Looks great, congrats man.
I was planning on doing the Supra upgrade soon, so it's nice to have another option. One thing I was wondering for a long time is what you mentioned about the ABS logic not compensating for the additional braking power.
Is the computer controlling the anti-lock a learning computer? Will it adjust to the bigger brakes over time, or does a big brake upgrade render your ABS pretty much useless?

any brake professionals want to chime in here? this is the only info i'm waiting for to make me purchase these brakes....hey dennis,how was the abs operating before the upgrade? and does this only happen in the rain? did you change the brake fluid? master cylinder in good condition? any warning lights on the dash?(abs, trac). stainless steel lines installed?

Can someone with this setup please compare the calipers and see how much further the LS calipers stick out. I'm sure a bunch of us with aftermarket wheels would like to know if our wheels would clear. Thanks.

You need about 2.75" from the rotor to clear the calipers. (info provided to me from Aliga). I just bought the other set he had available. Hopefully I'll be able to complete this sometime next week.

I am not familiar with the specifics that Lexus might use, but in general, anti-lock brakes work in a simple manner, all centrally-controlled way before the calipers, so using different calipers won't affect it. Rather than type it all out, here's a primer:

Hey Dennis,
great work man....reminds me of when I put my TT brakes on 2 months ago......bigger brakes are a must for our cars.
The newer 04 LS Calipers look pretty sick in that gold color though.....
