I would get the bolt-on SFC, for the sole purpose that if you ever sell your car, you could take them off and sell them for $200+

Little over 4 years with SLP SFC's bolted in. Nothing has come loose or moved. Would prefer welding them in, however I work on my car in a driveway on jack stands and like the idea of being able to unbolt them if necessary.

I'm not sure that its really gonna matter one way or the other. Mine are welded in. and after having my trans and my engine out it would have been nice to take 'em out for exhaust reasons. My exhaust is also all custom and welded in which might also be part of the problem. but either way... I have never heard of any real problems either way.

Well since the convertible ones that UMI has out are bolt in style only at the moment guess I'll have to bolt in the driveway and then weld them once I find a shop. Shouldn't be an issue apparently.

Default Save money my way if u want $$$

I bought SLP weld in ones. Then I made the plates where they bolt in. I don't wanna weld them cause if I ever need to remove them it's a bitch!!!! I painted them red and they are awesome. Firmed the ride right up! HUGE difference! Slp weld in sfc's are identical besides the bolt ins are $150 more with the hardware. Here's my pics.

Exactly what I am doing....again. This time I bought the UMI bolt-ins, and will weld them in eventually. I had the SLPs on the car I just laid to rest. And even bolted in they made a HUGE difference in how the car felt & performed. I ran 1.46 60's with no sheet metal damage. And I ran the car on a road course & in a road race with no mishaps.

As for improving your ET, yes. They reduce energy wasted in your car's frame twisting, & hence more of your HP & TQ gets transmitted to the tires. So the more power you make the more your car will benefit. I can tell you that once you progress past mid 12s, they are the difference between straight & wrinkled rear fenders if you race a lot.

What all they do for cornering I am no expert about, but they made my car feel like a go-cart. So I know they help, just not sure exactly how.....

2 things to consider. If they are standard 2 point connectors I would weld them in. They should never get in your way. If the are 3 point connectors such as UMI or SLP bolt em in! They are tuff as hell!
