Like I said, seems like it makes sense that bolt-in's would be better than none at all, but some of you with more experience with f-body chassis may think otherwise - what's your argument?

Reason I ask is because I don't know how to weld but I want to learn how AND I'm concerned about doing what I can to preserve my 77k mile chassis right now. I'd rather learn how to weld (for other reasons aside from just sub-frames) and then do the work on my car on my own. It's posible to weld up bolt-ins isn't it???

Also, maybe you all can help with this - there is a guy on ebay that sells sub-frames for f-bodies - user name is dshop2000 - anyone used his products? The plan was to buy a set of his bolt-ins to hold me over until I can reinforce them by welding them in.

What do you think on this?
Thanks, K

 

yes, bolt-in SFCs are better than none. I've had them on my 4th Gen SS for 4 yrs now. They'll get welded in after the ext'd warranty expires.

My 3rd Gen T/A has them welded, since it's my track car and I had the manufacturer (Spohn) weld them in when I went and picked them up. Never heard of the ones you mentioned.

Just be sure that you have the suspension 'loaded' when you put them in, welded or bolted.

 

hey what u mean by suspension loaded?well about the first guys ? and ask it a while back turns out weld on arebetter but bolt ons will do fine to but u cloud buy weld in ones and go to a muffler shop and let them weld it on for like 30 dollars okay am installing sphons sfc and another company the weld on a diffrent area so im gonna have 2 sets under my car for ultimate strenght

 

yeah weld ons are better because after a while the holes can elongate!! but buy the bolt ons if you must then weld them later!!

 

... it means don't put the car on a lift that allows the suspension to hang down (unsprung). Use a drive on ramp style that lifts the whole car, suspension 'loaded' as it sits on the ground.

 

So you're saying I can get SFC's and have them installed for $30?! Or are you saying install bolt in's and then get them welded for $30?

I'd like to get bolt ins then later welded on. How much would it cost to have them welded?

welding is a service provided locally, so it would depend on where you went to have the work done.

you install the bolt in SFC's then find a shop to weld them in.

 

Does anyone have just a rough idea of how much it would cost?

 

I got quoted anywhere from $90 to $200+. I still haven't gotten them installed.

 

i got bolt in sfc. bolted them in myself then brought the car down to a local garage. they welded them for free....so i bought them lunch for being nice.

 

Most places charge $50 just to turn the welder on, then so much per hour.
