what's the main difference between the Rayspeed springs vs old Pro spring to new Pro springs.
I was getting ready to order a full set of springs and wanted to buy the right type.
mostly racing rubber 13.5.
Thank to everyone for keeping this thread alive.
Old pro springs are short. Around 22mm long.
Rayspeed springs and new pro springs are longer. Around 25mm long.
Now I beleive that the longer springs make the car feel a little "smoother", less "snappy", hard to define but just one of those things.
To get the correct ride height on some cars using the long springs you need the Rayspeed offset bottoms also.
