common sense would tell most people that you want the frame welded how the car sits on the ground. if its on jackstands, its gonna put pressure on the frame when you lower it, which is not good.
Even jackstands at all 4 corners is NOT going to make a difference dude Your just being redicliously cautious Seriously they aren't going to tweak around

Oh I agree, that's why mine was done with a lift Im just saying, it's not going to be HORRIBLY CRITICAL if you HAVE to use jack stands or some $hit

Yea I had mine installed for 100 bucks and there was no need for a drive on lift... they used a regular lift and it turned out fine... yea and why would you be worried about being under your car on stands??? I spend a lotta time there and as long as you know how to use a jackstand there is really no need to worry!

the damn BMR instructions tell you to put load on the suspension....so why does everyone have to argue and say something about it....if you want to follow the directions and do it how the manufacturer tells you to do it, then do it that way. if you dont care then why argue.

You gonna cry dude *SNIFF* *SNIFF*

Why don't you re-read BMR's Instructions again. It says, IF USING A LIFT DISREGARD THIS STEP

yeah...you nailed it man, im gonna cry....

" Jack up the rearend until the lower control arms are close to parallel with the ground and leave the rearend supported with the jack.. DO NOT SUPPORT BY REAREND ONLY! If using a lift, disregard this step and move on to step 2. "

no ****, you cant jack up the rearend if you are on a lift...

why not use what you want... I mean give me a break, its your car.

Take everyones advise and take what you want from it.

Personally mine will be welded using a pit, so no lift at all, not nessisarly becuase I think its better, but its what the guy has.
I really like it that way, seems the best bet for getting it how they should.

on a side note, I know a stang that had a lift do it that uses the 4 points on the chasis, and after they were welded the car had new creaks, and didnt sit right, after a short time you could see the welds stressing. he had them cut off (not easy) and welded with a pit.

I'm having my BMR weld-in Sub frames put on using a lift with full load on the suspension.
I'm only doing it this way out of personal preference. Just do what you guys want. Everyone is different.

So what you are saying is that it doesn't matter how the chassis is loaded, because it doesn't deflect?

If that's the case then why are you installing SFC's?

Yes, I'm being rhetorical If the SFC's are not installed with the suspension loaded than you are preloading the chassis.

Will the car drive? YES. Will it fall apart? NO. Is it ideal? Certainly not.

You can do things any way *you* want but some of us here are trying to promote proper methods. If half *** modifications is good enough, use duct tape for all I care.

L.O.L @ duct tape! good one..... Auto part stores & probably K-mart, Target. etc. sell those drive on polyurathan ramps for $20 for two so for $40 bucks you can get all four tires supported..... Bill...

p.s oh, not that you guys on the un-supported side of the fence care but I was a welder for 12 years and it would be far superior to have the suspension loaded when welding on the sub-frame connectors.......but like we used to say about sub-quality work when out on jobs "Looks good to me, besides you can't see it from my house"......

i had my KB DD sfc's installed last year. i believe the instructions say to have the suspension loaded before installation.

my local muffler shop charged me $15

i bolted them up and drove the shop (40 miles) with no problems.

it took an hour or so to weld them in.

they are very easy to install, they have very detailed instructions, the guy at the muffler shop had never did a set before. i showed him where to weld and he welded

Nice slip!

Can't dispute any of what I said, eh?

I'm not giving YOU advice, I have a hunch you're too good to take advice from anyone. People that read these boards just might be appreciative of advice and reasons why it's given though "patna"

No Im just saying dude.. Your just trippin.. Don't need to nit pick at EVERY SINGLE little thing like that.. Im just saying that OK the MOST BEST WAY of doing it would be to load the suspension.. But it's SERIOUSLY NOT going to matter if you have to use a lift and can't load the suspension dude... Seriously it's NOT going to matter... If the chassis in your car will tweak THAT MUCH beacuse of it then your car has issues That's all Im saying dude... Your advice is good but you just don't need to trip on the tinyiest of $hit when it's not that big a deal
