I got my SFC's welded on yesterday and I got on it tonight. The car seems like it is getting much more power to the ground, when I get down on it the car seems to be breaking the tires loose a lot more. I dont know if its just in my head, or if maybe they are helping me get more power to the ground. Whether they are or not, the car feels a lot sturdier and I am very pleased with the results.

 

What type did you end up getting? How much did it cost to get installed?

 

After installing them in my car, to me it "felt" like the suspension was being worked more, and the "car" was no longer taking the bumps . I'm with you, I don't know if it's in my head or if it's legitimate, but I think that's the point of the SFC's ... make the car more rigid and stop wasting energy flexing the car .

 

It was definitely a night and day difference after having mine welded on. The car did feel alot more rigid and all of the annoying creaks/rattles finally went away.

 

i know my car felt like the ride got rougher after the sfc install. i attributed it to the car flexing less, and the 50K mile suspension suffering to take up the slack.

i live in the land of bridges (42 over the course of 105miles) and as i go over the seams of the bridge...that make the car dip a bit...it felt much more solid. particularly at higher speeds.

 

Yeah, the only thing I can figure is the chassis is flexing less and letting more power get to the ground. I know many people will probably call bs on this, but like I said it may just be in my head.

I bought the SFCs from J&M Products for 130. They are a vendor on here, they cost about $100 to have welded on. I had heard so many horror stories of people fuel lines catching on fire so I wrapped my lines in foil and sprayed them with water the entire time he was welding on them.

Only people will call you on this subject are the ones who don't have SFC's installed on their car. My opinion is they are the best investment you can make---Welded in Sub Frame Connectors.

 

Here's a question: Has anybody welded in SFC's that were originally bolt-in? Just curious if there'd be much advantage/improvement over simply bolted-in SFC's? (can you guess which type I've got? )

 

My guess is you have the bolt in SFC's and there is no problem getting those welded in for better results (less flex & wear on fasteners).

 

I've heard it makes a pretty noticeable difference. I got the weld on's (BMR boxed) and really like them.

I think the original poster is feeling a "pseudo throttle response" improvement since the power is applied to the wheels more directly via less flex. I couldn't tell you because I had so many other things done to mine at the same time, it was like a whole different car when I got it back

 

Capn Pete: I'm pretty sure SLP weld-on and bolt-in SFCs are the same piece, except that the bolt-in version comes already powdercoated black. I've never used bolt-ins, but I do love my weld-on SFCs

 

Ive got a friend with bolt ins that he had welded. He just did it to try and keep wear on his fasteners down.

 

Where did you get yours welded in? I have an exhaust shop down the road willing to weld mine in for 50$.

 

Thats a good price. Let them do it.

 

That is a very good price. I just went to a local muffler shop.
