these are no better than other rc shocks, and worse than most. horrible spring rate, poor crawling performance. they are extremely stiff and after 3 tries to tune them I've given up. I can't believe I paid this much for a product that is as horrible as these.
they are junk, stiff, very difficult (or impossible) to tune. but they look great, perfect for a shelf queen if i had one.
product is good..but hat to pay tax
