I spent most of last evening getting everything installed. And boy what a difference the 4 piston calipers make. The difference is much more than I expected. I can't see the Supra 4 piston calipers being much better than these. The LS400 swap is a much more affordable choice for upgrading your brakes.

There are a few issues that needed resolving. Such as shorter caliper bolts. The SC300/400 caliper bolts are longer than the LS400 caliper bolts. One can either get shorter bolts, use a few washers, or grind the SC bolts down. I chose to grind my bolts down. It was about 10:00 PM when I realized that the bolts were too long. And since no place was open at that time I only had one choice. And it worked out just fine. Also the dust cover needs to be modified to fit over the larger rotors. It can be removed but I decided to just do a little bending to take care of it. There were a few places that were very tight on the caliper mount. I had to remove a small amount of material off of the caliper in order for it to fit, nothing major by an means. The SC brake line doesn't mount onto the LS caliper like it should. It seems the LS400 brake line is a bit different. But it works fine. Has anyone replaced their factory lines with LS400 lines?

All in all the LS upgrade is worth every penny. I think I have a total of $325 invested in the calipers, rotors, "LEXUS" decals, and new pads. Definitely the cheapest big brake upgrade I have ever done. If anyone is on the fence about doing it, do yourself a favor and get off the fence.

i gotta agree they are awesome.
i had 2 ls400 bolts and 2 sc bolts, so i just put the longer bolts on t he bottom where it cleared anything else...

also, the brake line doesn't fit like you mentioned, but it works...i'm not TOO worried about it, but i did get the cut off end of the line...o well

i plan to uprade lines, but for the moment i gotta figure out why i just threw an ABS light(again, it turned itself off for a while...). I'm guessing something with the abs is wrong, feels like it's using the rears too much all of a sudden

What is all I need to buy in order to do this upgrade? Just the Calipers and Rotors off an LS400?? Isn't the stock Toyota Brake Pads just as effective or should I get aftermarket? Do I need to buy brake lines or any of that? Also just wondering with these brakes, are you able to apply full pressure on your brakes (basically just MASH it down) and you'll just stop on a dime?

Best bet is to contact Aliga here on the forum and get the calipers from him. They will have used pads on them with all of the shims and pins. You can get used rotors as well. I purchased new rotors and pads off of Ebay. Try to get the caliper bolts too. Or just use washers or grind the SC bolts down. And you will need Wheels that will clear big brakes. The factory SC wheels will not clear the LS brakes or Supra brakes. I have Supra TT wheels. And a decent tool set.

I haven't hit the brakes real hard yet. Since I bought new rotors I want to break them in befoe I do any quick stops. But from the 50 or so miles I have put on the car since I installed them I can really tell the difference. And they look great as well.

I have aftermarket wheels, not sure what they are called off the top of my head, but what do I check to confirm if it will indeed clear or not?

hey BiZ, who did you get your rotors and pads from on ebay?? i bought some off of there for my ls400 upgrade too but they got the order wrong, they were supposed to send me 2x front slotted rotors and 4x axxis ultimate pads but they instead sent 2x front slotted rotors and 2x rear slotted rotors (both an LS) if they dont respond soon imma put em up for sale in the classifieds (ls rear rotors)

edit:
Sweetser: you measure from the surface of the rotor to the inside of the spoke of your rim, people that have done it before say that you need 2.75' in to clear it but some one pulled it off with 2.5' in and im about 1mm short of 2.75 so i shoudlnt have a problem

BiZ: what exactly did you mean about the brake line not fitting as well as it should? also, where in florida are you? im in jacksonville.

Both brake lines have a tab that puts the brake line in a certain position on the caliper. The ls400 has a longer tab than the sc400, so when you try to install the sc line on the ls caliper you cannot put the tab where it should go. But it does not seem to affect the operation of the brakes. So far I am more than happy with the results.

I am in the St.Petersburg/Clearwater area

Anyone know if this setup will clear the HP Evo wheels, because I have heard that these wheels dont fit a big brake upgrade, but I wasnt sure if this setup might work

did you change your master cylinder too to push 4 more pistons

No, just flushed and filled the system with fresh fluid. It seems to do the juob without a hitch.
