Is there any advantage one has over the other?

 

 

I tried a search and couldn't find anything, which seemed odd to me. I'll try again.

 

I hear the Lexan T-tops are prone to warping over time.

 

They are prone to spyder webbing but that is common.Also the weigh about 8 lbs apeice instead of 40!I believe they came in 91 and up f bodys.

 

Yes, they do warp. I want to get some glass ones (glass ones also look a lot better than aged lexan tops). Ever since I bought my car the t-tops had thousands of little tiny 2mm long cracks inside the lexan (you can't feel them from either side) and now the driver side is warping and it whistles at 60+. They still don't leak though.
