Front Droop and Preload

Hi all



following on from some earlier posts of mine on handling of my 2004 VD, I'm doing a bit more research into front droop and preload.



I have got some good feedback from a supplier in the UK regarding setup and was all set to try it out when one of my fellow competitors lost his brakes (literally a pad separated from the backing plate), spun and hit me at the hairpin and bent 3 chassis rails, smashed up pods and radiators, cracked the bellhousing etc etc. You all know the drill.



Anyway, one point I cant seem to get to the bottom of is the guy I've been talking to in the UK about setup says he runs 300lb springs on the front of the cars with 0 droop, but also says he achieves this with no pre load.



I'm only a few years into this car setup game, but am a mechanical engineer, and I can not see how this is physically possible to achieve given the weight of car and driver.



I run 400lb fronts and need about 300lb (about 3/4") preload to get 0 droop.



The only two things I can think of that he may be doing are:



1: measuring 0 droop without taking off the ARB (I measure mine with it off)

2: droop limiting somehow



Any thoughts?



PS I have previously read the various threads here and on DSR forum on 0 droop
