I need some suggestions for a good set of sub-frame connectors...

any input, suggestions, advice, experiences are welcome...

 

I'm ordering Alston SFCs from TDS on Thursday, for my 'bird.

 

as long as they connect the 2 sets of frame rails, you are gtg. i personally like the setups that the lca's end up bolting through

 

-weld in
-bolt in

is one better than the other?

 

Bolt-ins will wiggle over time & wobble out the holes, making them loose & less effective.

The Alstons I want are bolt-ins, but my intention was for using the bolts for ease of installing them, then welding them in afterwards.

 

I bought UMI subframe connectors, they are VERY good quality, are very affordable, the lower control arm bolts through them,, are tucked up nicely, and the fit well with stock exhaust (single cat, not sure about dual...)

 

Check Spohns web site, nice weld in SFCs.

 

"Nice" is a matter of opinion.

I had some. Cost $244 new & sold them for $150. IMHO, bad cantilever design & parts would not have fit together without cutting & being modified.

I use UMI. Buy them through summit to save on shipping. One of the best mod's I have ever done to the car!

 

Also use UMI. Damned good quality.

I used South Side Machine subframe connectors. They are made of thick wall square tubing and weld in along the entire pinch weld, fitting tightly into the body at each end and becoming part of the chassis. The LCAs connect to them at the rear. they dont have the K-bars that run to the rear crossmember like the UMIs do. That's the one thing I would improve.
