I'm looking into having Alston and Spohn SFCs at the same time. I *think* I have an idea of where/how the Alston SFCs install, but I'm not positive. Does anyone have a picture? Or does anyone happen to have a picture of the Alston AND Spohn installed? Or, can someone like photoshop or MS paint where the Alstons go on this picture I found? Thanks.

 

I haven't done it but i asked the same question a while back. As i understand it the alstons connect the subframes. they go from the fraim rails/subframes that are outboard of the tranny to the frame rails that come off the back of the car. They are not supposed to interfear from what i hear but i believe that info is based on the tubular spohns, that picture is of the older box spohns. I think if you search on it you will find what you are looking for

 

Terry Hartman had (has?) this setup on is car. He had pictures on his website but the site appears to be down.

Digging up the past here, but I have a feeling you know the answer to this question.

Is it possible to run a BMR Trak Pak with the Alston SFCs?

 

Where'd you get that pic? Looks like there are SFC's already in that one. Anyways, I just installed the Alston's on mine, and it is VERY obvious where they go once you get under the car. The ends that go on the front subframe are "cupped," while the back ends are boxed, so it's pretty easy to see once you get ahold of them. Don't know if you're still interested in doing it (its been two months since you posted), but thought I'd help anyways. Here's what it looked like with my black powdercoated ones!

 

I honestly don't know. But, one day I will have the answer since I plan to run their Xtreme Duty Torque Arm which mounts up like the Track Pak.

That pic's been posted 100 times on the site. Yep, those are Spohn's old boxed SFCs installed on the car, and it really lets you know where they attach.

here ya go

 

last one

 

Yes it is, I have the trak pak on my car with alston subframe connectors. I had my trak pak bar welded to the subframe connectors. PM me later on if you need photos.

 

how is the Mopar 8 3/4 end end working out

 

SLP_GTA the rear end is good, none of the weld have broken, we didnt expect them to ,its good, i love 4.10s and the 60ft times are awesome , all i need now is a real engine and a beefed up tranny and ill be all set .

 

Man, those Alston subframes look really good. I'm going to be doing the Alston/Spohn subframe conenctor combo. nolanr0413, where did you go to get your subframes installed? A local muffler shop or a chassis shop? I'm in NYC, can't find a place that's ever done subframe installaction before.

 

I installed my own, but if you can't do that, your average muffler shop can do it. If you can't tell from the pictures, its CRAZY obvious how these things fit on there, they're basically cupped or boxed on each end and it's painfully obvious what goes where, so anywhere that can weld can get it done.

Once you receive them, take a good look under the car and compare with the pics given to figure out what to tell the shop - they should be able to see it on their own easily.

 

SpectreGTA91 unfortunatley those sfcs are not on my car , they are a picture of , i think, one of the moderators cars. I wanted pics of them so i could show my dad , since he will weld them . I was gonna get them but i might wanna get a t56 and with the t56 and alstons their needs to be some fabricationg, and ive heard that the truss style is better. Im gonna have my dad do it , and im gonna get kenny brown sfc.s

 

Cool, yeah, I'm going to be getting the bolt in Alstons and installing them myself, then driving down to a local shop to get them welded in. jamesbob02, did you install the bolt-in subframes? How was the install? Was the drilling any bad?

 

Does anyone have pics yet of Spohn and Alstons SFC's installed together? Or any comments regarding how the car felt in comparison to just having the one set of SFC's?

 

Spectre,

Sorry, somehow I didn't know there was a reply to the topic, but I'll answer now

I bought bolt in ones, but didn't realize you actually had to drill holes for it. So instead I just welded them in myself. The key is to get the car sitting up high but on its wheels, so the body isn't twisted or something - it needs to sit as it would on the ground. Having said that, the install was pretty easy, if you have the resources.

I can't remember if it would have been difficult to drill the holes or not, but I bet you could do it; other people do! I suggest you find a friend/relative with a welder and use it instead, though.

We just bought a Lincoln Electric wire-feed welder, and OMG it's amazing! I learned how to weld in five minutes, and now I'm doing it all the time haha. Just thought I'd mention that - it's a GREAT buy.

 

Hey James bob do you know any muffler shops with expirence in welding subframe connectors in? I have some spohns and I am really eager to get them installed along with my LCA brackets.

 

Unfortunately, no. I got some welding work done at a place called Big Red Muffler, or something like that, on 12th st in Moore, and I would have trusted them to do it, but I was able to do it myself.

Honestly, I'd help you do it, but we're in the middle of building a shop next to the house so we can have a better environment to work on cars! A month from now I would say come on over, but I understand wanting to get them in asap haha.

You might want to post your question int the SWMG regional board, so some OK guys can answer.

 

Now that I think about it, I don't think your average muffler shop, including the one I suggested, would have the capability to weld in Spohns. Alstons are much more centrally located, but Spohns go along the outside edge and would be very difficult to weld if the shop used the regular "drive up" type bays.

Also, the Spohns seem a little more complicated to install, so I don't know if I would have expected any shop to put them in correctly. Hopefully you can find the resources to do it yourself. All it takes is a welder, someone to weld, a couple jacks, and some thing to set the tires on, like a bunch of wood or something.

Good luck.

 

Thanks man. Yea I was planning on getting everything together within the next week. I am going to be putting on the 200's and I want to go to the track shooting for 10's. Went 11.78 with the 100's and Im not going to do that with my wore out frame. I guess I will search the Cofba boards and see where the 4th gen guys go

 

Man that's SICK what you're accomplishing with LT1 intake, L98 heads, and a 305cam! Definitely something to think about for a future combo.

 

its not too bad. It really likes the N20. Well f i get everything done we will see if those Ultra light slugs like the 200 pills
If not then it will give me more incentive for my next project 406 thats a settup you should look into. couple guys on the DIY Prom board are going lowwwwwww 11's with 123-125 mph's sorry for going off topic

 

Has anyone tried adding another bar between the rear subframe to where the spohn's attach in the rear? seams like it would help connect the 2 subframes better.

 

Could someone post a pic of the BMR trak pack? I need to eliminate my stock torque arm mounting points because I now have a vette trans which has no provision for a torque arm. The BMR trak pack seems to be the solution.

 

TTT:- Does anyone have pics yet of Spohn and Alstons SFC's installed together? Or any comments regarding how the car felt in comparison to just having the one set of SFC's?

 

what he said...

 

Holy old post!

I installed both the Spohn and Alston SFC's at the same time, so I can't comment as to how different it feels with one set versus two. However, I can tell you that the chassis rigidity feltr markedly and undeniably improved when I installed them.

They are added weight, but I feel the increase in stiffness is worth it. Also, the added mass in down low and if anything will move the centre of gravity lower.

If you require a pic at a specific angle/section it's not a problem. The main thing to remember is that the stock and any 'over the counter' aftermarket exhausts may/will not work. You have to be ready to go for a custom exhaust when you go this route.

Good luck with things.

 

"That's right, Robin," and the timing couldn't have been better.

This is exactly what I was talking about doing in the Convertible forum this week. The ASC-installed outboard-mounted rocker SFCs are completely visible on non-gfx 'verts, and it's ugly. So I was thinking I could mount some Alstons first, then hoping I could remove the ASC pieces, and then add inboard-mounted rocker SFCs like Spohn's.

I would think the Spohn's should work even better than the ASC pieces... and it sure would look A LOT better.
