Subframe connectors, worth it? Do subframe connectors really help that much?
With two pieces of metal running front to back on each side of the car, how does that keep the chassis from twisting/flexing? It seems that you would need braces/supports running side to side as well.

I installed them because of a crease in my RR quarter from launching. It hasn't come back, though I still get dimples on the tops of my quarters.
The penalty was a huge increase in impact harshness. After installing them, I could feel every pebble on rough road surfaces. Had I to do it over again, I wouldn't have them welded in.

i think mine look great...if your going to do any harsh driving get the SFCs ull thank us when your quarters dont have dents in them....i bought mine from eric at midwest chassis and he made them chromoly 2 point for me becuase they are they are lighter and stronger than the mild steel...i wouldnt go with 3 point because of the weight and i dont see you needing side to side support but thats my my opinion...
not really in harshness no but im lowered so its already somewhat harsh but the SFC's didnt make it any worse at all that i could tell anyway.. but makes the car a lot more solid in all aspects and handles better too
This topic has been covered numerous times.
The first thing you should do to your suspension is shocks and springs. And by shocks I mean a Koni/ strano setup.
I used to think I needed SFC's until I talked to Sam strano who set me straight on the theory behind SFC's.
If you have a worn car that noticeably flexes then yes by all means get them. But if you're running stock suspension it is NOT your chassis flexing, it is the inability of your DeCarbons and springs to properly control and dampen the car.
why would you try to stiffen one of the most rigid sports car frames?
the 4th gen does not body flex like the 3rd gens.
I'm telling you. do Shocks and springs first. THEN decide if you need SFC's
BY NO MEANS should this be your first suspension mod.
Furthermore, if you do have an aftermarket suspension that is setup incorrectly, ie.. springs and shocks not functioning together and/or are poor quality. THAT is where you need to start.
SFC's are a placebo mod, and if they do stiffen it up at all (unlikely) it's going to be minimal, and the noticed impact harshness will result because you do not have a good set of springs and shocks.... which is where you should've started anyway lol.
Thought I'd give you some advice... I'm fairly certain I have Strano's backing on this.

I don't think my car is considered worn out by any means. But there has to be some flexing going on in the rear end to create creases/dimples in my sheet metal.
