Had my check done at Centre Gravity -
Very informative - everything within tolerance and very tidy for a 98 with 130k miles. Given it's a Cat C and it turns out it's already had the Gundo hack done on the aftermarket stainless exhausts. It has had new Porsche parts used on rear left axle so assuming that was the main source of the Cat C although a new Boxster bonnet implies something happened there. It has original front suspension, wing and rear arch although there is a slight bit of filler used but looks like a very light Cat C so I'm thinking it was a rear wheel sideways to the kerb damaging the suspension and sill or similar.
Needs very little doing as it's been well done aside from 1 iffy rear arm (Coffin arm? TCA? Wishbone? It's the bigger one that was single sleeved originally but is now double braced to strengthen it) that apparently Porsche replaced because it was weak.
Oh and they said a couple of problems such as ride height would be just down to having the roof on because of the weight as an extra 100kg or something. The rear shock that is leaking is within tolerance however it is 5mm lower than the left. After 8 months of leaking I am surprised it was that good!
Was really interesting to look around the car as I like to work on my cars and an ex-racer so nosy. He said someone had spent a lot of money maintaining the car.
Slight bit of toeing so just needs a geometry setup once new rear shocks are fitted and a new arm for the right rear.
At least the wheel bearings are ok after I got a little sideways on the power out of a junction when it was starting to ice up and the left rear has a scuff on it now where I think I may have kissed the kerb before fishtailing up the road.
