Some cars like s10s have them in front on the lower control are and in the rear over the axle to prevent the control arms and axle from hitting the frame on big bumps. The s.Tech should include instructions on how much to cut out of it. By cutting it you are allowing the the car to sit lower without sitting on the bump stop. if the car is sitting on the bumpstop it will limit the amount of suspension travel and cause it to have a rough ride.

The inner fender liner is the plastic piece in teh front wheel well that prevents rain and debris from entering the engine bay. I would not worry about removing these or cutting these unless it becomes necessary. You may end up with a slight rub on big bumps or hard turns at speed and maybe at slow speed at a full turn. This rubbing maybe so sparatic and so minimal you may not need to do anything. Or you may have no rubbing at all. Or in some cases it may rub all the time. then just cut out area rubbing or remove entirely. All cars even the same models are different and all springs even same models can have slight differences so you never know until you do it.

Ok....ok, starting to get this. So the Tein Springs, and then I could also look into struts and shocks. But the teins have a 2.2 drop on front and rear. And the spring rate...3/168 on the front and 3.5/196 on the rear, what does this mean?

1sweetxd answered part of this.

But as far as the spring rate the number before / is metric and after / is standard (american for lack of terms)

what you will be worried about it the standard side in this case the 168 and 196.

What this means is this is how many pounds of force it takes to compress the spring one inch. So the front springs take 168 lbs. to compress 1 inch and the rears take 196 lbs. to compress one inch.

As for you just going to buy springs off the shelf you won't have to worry to much about spring rates. most companies will be relatively the same. that becomes key when trying to do some fine tuning for specific applications and gettign custom springs.
