Fitting coil-overs on Monday and wondered how low have people generally gone or did they keep the car around the same as say H&R's springs 30/40mm. Don't want to be eating too many manhole covers lol
Possibly a bit lower, you want to be as low as possible without effecting the quality, it's trail and error to be honest. You will want tad of rake angle wound on too.
As said above, its down to personal preference. The height we initially had ours set at was just too low to not scrape on speedbumps. That was this height:
We had it raised slightly to where we are at now:
Just looking at those 2 pics, the difference doesnt look much (If any) but it now clears all the speedbumps we've thrown at it. However, it does scrape in some multistory carparks.
So I think its just a case of trial and error. Raising and lowering is something anyone can do, so once you get the height right, take it to be geo'd.
