My first post- Bolt on or Weld on Subframe connectors?
I been reading this site all day and upto page 22 on the this suspension forum. Anyhow, I am wanting to put some subframe connectors on my 82, but I don't know what the better of the two where. I am going to go with Spohn just because Steve seems like a person that will continue to develope things for our 3rd gens unlike every other company that sells out when a new model comes out. I do not have access to a welder, so bolt on would be nicer, but if their is a big difference in the two I'd rather pay someone to weld them.
Thank you in advance for the responses.

you can bolt them in, then take them somewhere to be welded up.

Weld. There is no comparison. The bolts will wallow over time. Welding them distributes the sub frame forces evenly and not entirely on the bolts themselves.

So in short:
bolt them in, drive to mechanic/fabricator/friend, pay him $/beer, get it welded in. Worth the extra little bit of $ to get it welded in.

I've been debating on which SFCs to buy for a while now too. I'm going to be getting some before next track season. Bolt-ins seem nice and easy to work with and then get them welded in, but I'm very tempted to buy Spohn's weld-in. I wish his could be bolted in though...it'd make things easier to bolt them in and get them welded, even if I have access to a welder (uncle).
