No, I'm not asking which is the cabrio.

In terms of rigidity and power handling, how comparable are the two? Can an R57 handle the same amount of power and suspension mods as the hardtop?

If year matters, I'm curious about the 2010.

 

The engine and trans are the same, so I would take that to mean that anything that would work with the hardtop would work with the cabrio. I'm also pretty sure that the suspensions are the same. My understanding is that the cabrio has additional bracing under the door sills and in the windscreen to stiffen the body and account for the lack of a roof.

 

Thanks. What I want to avoid is some unspoken rule that you don't put more than X power or Y set of suspension mods into a convertible.

 

As far as my experience and the experience of everyone I have ever talked to, hard tops ALWAYS handle better than convertibles, the roof creates a more rigid body structure.

You can still use all the same type of suspension mods, but the convertible will never handle quite as will as the hard top.

 

^^ This is true. A hardtop is nearly always more rigid than a convertible.

 

True, and wholly understood. As long as there's no, "If you do this to that car, it will break" kinda thing.

I just remember the GNX of old, which as a hardtop, still had enough torque to twist it's own frame into a pretzel.

 

Don't forget to post pics of your mods when you do them!

 

Unless you are referring to a Ferrari 458. Even the Porsche Boxster compared to it's Cayman sibling is negligibly less stiff. But, for most other cars, then your rule does apply.

My understanding is the R57s will take the same mods as the R56s, with minor exceptions for fit of exhaust where the additional bracing on the R57 will interfere. As far as power , suspension Eric they gave the same limits.

Agreed that the R57 might be a little more flexible, but when I've had loaners the difference seems negligible.
