I just bought a pair of used SLP 3pt bolt in's but they didn't come with any hardware, and I don't want to pay $60+shipping for SLP's hardware kit if it isn't necessary. I am going to call UMI and see if their "bolt pattern" is the same, but if you have any other suggestions that would be great!

The smallest washers go towards the bolt head, with the largest towards the SFC mounting plates (makes a reverse pyramid in relation to the ground). I think I used three washers for each pyramid stack (SLP kit only comes with one weak washer for each bolt, and if you try to really torque down hard on this, the washer will distort and partially collapse into the mounting hole - the stack of three progressively larger washers allows a great deal more torque). I got everything necessary at the local hardware store, although I did use the mounting bars that came with the SFCs from SLP. I suppose you could make your own mounts with some thick, cut steel bar that's been drilled and threaded.

One more question for you so I don't have to start another thread. I have read on here that when installing SFC's that you want the suspension loaded, but in the SLP instructions it doesn't mention anything about that. Any recommendations on how to install them with just jackstands?
Sorry for the thread jack, hopefully this helps out some others too.

I have installed these on a few different cars. I have sometimes used ramps, or a jack to lift the car for positioning/initial hand-tight mounting of the SFCs. But for actual torquing of the bolts I have always made sure that the suspension was fully loaded with no portion of the body on jacks. Not sure how important that is, but I always felt it was a good idea for everything to be loaded for final torquing as it would be during normal operation.

-weld in is no maintance, quieter and generally whats the chances that you will take off the sfc when u sell the car ? parting them out is a null point
-tubular v boxed boxed are heavier and unless thicker guage like is available a =thickness tubular will be stronger
-black v red is personal i went black figuring scratches will be easier to respray paint

I went 2pt tubular J&M weld in. they were just 100$ and the best deal with high quality ends.

bonus tip the sfc extend the jacking point area so a jack and stand can fit easier
