I have been driving my '06 GT 'vert for about a week now since removing the old badly rusted rear braces and having a pair of BMR boxed frame connectors (#SFC011B) welded in. At first I didn't notice much difference except a little tighter feeling on the curves. But after really doing some back road driving, I say the improvement is very noticeable.
Even with almost 124K miles on my pony equipped with GT500 spring mounts, KONI STR.T shocks & struts and Michelin Pilot Super Sport tires and the frame connectors I don't think I have ever driven a better handling car. With this number of miles most convertibles I have had in the past were real rattle traps. This one is still nice & tight.

 

That's good. We own these cars to enjoy them.

Nothing better than blowing off some steam and carving some corners.

 

Good to hear! And also good to hear you drive and enjoy it as it should be. Sounds like it's holding up great with high mileage!
