Chassis questions for 56 Chevy

[cscowden]

I've got a 56 Chevy 210 post that I am about to embark on the next round of improvements on. I've decided to do more AutoX and Track day events with the car and want to shore up the chassis. I am committed to the original frame given what has already been invested in suspension components and their lack of compatibility with any aftermarket frames.

Top of the list is a TKO 5 speed conversion. I am looking at strengthening the frame with an Art Morisson Center Frame Kit and 2x4 Crossmember. Will this make a noticeable difference? Would a rollbar make a major difference?

The car will be mostly street driven and complete 8-10 track days per year. I need to keep the backseats intact in order to keep the kids included in the fun.

I had RPL Customs in Rowlett, TX do the initial work about 3 yrs ago. Here's what we've done so far:

Ridetech Coilover System Level 1 on original frame
- Strong arm control arms up front
- 4 link in rear
- Musclebar
- Single adjustable coilovers
Currie 9" with 3.55 gears
CPP Drop Spindles
CPP Big Brake kit - 4 wheel discs
Power steering, brakes and vintage air
383 SBC with 700r4

Let me know of ideas to help readying this for track work.
