er, kind of a late response but I think what he meant was that it would hurt you because you might be in one class which you're competitive in, but adding SFCs will move you up into a higher class (faster/better handling cars) which could hurt your chances of competing.

as a road racer/autoxer, thats true.

also, an adj. PHB does NOTHING for launching or handling. its to re-center the rear end after lowering the car. if you put new shocks/springs on, then youll need it. if you plan on doing it later on, then still get the adj. PHB so you can align the rear later. it does nothing for drag racing, other then making sure the rear is lined up.

The only differance is that maybe some noise may be transmitted. Nothing that cant be tolerated by the loyal fbody guy.

They will make the suspension do its job instead of allowing body flex to contribute. That means, among other things, you will feel just how bad stock shocks are.

Wouldn't this be what you want? I mean stiffening up the car is the goal. So do the bolt in's allow more flex? Which ones are better? thanks

Thumbs up SFC's good idea no matter what type you get
Hello,
They are both equal in strength! It just all depends on what you have access to! If you have a welder....go with the weld on! If not The bolt on are just a good. If you have any other questions I will be glad to help!

Thanks again!
Brad

Correct, I don't think you can tell the difference whether they are bolt in or welding, boxed or tubular. The bolt in SFC is the same SFC as the weld in it just includes hardware and brackets to make them 100% bolt in. If you do have welding capability this will be better in the long run since there is no bolts to every come loose.

Hope that helps!

Got the BMR boxed, Noticed the difference right away, I am more of a corner carver not a drag racer but was still money well spent in my case.

The 3-Point SFC's will work just fine with that set-up and there will be no clearance issues with the TSP true duals.

If I can help anymore please ask. Thank you!

I'm not sure if welding in your SFC's can cure your manhood problems
