some guy just told me they crack. How safe are they?

 

I use them all the time and so far no problems.
I'd also go ahead and use a floor jack or jack stands if your nervous.

 

I'd like the ramps because the jacks and stands make me nervous as hell on this damn unibody car. With my Jeep, jacks and stands are no sweat.

 

I've had mine for about 1-2 years now and use them all the time. I haven't seen any signs of wear or cracking.

 

my only problem with them.. and i don't think they are rhino ramps. just some ones one got at autozone.. but they don't grip the ground to well when i'm trying to get up on them. they sometimes slide forward.. but it might just be the crappy ground out here with rocks on it. that any my rear brakes not doing their job.. but other then that, the ramps are awsome..

 

There was a thread about them on corvetteforum last year and many people loved them. The only complaint I remember is that if you leave the car up on those ramps for a week or two they start to warp a little.

 

i have used the ramps and yes, they will slide if your not careful. I personally jsut slip some stands under the axle tubes and front control arms to avoid damage to the sub frame rails.

 

i want to put the stands under the rear axle tubes.. but the brake lines are in the way (on the bottom).. are urs like that too??

 

i think the e- cable rund there for a bit... cant remember. i just put the stands in between the space whre the lower control arms bolt up to the axle and the wheels. That seems to work
