If you plan on racing, I would do some research on previous threads in this regards.
If you just plan on driving the car at regular interstate speeds, I'm thinking you should be ok.
A few here on the forum have mentioned problems with the outer boots clamps breaking/slipping. Some have caused the broken clamp to wrap around the brake line & twisting & braking it. There are others who said that the clamp came loose, expelling black molly lube from the joint & boot.
Having said all that, I had them (after marke axles) on my Z for about a year, untill I purchased a GM boot kit & reinstalled my original Z axles with the new boot kits installed.
Durring the year with the aftermarkets, I had no problems what so ever. I allso didn't race my car durring that time. I would not have had a good feeling racing with after market (Chineese) axles/boots.
