 X3-1/2 tires have a very small road contact area and locking up/skidding is not stopping. The T front end, because of it geometry was not made to use front brakes. It has been done but you need the understanding of how to do it right.

Something like the "Z" head, good idea. Gives a little more hill power.

In case you think about asking later, the Ruckstell is ONLY an under drive and does not give higher top speed.

While mine can do 45-50+ on the flat open road, even with everything in good shape I don't drive it that fast to often unless there are clear roads. Even with Rocky Mtn brakes it still lacks stopping power. Between 30 and 40 keeping lots of distance between me and the car ahead, fun to drive.

BEFORE you jump on a T, find someone that knows them and have them take a look see first. I can't start to tell you how many people I have dealt with that just jumped on one, only to spend $1000's later to make it right.
