^^^thats dodgey as fook. no way would i recommend that. if that slips out with the spring compressed it will take your head off.
also the spring compressor method i tried (seemed the easiest option to me at the time) but there wasnt enough room to get the compressors in on my car.
when i did mine the subframe was lowered. its only on 4 bolts IIRC
another way is to take off the lower arm bolts but on mine they looked a bit rusty so didnt want to disturb them in case they seized on.
in the end renault main dealer did mine for £110 as the quoted me the price of a normal clio (2hr labour)
took them 5 hours in the end!
