Hi AcemanToo/Max,
I have'nt experienced the coil binding problem that others have reported, but my supplier took that fact into consideration for the front coil-overs. From the outset I have tried to keep to the origonal specs for the car, and not change the "base line". I made a miss by not measuring the origonal ground clearance figures for the car. But the tyre/wheel arch clearance figures were never has much as 4", mine are 2" at a pinch. (4 fingers for me is 3")
I sent complete examples of the front and back coil-overs with the calculations I had made based on the figures given in the topic and calculations I had made. The figures corresponded roughly with the tests made on the examples I sent to SDV so we went with those figures.
I knew the car had experienced a broken front spring, off-side front if I understand the service invoice correctly, which was replaced in 2011 (both sides) this could have been caused by the coil binding problem reported by other owners. I think the replacements came from Redline. I have checked through the other invoices I have and believe the rears were replaced in 1999 and the fronts replaced in 2001, the invoices refer to shock absorbers so I assume the origonal springs were retained.
To be quite honest the rears looked terrible, with totally "decomposed" bumpstops, very rusty springs and shocks. The springs on the front were in better condition. I now have a completely new set which were built up by SDV "in-house" using H&R sport springs mounted on SDV's own shock absorbers with adjustable lower spring perch and locking collars; they re-cycled the upper-mounts from the Koni shocks I had. They look similar to Dgoose's coil-overs illustrated in "Reply #9 on: June 12, 2014, 13:06:51".
I'll send you (AcemanToo) a copy of the specs I derived from the origonal post sent to my supplier.
As a footnote I also triggered the inertia switch on my Ace last week. took two days to work it out too! I dropped the rear of the car abruptly when releasing the hydraulic jack. So I've also updated the " Non-starting" thread.
