Goldie as Joe says i have the gaz rear springs similar to the ss springs but they are slightly softer.
Car may sit slightly lower but not much in it.
Look a few posts back fraser has swapped from gaz rear springs back to ss. We didnt have the ss coversion so i cant compare.
Very happy with the way the car sits now, got the front end dropped lower, the front splitter will pay testament to that
