Have a few questions about adding a hard top to my ///M Roadster. LARRY,

1) Does it increase (or seem to!) structural rigidity of the vehicle any? Seems to add to rigidity. Key word here being, "seems."

2) Does the car feel more 'solid' with it on?
Per question #1, yes.

3) Easy to take on and off?

It's a two person job, but you can put it on or take it off in less than 5 min.

4) How hard would it be to DIY? Anyone done it? Don't know, bought mine with the HT.

Thanks!

Larry
