thanks for the comment, Steve. To summarise the charts - I went through the range of springs offered by the multi-site online places and Ebay, and where they listed measurements for spring height, spring metal thickness and spring coil diameter, I tabulated these and applied an equation that gives a relative (not absolute) spring rate so that different options can be compared. You can also see the "sport" versions that are typically ~30mm lower than standard in overall height, and other variants from other VAG models that could allow one to raise / lower the car outside standard ranges.
ie - autodoc.co.uk / buycarparts.co.uk / other brands of pkwteile.de and various places on Ebay.
The caveat with the table is that there seems to be not much by way of rational identification by the suppliers of models specific to particular option combinations except for 1.2tdi vs 1.4i vs 1.4tdi/1.6 and sport vs non-sport for these, so everything else is down to a lucky decision and then empirical experience of how it turns out on the car. Ie - some springs state "OSS" / "no OSS" / no air-con etc. but to be honest this annotation is quite haphazard.
Finally - the table is only as good as the data - if the online places or I have mis-copied the numbers (there are one or two springs where I wasn't able to cross-check from independent sources) then the info would be garbage. Also, Monroe and Bilstein springs don't supply the info to the online place so the tables are biased against these companies.
Just based on the numbers in the Ebay link you supplied for the KYB RH5514 (338H / 9.75mm / 108D), on paper these would be right in the ballpark of 1.4i rear springs, standard height, average spring rate etc. so you probably wouldn't go far wrong with these, and the Monroe 3436, although without measurements, is rated for 1.2tdi and 1.4i so probably very similar.
. Apart from that if the axle comes with wheels and drum brakes it would be perfect indeed. i will check with him. Thanks for the suggestion.
