You'll need calipers, rotors, hardware/shim kit and a new set of pads. Your old set are a completely different design that won't work with the LS calipers. You'll need to source a set of LS caliper bolts as well. You could also grind down the bottom of one of the SC bolts to clear the rotor the top one will clear just fine; using a 3mm lock washer will accomplish the same thing. Some people have said they needed to grind part of the caliper to clear part of the mounting point, I didn't have to on mine.

if it's pulling during braking, I would suggest examining the suspension components (front and rear). bad bushings, shot ball joints can cause a pull.

Driver's side bushing is shot (UCA or LCA, either one of them), trust me.

man it sounds like you have a siezed up caliper. I would check that first, then move on to your suspension components.

i got the same problem. check your control arm bushing, lift it up and take off the wheel. grab the rotor and try moving it side to side, push on one end while pulling the other. i believe its my passanger side bushings that are deteriorated. also get an alignment.

Also check your alignment and how your tires are wearing.

How bad does it pull to the left? and how hard are you braking? because alot of slammed cars ive driven kinda pull to one side under hard braking from my experience.

Well, most common car that pull to one side when braking is caused by seized up caliper.
If your pulling to the left, that means that your front right caliper is probably seized up due to it not being able to move and slide.

Your guide pins are most likely the cause for the caliper seizing up. Check the boots that protects and lubricate the guide pins. If there are any rip in the boot or it looks too damn old, water and salt may have enter and the grease may have dissolved in the mixture.

Other suggestion from CL member are great also. Other suspension problem can cause this symptom as well. We can only inform you the common fix for the common problem.

^ I agree, one thing to mention with the LS400 calipers make sure your wheels will clear them. I believe you have CCW's though, so you should be ok

As mentioned usually a pull to one side will be a faulty caliper seizing up and on its way out. My SC300 is starting to do the same and you can not only hear it make noise its also generating tons of brake dust in comparison to the other wheels. If your one side has major brown dust from brake dust theres your culprit otherwise it may be a bad alignment or worn / destroyed suspension pieces but more then likely the caliper.
