I'm looking to get some lowering springs, what would be the best ones for comfort (keeping price to the minimum) i know for vectras its pi and i had them on mine and was impressed, jamex are nice and cheap, any good? Also how low can i go not to have any problems with speedbumps, again on my vec it was 40mm lowered with rieger front splitter and no issues, would 40mm be same on astra or should i go for 30mm! Is my W reg Sri 1.8 20mm lower than standard?????
All help appreciated!
