Don't get bolt-in ones; or if you do, get them welded. Bolting them doesn't work. The stress and movement on them will elongate the bolt holes, and then your car will still shake and shimmy, and you'll just have even more loose parts banging against each other.

I plan on a set of bolt in Alston SFC's. The can be bolted in, and then welded later. I havent heard a bad thing about these and the work with dual or single cat cars.

The Comp bolt ons were easy to put on and required no mods to the floor. If you have the right tools it takes about an hour to put them on. As for the bolts comming loose, my buddy has had the bolt on SFC's on his car for about ten years and there tight as ever. It'a all a matter of preference. I will say that any stock exhaust will have to modified to accomidate the SFC's made by comp. eng. as they cross over right before the cat location. My friend that has run them for years on a T Top car has NO complaints and they tightened up his ride considerably.

I have the Comp. Eng.sfcs on my 84Z-28. They are the bolt on type. I havent seen a set as beefyas these are. They truly connect the front to the rear in the most important spots. They go from the lower control arm, up the sill, and over to the center frame. I changed the tubular bit that runs from the sills to the center frame to a flat steel plate with holes in it to bolt to the pan if needed. I did not need it because the connectors are great without bolting to the pan. I had to change the exhaust a little but my exhaust is not original. I couldnt see it being much of a hassle to install with standard exhaust. Any shop could easily deal with the situation. Very happy with the bolt-on types.

I'm running spohns oldstyle (boxed) sfcs. I was really impressed with the product and you can't beat having steve himself write answers to your emails and send you the tracking email with the number. Only bad thing about them was the wait. I had to wait about 4 or 5 weeks before they were sent out, but it was all worth it. I wouldn't get bolt in kind unless you weld them in too, like stated earlier. Over time the bolt holes will elongate and become kind of slotted leaving the sfcs loose and rattling, which means they'll no longer hold the car together like they should. I love my spohns especially the side weld ons so it connects the transmission tunnel to the sfcs too.

SFC's are like the STB's with PRO & CON on MFG and TYPE. So I say go with the one you like and suits your application & wallet. Or else this Post will go on and on and on and on........Also I have the Spohn Tube type SFC's & Hotchkis STB.
