Hi Peter, many thanks for taking the time to answer, after stripping down he rear of the car, yes i'm sure it's the rear shock, as switched sides and the click re appeared on the other side. Checked every bush and every moveable part. The last resort was to swap sides and he presto there it was.Seems to eminate from the top of the unit.
As of yet have not found a UK supplier listing Koni's to fit a 328, my one is a late model ABS (89).
Checked with fastboys web site ( thank you ) but couldn't find anything suitable there either.
My intention was to replace both front and rears as well as bushes all round this winter, to tighten the old girl up !
But it seems to be at quite a price !
Thanks Gavin.:crazy:
That's good to hear you've positively identified and isolated the noise and narrowed it down to the shock.
The difference between the yellows and reds are that the yellows are adjustable.
The US spec 328 GTS DID indeed come with Koni shocks.
I found the models that Peter posted here in the US for $145.53 from eshocks.com

That sounds too good to be true! I just checked Koni's North American website and they don't list anything for Ferrari after 1985 and I know after checking my own car, they want a small fortune for a pair for the 308 GT4 and only the fronts are available!!
That doesn't mean they didn't make them for the 328 originally, but that even THEY don't have them available currently.
That's why when I started my suspension rebuild project earlier this year, I had no choice but to rebuild/restore the ones I had. Thank goodness Koni used a non-pressurised design and they truly are rebuildable. Except for a couple of specialised - but commonly available - tools (spring compressor, pin-spanners), I was able to do it on my own. Oddly enough, these use basic, standard hydraulic seals and O-Rings sized in inches, not metric. Everything was off-the-shelf. As indicated in that 328 pdf file posted, the oil used is standard hydraulic AW/ISO32 oil.
Gavin, I hate to break it to you, but nothing is cheap with these cars! As mentioned earlier, you may have to have your current shocks rebuilt and at that price you quoted, sounds reasonable to me. Just make sure they're experienced... Downtime is unavoidable! My car has been off the road now for almost a year...
As for the Bilstein shocks that are currently on your car, I seem to vaguely remember some mention of them being used on the 328, although all of these Koni references - including mine! - seem to contradict this! I wouldn't be surprised, or put it past Ferrari for equiping a small batch of 328's with them. They are a business like any other and for whatever reason (like a delay with Koni producing shocks, or maybe Bilstein undercut them to get some business!), a few cars were probably equiped with them. They used GM Delco alternators for the 348 because they got them cheap and we all know how that turned out (failures and thus, the recall and Nippondenso replacements), Pirelli's delay with tires and a small batch of F40's wore Bridgestones instead. Etc...
