Well the 97z28 has weld ins.... But i had to pay to have them installed. My dads looking at Bolt Ons is there any diffrence.. Hes not making it a race car or nething so hed just want the car little stiffer.. would Bolt ons be better or would the weld ons be better? I kno the boltons wouldnt cost nothing to install.

 

I asked that question about a week ago and the answers I got were weld would probably be best. The reason; with the bolt-ons the bolts may back out or actually stretch the whole or shear the bolt off overtime. If i understood right.

I'm in the process of looking for some slp's.

 

Yes, weld. The bolts can come undone. But they will over time elongate the holes and become less effective. If you're strapped for cash you can always bolt them in and weld later. I think the bolt in are a PITA because you have to remove your carpet if I'm not mistaken.

 

you have to removie the carpet for the weld ins?? that I dont want to do... I guess weld ins are the best. I love em on my car.

 

no you dont need to remove the carpet when welding the SFCs in. the only thing to be careful of is the fuel line on the drivers side.

 

Weld ins are stiffer. Everything Terran2K said and with one input..don't forget to paint over the welds afterwards unless your SFC are rust color and you want them to match.

 

I was saying that I think you have to remove the carpet for bolt in's. Not weld in's.

 

My SLP weld ins just arrived today and a buddy of mine said he'd charge $80 to weld them in, and while I'm at it I'm also going to install my BMR CM round LCAs, SLP boxed phb, Granatelli Tunnel brace and ST 35mm front/25mm rear sway bars. I can't wait to drive the car and feel the difference.

 

Sounds pretty exciting. I'm getting ready to do some serious suspension upgrades. Let us know how your car handles.

 

Like i said the z28 has them they are awesome, now my dad wants them too and hes not sure if he should go bolt on since they wouldnt need to be welded in by a shop we could do it ourselfs, But weld ins seem to be the way to go... But how do u install bolt ons is there really any diffrence between the two? thats what i want to kno.

 

Yes there is a difference in the strength of the mounting of the SFCs, because it would take a whole lot more stress to break a weld than it would to break a bolt.
That's the biggest difference if you're not auto-xing or road racing or drag racing every week and all you do is cruise around in your car then bolt ins should be fine. However as others who have used bolt ins ( I personally never have ) have stated the bolts can come loose where a weld won't.

 

I was looking at getting a pair of bolt-in SFCs. Do you really have to remove the carpet? I thought I had read that you have to do that with the weld-in to avoid burning the carpet? Mayb that was a bad rumor. Also... what is the best bolt-in SFC to buy... BMR? Hotchkis? SLP?

 

No, you don't have to remove the carpet with bolt-ins. Some people remove the carpet for WELD ins though, to keep from burning it.


I've been running bolt-in double diamond SFC's for 2 years. Other people in the club run the same SFC's and have had them even longer. None of us have noticed elongated holes, sheared bolts, bolts backing out, etc. ... even with 1/4 mile and Auto-x use.

In short, there is nothing wrong with bolt-in SFCs. Whenever I'm under the car for any reason, I usually stick the wrench on the bolts just to make sure they haven't backed off. Never been able to turn it.

 

Does anyone have a brand preference? Also... about how many hours should I set aside for the install?
