I don't suppose anyone has had a go at fitting Rogers bump stops to an ARP4, with coilovers instead of leaf springs, have they? When loaded my springs do bottom out, with quite a bang too. The alternative is harder rear springs, but that will harshen the ride too or get some longer springs and wind up the clearance a bit.
Unfortunately these bumps stops need a damper hoop to attach to and I’m fairly certain the 5 link cars don’t have them.
PaulJ, I have a 5 link Roadster and have swopped the OE coilovers for some designed by SSL (Suplex) you get 2 springs of different rates, adjustable spring preload & adjustable shocks, worth speaking to them
The SSL coilovers Jon describes work in a counter-intuitive (to me) manner.

The two springs top long, shorter slightly stiffer lower operate in series to mutually dilute overall spring rate. This gives a softer ride for the first approx 25mm of compression travel from static. Further compression causes lower spring to become coil bound despite its standalone higher rate. This leaves upper spring only in play and an instant rise in overall rate to limit roll, as no series rate dilution.
The factory OE answer to limit roll was to use a single high rate spring which worked, but left a harsh ride. The SSL solution answers both these issues with softer more compliant ride stiffening quickly to limit roll to an even greater degree than OE, and instantly noticeable on first corner after fitting
