I am very seriously looking at buying some subframe connectors. I was looking mostly at the kenny brown double diamond. I plan to use the car for mostly daily driving and monthly open track events.

My question is has anyone used the kbdd with dual exhaust I was wondering if they might cause some fitment issues. because of their size I will also be getting a 4 pt roll bar as it is a convertible and I have to have one to run at these track events. I wondering if by using a regular sfc and the roll bar that will tie the frame up well.

Thanks

 

If you're putting a good rollbar into the car I'd say just a normal front to rear subframe connector (2 pt.) would work just fine. The rollbar will strengthen your frame laterally in much the same way as the triangulation of the KBSFCs, and most likely better.
