gen 2 brake upgrade
so my calipers are arriving today, i will be fitting them on, i need to know if i am going to have any issues like the backing plate getting in the way or the lower ball joints not letting the caliper bolt up so i can turn my wheels to make sure i have the correct clearance...any input would be appreciated, thanks

you should be able to just MOUNT the calipers without the 2nd gen LBJs but you won't be able to drive the car like that at all. but for fitting purposes should be fine. backing plate MIGHT need to be cut/replaced with 2LS piece.
just to confirm, you ARE using 2nd gen rotors as well RIGHT, the brakes won't even come close to working right with the 1st gen rotors.

There was a brake job done on the car about 10k miles ago by Lexus (previous owner, I have the invoice), they totally screwed it up. Not only didn't it stop well, there were all kinds of vibrations. All's well now...

The right rear rotor was warped and the left front was oversized in thickness. There wasn't enough room on the outboard side of the rotor for the pad to fit between the rotor and the caliper. Because of this, the outside pad had worn down considerably over 10k miles. The outside pad material was noticeably thinner than the inside pad. When Lexus installed them new, they must have had to use a 3lb sledge hammer to get the caliper over the rotor and pads. The replacement rotor was fine.
Before all this, I picked up an infrared heat sensor at the local Autozone and shot the rotors after running the car for around 20 miles on the highway. Found that the right rear rotor was running almost 30 degrees hotter than the left rear. Left rear was 98.5 degrees and right rear was 126/128 degrees. Found a similar difference between the left and right front. Normal operating temperature for a front rotor is somewhere in the range of 135 to 150 degrees. I'm sure ambient temperature would effect this result somewhat. It was around 55 degrees out when I got a reading of 142.5 degrees on the fronts.
Figuring out all the vibrations on this car has been a real challenge. I'll post a summary of everything I've done and discovered one day soon after I work out one or two small remaining bugs. I've learned a lot and my wallet's a lot thinner.

has anyone fitted the rear that you know of? i saw in the write up it was a consideration but was not confirmed to work.
*edit - did a couple more informed searches and found plenty of info. still haven't found confirmation on the rear though.
