The CRX was substantially lighter than the second-gen Integra, so the comparison isn't really accurate. I don't understand why you're asking this question when you're looking at springs that were not designed for your car.
The spring rate is for the Tein Civic springs is:
Front 269 lbs/in
Rear 123 lbs/in
A 120 lb/in spring on the rear of a 2100 lb CRX will produce a firm response because there is relatively little weight at the rear suspension.
With the additional rear weight of a DA Integra, that same spring will be saddled with additional mass to control, producing a more complaint ride. Because more force is being applied to the spring as the body moves forward and aft, the spring will compress more.
But all of this is beside the point.
The best solution is to use the correct springs for your generation of the Integra. That way, you get the correct spring rate to lessen the threat of bottoming out.
You need to replace your dampers (aka struts) anyway, so grab a set of KYB GR2s or AGXs and replace them when you install your springs. If you run any lowering spring on stock shocks, they will wear out in very short order due to the lack of compression damping.
