I've altered the springs on mine as I was getting the springs going coilbound (free space between the coils is fully used and the coils touch, which causes horrible bangs). It was going coilbound because I had wound the platforms up to try and maintain the correct ride height when more than just me in the car. With the original 100lb 12" springs it was ok with just me in the car and no luggage, but any more weight and it was going coilbound. I also experienced horrible pitching motion on some concrete roads due to the differences in the rates front to back. After weighing each corner of the car (sprung and unsprung plus including for driver/passenger weight) and calculating the suspension leverage ratios, I've now got the rear much closer to the rate of the front. This was done by fitting 140lb 10.5" springs. It has got rid of the pitching and coilbind and the ride is much better when more than just me, although its a bit stiff with just me in. When I get round to it I'm going to try 130lb to see the difference. I recommend Faulkners springs, they are what a lot of people use, and you can get direct from them which is cheaper than through Merlin, etc http://www.dfaulknersprings.co.uk
