I am searching my local area, (Nova Scotia, Canada) for dealers who carry sub frame connectors. They all sell Comp Engineering.. which upon 1st look, don't impress me. Has anyone used these? They have 3 models,

-weld-in (says requires floorboard mod, i don't like the sounds of that, we have big enough bumps on the pass floor),

-Bolt on (which i would bolt and weld), fits car without mod

-Bolt On but are a bit beefier and won't work with stock exhaust (mentions somthing about cat converter, if that is all i have to lose well so be it.)

I really like spohn, but the shipping would be 1/2 price of the connectors, to get it to my door, + border issues

 

I am in Australia and on my last visit to the US, I bought Comp. Eng. bolt on sfcs. I brought them back and have only bolted them on 18 months ago. I did change the part that goes from the sills to the center member but that would not be necessary. They are fantastic and like you said they are very beefy and do a tremendous job. They can be welded on but that really isnt necessary. My opinion is that they are well worth the money and time spent to install. Remember to have the suspension loaded on installation. Go for it.

 

I have the bolt on Comp. Eng. Sfcs. I had to modify the passenger side unit to clear an Edelbrock exhuast but I'm happy with the results. Welding them in would produce even better results. For the price and ease of installation they are worthwhile.

 

I also have the bolt ons. Had to modify the passenger angle slot in the sub frame connector on the passenger side and make it longer in length to clear frame. Otherwise nice fit....

we used a set of the bolt on style on a buddies car, we also welded them, he was very impressed at how good they worked. i never road in the car before the install to feel the difference.

very easy install too...

 

got any pics of their design?

 

this is taken from comp engineering's website, this is 1 of the 3 types they sell, they claim these ones are bolt on but require car mods .. doesn't sound good to me..

I think i have decided to cheap out.. I have a friend who has built subframe connectors in the past.. I have a welder, torch and sawz-all.. Think i'm gonna buy some tubing and have at Mind you , if i could get a decent pair without being murdered by the shipping I would have oped to that.. Who knows, I could $%^& it up yet !

 

I have that exact set of connectors and the only fab work that would be necessary is maybe the exhaust . I find them great.

 

There is NO bolt-on subframe connector that will EVER work as effectively as a weld-on set-up. That is a fact. As far as the brand goes, IMO, the SouthSide Machine Works Subframe Kit , although it is VERY expensive ($450.00 last time I checked), it almost transforms your rear end into a four-link set-up. Go to Jeg or Summitt's websight, and pull up a picture. If you want to keep the car from twisting and plant the rear end, this is the kit you need to install. You'll be amazed.

 

What would you have against the bolt on sfcs from Comp. Eng.? They are fantastic connectors and have the best of both worlds in that they can be welded in. They are extremely gutsy and fit in exactly the right spots.

 

The fact that they are bolted on.

 

you can weld in bolt on sfc's. That's what the alstons are.

 

I had my BMR bolt-in's welded, they're fine.

 

What I said was Bolt-ons are not nearly as good as ones that are welded on. Bolt on's are great...........if they're welded.

 

im from good old nova scotia too.i wanted the spohn sfc but shipping stoped me too. so i bought some round tubbing and copied them. welded them fast ,total cost me under $100
