OFNA 13mm Big Bore Shock Spring Set (Blue - Hard) (4)
These are definitely worth the price, they're lush and firm but not TOO firm. I've bought these with the Losi front and Rear spring sets (8) and "Losi Front and Rear Shock Spring Set (4) (Gold–Firm) (Ten-T)" and these are by far my number one choice, they're a little more firm then the springs I listed above which is what I was looking for. However I wouldn't say these are TOO firm. These are longer in length then springs I mentioned and I'd say they're all 13mm Big Bores. Just buy it.
