Thinking about lowering my W108 Mercedes

[Raarasutra]

I recently purchased a mint 1966 250s with 61K original miles (see pict below). I love the car but I can only assume the 11" of ground clearance was a design necessity in the 60s when you routinely needed to transport 5 large Germans and their luggage, while driving over bad roads, in winter, with snow chains on, going uphill both ways.

I laughed so hard. You win

Also, if you look at the springs themselves they have one end that is pigtail (don't cut that end) and the other is tangential (spins off into space). At least according to Eaton Detroit Springs (guys who've made springs for 100 years) they are okay to cut: read this: http://www.eatondetroitspring.com/cutting-coil-springs/

Yes, they will make the spring stiffer but that is needed given the car sits lower to the ground; you want it stiffer so you don't bottom out all the time. When you have custom lowered springs made, they are stiffer than the stock ones - suprise suprise.

Hope this helps everyone.
