Hi Drew. I had new Kings progressive springs made and fitted to my car in 2005 when I purchased it. Shock absorbers too. The ride is very firm. Could be softer. Handling is awesome. I often joke that it's a sophisticated go-cart! If you don't have a car in mind, mine is for sale at the moment - though I haven't advertised it yet. If you live in NSW, it is a pain getting it registered if it isn't already registered in NSW. Mine is fully engineered and has been on NSW registration since 2005 - so no problem there. The price is right at $12,000!
