Subframe connectors. Bolt or weld?
Which way should I go? What are the plus and negitives to each? I like the Idea of bolt in's, so I will probably go that way unless I am convinced otherwise. Also will I see any drop in E.T. with a mostly stock car? Thanks

A piece that is designed to add rigitity to your car must be welded in to do that best as possible. A flange that is retained with just a bolt can still flex from the point of the bolt retaining it.
Other hand a flange which circumference is welded to the car wont be near as apt to flex as the bolt on piece would be.
Not to mention there is alot more joining the pieces to the car when welded in, dependant upon the design of SFC you go with.
My $.02

We sell alot of the bolt on styles, many people tend to purchase the bolt on set-up for ease of installation. This allows them to install the item themselves and have a garage at a later date weld them in place for them. We usually recommend to weld them but we have also had great luck with our bolt in designs.

how many of of you bolt-in guys have 60'd uner 1.70?
i know that mid 1.6 60s twisted the **** out of my car before adding the sub-frames...so bad that i honestly think it made my driver's side window leak (t-top car..)
straightenedthe car back up, welded in some sub-frames, and now many 1.6x 60s later, i still have no leaks or squeaks.
welding ftw. ever hear the phrase: "if you're going to do something, do it right."? it's a good philosphy to exercise when it comes to PERFORMANCE upgrades, as a chain of events usually occurs when ONE part lets go.

I just got bolt ins and they are in the mail. I just had someone tell me that they are 90% sure that they will not bolt up to my car, he said that the holes in the front are probably screwed up from jacking the car up with a jack with too small of a foot print ( which I have done ) Thats just great. They are 3 points, so would it be a bad idea to just bolt up the back two points, then drive like 15 mins to a welder? and then just have him weld the fronts up.

Weld them.
I have helped install two sets of bolt in SFC's (slp brand). With both cars, after a few months the bolts had loosened up a bit. We tried loctite and tightened the bejesus out of them. Didn't matter, they still had give some time later.
