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?

To tell you the truth, I have no idea..I guess in a week or so I'll let you know what happens....

Not to hijack this thread, but here's my DSR UCF-30 conversion on my Aristo V300. I believe I am the 2nd one on CL with this setup.

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.....
