BMR Subframe Connectors
by Jordon Musser
Overview
Although the stock F-body is decently stiff, the shock of strip launches can bend
the unibody. A stiffer chassis is also very noticeable on the street, as the car
will react faster to your inputs. The most popular way to stiffen a F-body car is to add
subframe connectors. There are many manufactures that make them, and after looking around
I decided to go with BMR Sub Frames because of the NO BEND boxed construction. They
are available direct from BMR for $125.
Installation
Although the installation is fairly straight forward, I ran into some problems
because I believe that my car was slightly tweaked to begin with. I had to remove some
material with a grinder to make the passenger side to fit properly, however everything
else went smoothly. Just follow the supplied directions. I bolted mine on, then had them
welded.
On the Street
Although the sub frames did not affect street driving very much, they did make
the car feel a little more rough over bumps, because the chassis does not flex as much.
At the Track
Strip: Because of my lack of horsepower, I did not notice a difference in 60ft
times.. but the car won't flex any more during launch.. should help keep the car straight.
AutoX: The car felt much stiffer during S turns on the track. The car seemed to respond faster to steering/throttle inputs.
Conclusion
I highly recommend this mod, as it makes the car more rigid, and should help prevent a
tweaked chassis down the road. Give BMR a call, you won't be disappointed!!
