The standard multi's on the back of my Capri really need replacing but i've been wondering for a while what I should replace them with. Most people seem to opt for single's as they were fitted to 2.8's, but I want to know a bit more about why rather than just following the 'crowd'...
I'm presuming multi's are actually stiffer than singles?

I would say single possibly give a smoother ride that the multi leaf, but I suspect the true answer lies more in the fact they're probably cheaper to make. In the case of the Capri, I was also under the impression the 2.8 springs also lower the car. I don't have a manual to confirm for a Capri, but I'm sure that single leaf Capris also run an ARB on the rear. You would need to do some research on that, other wise you could actually make the car worse as it may roll more in the corners. I'm about to fit 2.8 springs to my Corsair, I then read somewhere that later single leaf Capris had ARB on the rear. So be interested in the answer to that.

This is a common debate with leaf sprung Land Rovers where the singles are known as parabolics. I've had both. New multi leaf performance are probably the same as single leaf. However when multi leaf gets wear ridges and bind together with rust then their performace deteriates making single leaf seem superior. For a proper comparison you need to compare new multi leaf otherwise an unfair competition. BTW The Frieght Rover / Sherpa / LDV has simgle leaf made out of composite material ! Somewhere, deep in the garage, I've an ancient tool (pre WWII) like a modified G clamp that allows the multileafs to be opened slightly so grease can be added. To help multileaf keep their performance you need to keep free of rust / dirt build up. Wrapping in Denso tape was an old trick -  If price was similar I'd go for single leaf every time. Not because of difference in performance but rather the fact they are maintence free. Paul h |

As they'll be new springs, I would still probably refit the 1 inch lowering blocks. The 4 pot cars do have a rear ARB, but it's a smaller diameter...
