subframe connectors?
subframe connectors? i'm looking to buy some subframe connectors for the camaro in a few weeks and was wondering what the benefits are of having 3-pt connectors over a 2-pt? and why is chrome moly cost so much more?
Heres a opinion The difference between a 3-pt and a 2-pt is just think of a 3-pt like a (roll cage) sturdy wise for underneath your vehicle it gives you a great mounting point for your torque arm and overall eliminates body roll. The 2-pt will give you the same features when it comes to stiffening the chassis. And when it comes to the chrome-moly it cost so much more because the chrome moly material is more expensive to purchase and takes quite a bit more time to weld. The chrome moly versions require all TIG welding which increases the production time, the weight savings is 4lbs. But when it comes down to it what matters is......What do you plan on doing with your vehicle? Is it going to see a lot of track time?....or is it a daily driver? And how do you want it to perform in the long run? If you have any other question feel free to ask and I will be more than glad to help.
Thanks
Brad

The strength from chromoly comes from the material that goes into the production of the molten steel. Chromoly is steel with chromium and molybdenum (among other things) in the mixture. You dont just put mild steel in an oven and out comes chromoly.
Chromoly is stronger than normal steel, weight for weight. But the reason chromoly parts tend to be lighter because you can use thinner wall material and have the same strength as mild steel.
Also about the 2 and 3 point debate, if youre drag racing the car we have many low 8 second cars with our 2 point SFCs and they have no complaints......

Jay-bird.... I edited my answer BEFORE you posted... maybe read my edited response before you post. I worded my answer wrong and corrected myself before you posted.
Next time pay closer attention

On a side note... Chrome Moly material is designed to be heat treated and this is what I meant. Never once did I say you put mild steel in a oven and out comes Chrome Moly.
Yeah but not before I quoted it. Hence the ninja edit comment. 
So then moly cages in cars get put in big ovens and treated as well? Get real.
To the OP sorry about the clutter in the thread, just trying to keep the information correct.

Brad is correct, 4140 and 4130 materials are designed to be heat treated... he didn't say they had to be or they are. The make up of chrome moly material is that of a heat treatable item, when heat treated you increase the tensile and yield strength. We do heat treat our adjusters we use which are machined from 4140 material... this is where Brad got confused and caught himself. We also use heat treated chrome moly rod ends in our products. We do not heat treat our products but if the applications required it they could be heat treated.
If you want to discuss material grades any further just let me know. Thank you

My car has the connectors, and even with 400+ rwhp has no wrinkles.
That is possible. If you buy the concept of connecting the subframes, which I do, then you have just tightened up the entire chassis. If your car was already as loose as Suzy Holdem Open at the class dance, then you may only lessen the effect.

Do a search, even if the dimples are from flex, SFC's couldn't do anything about it because they don't brace the chassis that far back. There are just as many people with SFC's that have dimples after installing the SFC's, than there is people without SFC's and no dimples.
Now getting OEM replacement or over the counter shocks at autozone are not going to do any good, you need quality shocks with good valving to get the job done. My car is lowered and has much larger swaybars than stock yet no interior noises to speak of because the shocks are doing their job and not letting the vibrations get to the chassis in the first place.
SFC's do not reduce body roll, that's the job of the swaybars and springs.

Combined this is commonly misinterpreted as "chassis flex" because when you are accelerating or launching the front feels like its "flexing" compared to the rear when in reality its the front is just floating while the rear is overly stiff.

Please note, shocks may be part of the solution. But they are not an end all, do all solution. Merely a part.
