As a damper comparison on the same rate of spring they are a cut way above. Super motivated now to press on and get the whole lot in.
You should confirm with Murray but usually he allows enough adjustment in the rebound to handle that sort of spring rate variation (ie; it shouldn't be over damped). When I'm spec'ing a single adjuster shock I aim for a ratio of 3 (rebound) to 1 (bump) ie; 1 click on the adjuster moves the rebound damping X% and the bump damping 1/3 of X%.
I'm sure you know but 200 lbs/inch is way too soft for an R spec tyre, I'm guessing around double that depending on the movement and leverage ratios between the spring and the wheel. On that subject, I'm sure you are also aware that not being a coil over design there are movement and leverage ratio differences between the shock and the spring as well.
It is quite common for Bilstein to engineer additional bump valving in the rear shocks of FWD vehicles and often they run higher nitrogen pressure. This helps the handling by supplementing the often too soft rear spring rates.
