sub frames, do they really work?

scorp69 · Sep 8, 2004

not all sub frames are created equal. you get what you pay for. I know. I had kenny brown in my lx and they were that great. I just installed some custom ones from a local shop on my 84 svo and could notice a big difference. the car was driving straight for the first time. i just need to take it down the rough roads for the final test. also, depending on the sub, welding isn't cheap. some things aren't worth doing in the back yard. again, you get what you pay for.

do them, wether you buy them or get custom ones made, get them done and do it as soon as possible. Also, weld them or have them welded in, dont waste your time or money with bolt-ins, although I bolted and welded mine in, then welded the bolts....

get em, i'm getting mine welded in here soon....glad to hear all the good things about them

Why are you laughing at that? 11-17 year old STOCK mustangs are mostly twisted from the torque of a stock motor. Unibody's are weak, your an ignorant tool for that comment.

I agree, not much power. But after a couple launches on slicks my door wasn't opening and closing like it used to, so I figured I'd better do the sfc's.

Actually, I have to agree with the above two comments (although I may not have been so harsh in my reply ) It doesn't take much to twist a stock fox body. Even less when the car's got a few years worth of rust on it and the metal has fatigued. Besides it’s not only torque that twist the chassis. These cars are amongst the worst riding I’ve ever been in and you can only transfer every feeling of every pebble, crack and bump in the road through its chassis so many times before things start to give. I've even seen a couple of windshield pillars and windshields crack over time from the body flex.

Stiffening the chassis up give the suspension the chance to do its job properly, without absorbing half of the shock through the rest of the body.

what are in floors, are those the kind where you have to make a tunnel in the back seat floorboard to put them in because mine had these when i got it and you can see the square tubing or whatever through the holes in the stock frame, do you get what i mean.

That's the stuff. Griggs Racing sells a kit. I'm going to get some custom ones put it, but same end result

Even going straight on uneven roads, you'll notice the difference. I'm used to my SFCs already, time for some In-floors

You talking about these runningmole

dastang2 · Sep 9, 2004

that is what i got i guess but i only have the humps in the back seat and not the front the front part of the floorboard, what's up with that.

Why are the bolt on ones so different?

scorp69 · Sep 9, 2004

runningmole. since you're in san diego, call grc performance in mission viejo. they have full length custom subs. just got mine put in my 84 svo and its night and day. still need some in my cobra. it'll be around $300 or so for everything. the subs are really good. better than MM if I dare say.

The bolt on ones work themselves loose all the time and never do as good a jo (even tight) as welded in ones. Which ever set you buy...welding them in should be your only option.

I have crappy UPR subs, and they still helped a lot. Tightened a lot of squeaks and rattles, and made me feel the gross inadequacy of my stock suspension. Good thing I've got the Bilsteins half in (haven't done the rears yet), the car feels totally different.

Is this what you have? Its the same thing just has carpet over it. The front of it has a slight raise. Maybe 1/4 inch.

I was gonna get the full length MM subs. So GRCs are better in what way? How long did it take them to install the SFCs? Any pix?

Zmann · Sep 10, 2004

The stock body twist more than you know!! The right way to do them is through the floor from the fire wall to the rear bulk head!

Like this!

scorp69 · Sep 10, 2004

the grc ones are more stout looking. mm are good also, but I think the grc are better, even though i have never used mm subs, but have used other parts. call umberto at grc and tell him carlos(i get no discounts for this) told you about them. he can give you the full specs. its about $150 to install.

dastang2 · Sep 10, 2004

yes that is what i have and my carpet is tightly around them too.

Subframe connectors are absolutely worth it. Cost goes from $22 plus welding wire for my homemades, to $100 plus welding cost for the Steeda's I put on the earlier car, on up. Depends on your level of self involvement. Anything under $200 for turnkey is reasonable.

There are some differences, more is better, and the braces under the seat bolts are well worth it.

I would not worry so much about the cost, the benefits are worth it.

CManT1914 · Sep 10, 2004

I haven't read the whole post, sorry if this has already been asked. But how do the Kenny Brown's stack up against Steeda and Maximum Motorsport's setups? They do have the seat supports correct?

sub frames, do they really work?
