Fitting a Hoyle independent
rear suspension upgrade on an RV8
Steve Newton at Clive Wheatley mgv8parts has fitted a number
of Hoyle rear suspension upgrade kits and provides an outline
of what is involved. (Nov 09)
The key feature of the ingenious Hoyle independent rear suspension
upgrade, designed and supplied by John Hoyle, is it bolts directly
on to existing mounting points on an RV8 or MGB bodyshell. Hoyle
supplies the subframe assembly, special short half shafts and
drive flanges with the MG stud pattern. He can also supply the
Sierra differential, hubs, CV joints and disc brakes with new
alloy callipers.
As the Factory specification for the RV8 included a Quaife differential
most enthusiasts go for a Ford Sierra limited slip differential.
Most of the Ford parts are supplied new and the differentials
are re-built to "as new" condition. Clive Wheatley
says "if you decide to find your own differential then
do doublecheck the diff ratio before buying a Sierra unit although
it is safer if John Hoyle supplies it." The subsequent
sale of the original RV8 back axle as a complete unit can generate
a useful sum which can partly offset the cost of the Hoyle upgrade.

Deciding on
whether to go for a Hoyle upgrade on an RV8 needs careful consideration
as it is quite an investment - including the kit, new Ford parts
and just over two days labour it is probably just under £5,000
but offsetting the proceeds of selling the original RV8 axle
as a complete item could reduce the investment to just under
£4,000. So it likely to appeal to RV8 enthusiasts who
tour with the car in the UK and in Mainland Europe. With a reasonable
annual mileage and the pleasure derived from the improved comfort
with the installation, it is this type of enthusiast who will
seriously consider taking the plunge and "going for a Hoyle".
