Speed Speed axles are Drive Shaft Shop Axles (DSS) and they are just a reseller. I already had DSS axles and they were ok for a year or so and then started “clicking” in the drivers side CV boot. Both of my buddies R53’s with them did the same thing and we all upgraded to the RMW ones we all have not had a problems since.
We all have R53’s and go to the Dragon and drive our cars hard that week. Only one of my friends drives his car daily and he has had no problems. He is our test guy since he puts a ton of miles on his car weekly / yearly.
