Sidewall Height Question

[rogergrubb]

I've got a '65 Malibu and have a set of Bonspeed 18X9 Malibu wheels on order.
It's getting coilovers, heavy front sway, adjustable rear sway, quick ratio steering, adjustable upper control arms
.
Stock 283 at the moment but I do have a real '65 L79 short block on my engine stand. This week I decided to sell that for a nice all aluminum LS powerplant so if you know anyone who wants to buy a L79 or sell a LS... =0)

It's going to be super snug in the rear and I want this car to handle. Maybe a half a dozen Auto-X's/yr primarily a spirited street car.

I have little experience in setting up a car like this for AutoXing. I assume smaller sidewall is better at the cost of my spine when on the street?

Is there a sweet spot for sidewall height when this car is a DD and a AutoXer?

Sorry if I ran on a bit...
