Coupe or Convertible. Which is stiffer?

Did the MM Subs make a big night & day difference in your vert? Did it feel like it made the car new again?

Yeah, it was a completely different car. My wife rarely drives my car, but she recognized it was different almost immeadiately. All of the twisting and flexing is gone. :nice:
 
Stock for stock, the coupe wins in stiffness. I've never had my 2000 top leak, and with the Griggs subframes, MM STB, and 4 pt rollbar, I'd have to say that ...
Coupe is stiffer no matter what you do to the vert, except if you weld on a hard top... and even then the coupe will be stiffer...
is not quite true, because I've rode in a few coupes, and they're slushy compared to my stiffy (vert) :D But stock was a different story...
 
Hey for you guys still looking for a good sub frame kit, check this out. The company is relatively new to the modding scene but they have brilliant engineers who are thinking outside the box with some of their products.

Their customer service is above and beyond that of even the best other online vendors.

Here's their subframe kit. $275 sounds like a lot but the quality is awesome and you get a free ds safety loop and clearance for side exhausts!

Think about this way...the Mustang has unibody construction (i.e the body and chassis are integrated), so chopping off the top to make a convertible is like removing a big part of the bracing stucture.

If the Mustang were body-on-frame, the difference between coupe and vert wouldn't be as dramatic...
