My P5B coupe has a pair of Wadhams' rear springs fitted. I fitted them 7 years ago. They are the 5-leaf 'heavy duty' type and, as has been discussed on here many times, the rear ride height is too high.
I don't want to go to the expense of buying the newer 7-leaf springs in order to lower the back end a little, so I thought about lowering(?) blocks and longer u-bolts. These are available on Ebay for Escorts and Capris and so-on for about £30 a set.
Does anyone know of a supplier of suitable ones that will fit a P5?

Any generic set will do as long as the U Bolts are the right size and they have the correct locating profile etc.

Well Vince, I called them lowering blocks when I posted this initially. Then I thought, the axle is actually being raised in relation to the body and the springs, so I amended the post......  I suppose that they are really body lowering blocks! |

My only concern in using generic blocks would be that the springs on the rover are quite wide compared to the early fords.
It wouldn't take much for an engineering firm to manufacture a bespoke set for you though.

That was my concern too. I was hoping that I would be able to get an off-the-shelf kit that fits a P5, but I was probably being optimistic. I was trying to avoid partially dismantling one side to get the measurements and then putting it back together to drive the car back into the garage until I could have the blocks made.
I'll just have to bite the bullet!

I have the same dilemma, but I'm thinking of taking one of the leafs out of each spring instead.

These Polyair suspension looks very interesting. I am using additional air suspension cushions on my I've come camper and it solves the problem of bumping through the spring blades. I had the same problem on my Morris Minor, could not find suitable air suspension units to fit between the blade and body. I don't have the probkem on my P5, but if you do, I wonder I'd there a reason not to use air suspension units as Polyair is offering? Looking for opinions! Frans |

Thanks Vince, that looks great, but I'm looking for a simple solution....  |

I have the same dilemma, but I'm thinking of taking one of the leafs out of each spring instead. I've thought about doing that, but I'm concerned that one leaf taken out from five may give too much drop and strain the contrasonics. I read somewhere on here that using the largest leaf from a Wadham's spring in place of the same leaf on a standard spring would rejuvenate tired originals. Unfortunately, I don't have any original springs I can try this with. Also, lowering blocks are probably the easiest solution. |

Just a thought. I can measure the overall size of lowering blocks I would need without dismantling anything, but I need some help with one thing: Does anyone have a rear leaf spring lying around? I would be grateful if someone could let me know the diameter of the locating 'dowel' (from memory, I thinks it's a kind of extended cup washer under the head of the central bolt which holds the leaves together.) It would save me a lot of work! |
