I did quite a bit of searching, but couldnt really find a definitive, one stop, kind of thread for SFC's. Especially for convertibles. For example I already have Alstons, via top down solutions, however I want to run two sets. Now I know Alstons and Spohn can be run together, but what about Alston and UMI or BMR or... or... Anyone know the combinations that will work for Convertibles specifically?

1. Alston and Spohn
2. ?

I asked the same question and only got a few replies and they stated that spohn and alstons play well together but I am hoping that UMIs will fit. I have them on a t-top iroc and love them. Mine flexes so much I cracked my windshield so I will be installing two sets and probably adding some bracing between the two sets.

what is the UMI part#? Are they perimeter style? Compare them to the Spohn's one and if the are the same style then, they should match the TDS Alston's one's, wich are in my opinion, very sturdy and change your ride a lot. When cornering, entering a parking lot, or launch, you definately can notice a change. Spohn's should be as good as your UMI?!? I have Spohn's rear control arms with relocation brackets, panhard bar and steering brace and every parts works fine, install easily and looks good too. The have a Black friday sale going right now!

Since the Alstons are the only inner set of SFCs made that actually attach to the rear subframes.....All of the outer sets of subframes will work since they all really only attach to the LCA mounts & not actually to the rear subframe.

But as to what fits a vert with its factory sheetmetal SFCs? You'll hafta buy some that specifically fit a vert, which most will, I believe. I'm not a vert guy so don't take the fitment I said as gospel, just what I understand about what the makers say about the fitment of theirs.

That was kind of why I was asking is the sales this weekend. I can get the UMI's for less money and save on shipping But may just bite on the Spohn.

Between the 2 brands.....

Spohn is tubular.
UMI is rectabular.

Spohn only connect to 1 side of the LCAs.
UMIs cradle the whole LCA mount.

Spohn cross bar mounts are flat connections to the unibody.
UMI cross bar mounts are L-shaped & provide more mounting surface to the unibody.

Spohn is $179.15
UMI is $203.49

So the question is......Do you prefer tubular vs rectangular & LCA half mount or LCA full mount? Less mounting area or more mounting area? And the $24.34 difference. And then which one is closer/shipping cost is cheaper.

UMI Performance

Hello, Thanks for considering the UMI SFC, we appreciate it!

I think the price you have above for the Spohn SFC's is bare metal? If you check out their site they are charge $45.00 for powder coat where our we build our powder coat cost into the price. Also you are correct on the difference, we build a full control arm mount at the rear.

If you want to save on shipping Summit Racing is offering these connectors right now at 15% off and totally free shipping, they also have them in stock ready to ship-

If I am not mistaken it doesnt say that the UMI will fit a convertible. I know the later convertibles have the sheet metal SFC box down the sills. Am I right or wrong?

Quoted from the UMI site:
This unique design utilizes a 3 piece design, allowing (6) major weld points through out the chassis of the vehicle. Subframe connectors fit hard top, T-Top and convertible models."

Yep.....Spohn adds $45 to get them powdercoated (never realized that) so turn the $24.34 more for the UMIs into $20.66 less for UMI because Spohn charges extra to get an "equal"(powdercoated) SFC product.

UMI Performance

As Blackenbird mentioned, they do fit convertibles.

Thanks Blackenbird

I have umi on my 350 t-top iroc and love them. I use them for jacking the car up since they are strong enough to hold my floor jack in any location. I like that they weld in also and my muffler shop ground off the powder coating and they fit very well. They made a huge difference on my iroc and my vert flexes a lot more so I will probably use two sets on it.

Yeah, but will the UMI work with the Alstons?

BlackenedBird

iTrader: (5)

Why wouldn't they work together? They both attach in totally different places & in no way could interfere with each other.

Your question has as much logic as asking if the color of carpet can interfere with a headlight.

Jstcrzyengh

iTrader: (2)

Its perfect logic if you don't know WHERE they connect and if they are different as I do not have the UMI's in front of me. Also as previously mentioned in this thread different years, apparently, have different structural points that could cause issues. But thanks for reading the whole thread

I have read he whole thread but I am not going to backtrack to reread to try to understand WHY someone makes a statement like yours. Don't physically need either style in front of you to look at to know where they mount when it would have been MUCH easier had you ASKED, or used the Search feature to find pics, where the different styles mount & if they could interfere with each other, rather than making the statement that you did (and Edited).

Not only that, but pics are posted on TGO multiple times showing where both styles mount. A simple Search would show you that.

Jstcrzyengh

iTrader: (2)

Wow March 2011, November 2000 didnt know there was ever a search feature on here. However, did you happen upon that?

and to reiterate, since you said you read the whole thread, here are the first few words that I wrote:

"I did quite a bit of searching"

and NO there was nothing definitive with UMI and Alston's together on a convertible. Spohn and Alston, yes, but again I already said that in the very first post.

BlackenedBird

iTrader: (5)

Not enough searching, since these are pics of double SFCs that I got off TGO before I did my SFCs.

TGO was started around 1996/1997 & there was a 3rd gen Forum before that (that was always broke a lot). You will be hard pressed to ask about anything that hasn't already been answered 1000 times, other than about LS series stuff & any NEW items that have introduced recently.

Now wouldn't of posting those pictures been a LOT easier than the typical attitude post?

Also, again, do a search where as for convertibles people running UMI and Alston's and its a whole different ball game. I know you don't know my background, but trust me when I say I know how to search a Vbulletin forum.

I agree, Mine is a 92 Z vert and has a metal box along the outer edge of the car which I am sure ASC added but I thought all verts had this or at least all ASC cars. I wasn't sure if this box was in the way of umi SFC or not. I did a search also but usually someone has recently done something like this and has seen a new product or learned a new trick not posted yet. I like discussing this stuff and getting other peoples perspective on ideas. Two heads are better than one. I live in Arkansas and we don't see too many new products or new ways of doing things other than hunting or fishing or 4x4 truck stuff.

I might get the UMI's to match my Alston's after all...BTW, the Spohn's were on special for Black friday at 169.99$ bare metal. They usually sells for 199.99$ bare + 45.00$ for powder coating + shipping fees. The UMI seems to be the best bang for the bucks, specially since they ship for free @ summit racing. I will keep my eyes open for Christmas specials...

blakecharles

I read that the JEGSTER's will fit a vert. They are bolt on's tho. That's what I'm starting with, at some point I will weld them on then use the MAC inner SFC's to match.
