Front suspension was rebuilt with stronger tubular wishbones from Grantura Eng. . New ball joints and a set of double adjustable AVO shockers. As the intended use of the Griff was to include trackdays the suspension was built using Polybush inserts.
Having to replace the complete exhaust manifold system meant I was not only able to upgrade to the later clamp type headers, but also treat myself to a lovely new Clive Ford Cat less Y piece. Shiney !
The later style manifold headers are not a straight forward swap though, additional clearance is required between header and bodywork (fibreglass burns well !) so additional cutouts were required in the footwell areas and as an added precaution the headers were wrapped in heat shield material to keep under bonnet temperatures down.
Once the mechanicals were all sorted off it went to a local fibreglassing geru for a new nose. However, the 500 nose (chosen for improved air flow for the track work) did not suit the pre-cat Griff and as the headlights were to receive some attention anyway, it was decided to remove the mainbeam light mountings and the central rib, and close up the air intake slightly.
The intention here was to still maintain a larger air intake over the original pre-cat nose to give better cooling on track, but to lose the main beam lights from the opening. The image gives you some idea of how wide the original 500 intake was.
Projector style headlamp conversion allowed both beams to be accomodated in the light pods that usually only housed the dipped beam lights. (More on that later).
The mods leave the front grill area less cluttered and also (un-intentionally) gives the Griff a bit of a 60's ferrari look about it ! Once the number plate goes back on though, that will change but the larger vent will certainly help with cooling.
Of course the original design involved a lip spoiler and intake vent aperture underneath the front of the car, but ground clearance issues prevent a larger spoiler being fitted, hence the wider mouth on the 500 series cars. What we have here is a half way house between the two.
Finally back on the road after a good few months in the Barn.
Off to Mat Smiths Sports Cars for a 6k service, 4 wheel computer alignment, suspension set up, general check over, tune and MoT by the big man himself.
Road and track, here we come !!
