Subframes-Worth it?
Subframes-Worth it? Well after doin a little reading and checking around I am unsure if I want to install my subframe connectors. I have a set of SLP Bolt in that I got for a good price, and I noticed they will add a little weight to the car, I plan on supercharging my car and know that it would be a good idea to have them but should I wait to install them, I have minor mods nothing to big so are they needed or will it just be added weight?
There are literally dozens of multi-page threads on this topic. Search is your friend.
I took them off my to-do list. I'll worry about it AFTER the suspension is completely done, if the need for them arises.

I have them. SLP bolt-in SFCs. I bought them right at SLP in Toms River, NJ from a head shop manager. I am not impressed. I did not notice a huge difference. In fact some of the diferences I think I might feel, are just in my head because I installed them and I expect a difference. Upon, installing them myself, I came to find out that my chassis seems twisted. I couple of the holes where the SFCs connect to the tunnel brace, didnt line up perfectly. I DID have to slightly drill out one hole to make them fit. I tightened down every bolt that CAME WITH the SFCs as hard as I could, since they give no torque specs. And also used blue thread locker on all of those. The 4 bolts where the tunnel brace is, have a fairly fine thread, so I was worried about tightening them too much. I did not use thread locker on those, and I will be checking on their tighteness tomorrow. Possible taking them out and putting thread locker on them as well. The LCA bolts are, well, snug. I did not notice a huge difference, my t-tops still rattle, and most bumps still seem to be felt throughout the whole car. I am seriously considering taking them off and selling them.

I have the UMI bolt-in SFCs and they really did make a difference in my car. They definitely tightened up the whole car an eliminated some rattles and squeaks. The most noticeable thing for me is that when you go around a turn it feels like the whole car is turning at once instead of the front going through the turn followed a second later by the rear.

I noticed a diff. when my BMR SFCs were welded on. Then again I had stock suspension at the time. I'm considering taking it off when I finish my suspension to see if i notice a difference, but that wont be for a long while.

I believe its worth it. But I too have the weld in ones, from spohn. After installation my car felt very solid. Before the weld-ins my car had a very loose feel to it, it didn't seem to be planted to the ground. After weld-ins, the car feels very stable. When launching the car, it stays straight and true, also it helps to prevent wrinkles in the rear quarter panels if your car sees any track time. Although the steering wheel now has a heavy feel to it, the benefits of the sfc out weigh the added weight.
Today I installed a set of bolt in SFC's. My first impressions were the car felt stiffer. Not a huge difference, but now when I drive over bumps the whole car doesnt rattle. Dont get me wrong, it wasnt like I drove around and thought, man this is a totally different driving car. They do their job, but dont expect to feel like your driving a newer car. All in all, Im happy with them
I have a popular boxed type weld in. No difference in my opinion. It does have more vibrations and road feel. Stiffer=more interior rattling over bumps etc.
I wasn't impressed. Plus it's developed more body wrinkles after they were installed.

I usually chime in on these SFC threads to warn guys from my own experience. Yes, they made my car feel tighter, but at the price of a much harsher ride. I had to get Bilstein shocks to mitigate the harshness and so it proved to be a very expensive mod. SFC's are the only mod I've done to my car that I regretted afterwards.
I don't feel as passionately about this as I used 2. I did bolt-on SLP SFCs as one of my 1st mods. I think the ride was harsher, and I bottomed them out on a driveway (SLPS hand LOW!-you can see them uneder my car in the sig pic). So I took them off and sold them after more research and my personal experience.
Its hard to realy measure how well/if they work.
What I know for sure is:
1-they make the car heavier
2-they make your wallet lighter
I wouldn't go as far as to call them worthless, but I think your mod $ is much better spent elsewhere.
