Some vogtland springs. They are nice purple colour. They were also much softer than the porsche springs in that standing on one and bouncing my weight I could bottom it out. Whereas the porsche ones I could barely move them. On the car, it didnt feel a lot different, but the low ride height made me worry about speed bumps, so they lasted a week and I took them off. On the plus side I am pretty quick at changing springs over now.
