subframe connector

[uwilluz]

besides slp does anyone know where i can get one?

[Killer_bluebird]

SLP's subframes are of the double diamond kind and are offered in bolt-in and weld in. Other Companies that make Subframe Connectors are Kenny Brown (Double diamond, weld ins), Hotchkis (Tubular), Spohn (Tubular), BMR (Tubular and Boxed), Umi Performance (Tubular, Boxed and Double Diamond) and G2 (Tubular).

which one is better? weld in or bolt on?

thanks

[Killer_bluebird]

Bolt in will work but weld in will give you less chance of failure under stress. For a mild street car that is not going to see the track often the bolt ins are ok. But if you start puting the power down, going to the track or road course, or spraying often I would go ahead and get the weld ins.

subframes are overated and unnecessary if you're not tracking.

umi performance 3 point bolt in's is what i have.

I have the BMR boxed, like being able to lift the whole side of the car with them.

subframes are overrated and unnecessary if you're not tracking.

Curious as to why you feel that way?

This past weekend I started my chassis & suspension upgrades in the WS6 T/A. I installed the SLP SFC's, and the SLP tunnel brace with Drive-shaft loop. Also installed Hotchkis STB, LCA's, Panhard bar, new poly torque arm bushing, and a T/A billet rear end cover with preload adjustment. Still have more to go.

Totally new ride! no more creaking and popping from T-Tops, and rear hatch. Much more positive feel and control in turns, pulling out of and entering steep driveways. No more twisting and flexing in hard cornering, car is easier to handle and control. Starting to feel much more like my IROC in handling. It (IROC) has full suspension re-work, except SFC's. But it (IROC) is a hard top car, no T-Tops. Both the T/A & the IROC-Z are A4 cars.

I personally like the stability of the DD (3 point SFC's) My SLP SFC's were purchased used for $100. I stripped and refinished them and am happy with the result. Undercoated all attach and contact points after install.

My $.02

Have pics if interested.

Anyone how owns a f-body should know that subframe connectors are damn near a must have and should be one of the first mods.
I'd say any brand is good enough.

The tube or square channel Which should i get. Do the square channel hang lower.?

The SLP Square Tube DD do hang down a little lower than say the UMI DD's, on the outside bars. The outer tubes of UMI tuck up into the body channel better. So do SLP's but the larger box construction hangs a little lower. Had the car up on two different drive on lifts without any contact problems. The second was a Front End Alignment lift with fairly steep ramps, no contact!

From looking at UMI's SFC's it seams that the center bars hang lower than my SLP's.

The UMI's are prettier, but my car is a daily driver and I'm more concerned with function than looks under there. Plus I plan on undercoating the rest of the under-body. Corrosion protection and sound deadening.

Here are some Pics from UMI's Website on Under-body shots of SFC's

I will add some side shots of my SLP's when I get them. For now here is a shot of the underside with SLP's. (Note: The black over-spray is Undercoating at attach points and where the SFC's touch the body)





Simply from a cost perspective I would go with the UMI's over the SLP's. UMI's are cheaper. I got my SLP's used for around $100. No contest.

Here are the side shots:

Have other under Body shots of LCA's, Tunnel Brace, SFC attach points, Panhard Bar. . ., and under hood with Hothkis STB if interested. Let me know, will post.

Thay seem to hang fine thanks.

[caseyWS6]

ah man, I know I need them, but I didn't know you would actually be able to see them, (probably a girl thing) which ones are best for a vert? I've been hearing kenny brown or slp, is there any on the market that are less visible? I can't go to the track anymore without a roll bar anyways, but it would be nice for the mustangs at the red lights. lol

I went with Aadco boxed weld in. I got them brand new for $80. Gotta love working at Year One.
