You guys also should make sure your wheels clear the big brakes, especially up front. This is a 'surprise' extra expense for many folks who purchase upgraded OEM or aftermarket big brake kits.

i think they mentioned in the thread that these brakes will not clear with stock wheels.
I am suprised to hear that since the stock 3GS has some beefy 4piston calipers already, I can't imagine these are that much bigger.

^ Doh, didn't see Luis' post on the 2nd page. Logic would assume that the stock rims wouldn't clear, just needed confirmation. The ISF brakes are much bigger, front disc is 1" and rear is 1.5" larger than our GS, in fact the rear disc is larger than our front disc. Plus the cross drilled discs and the logos on the calipers add that extra bling factor. . .

Aftermarket wheels that fit big brakes are often referred to as 'high disk' design and depending on the brakes even some of those don't fit without a spacer. Those with 'low disk' have bigger lips on the wheels.

i posted in the vendor forum but will mention it here as well.
the is-f brakes (front) is 14.2 rotors, and i believe brembo makes the calipers for them?
the oem calipers on the gs, is, and ls460 are HUGE. in fact, they are larger than some aftermarket brakes out there. for example on my ls460l, my brembo brakes actually has more clearance on my wheels than the stock brakes. that's how big the caliper is.
of course, i can't say with 100% guarantee, but i am posting from my experience
in fact, i am not sure about the overall diameter? i knoe 14" setup needs at least 18" wheels to clear. this is 14.2. maybe still ok, but not 100% confidence
for sure this is one very interesting mods cosider it's so affordable.
btw, tommy, your 20s? you have zero issues

Henry, So are you saying the IS-F front brakes caliper size is smaller in size than our stock 4piston calipers? If that's that case i will get the IS-F brakes.
One thing i'm concern is brake dust. I'll wait for the IS-F owners to give feedback before jumping on the GB.

I think Luis mentioned someone doing a test fit. As Henry stated, the stock GS 350 up 4 pots are huge. THey are good brakes from the factory.
The IS-F caliper looks longer and possibly not as wide. Sounds like it will easily weigh much less.
I think another reason for the low price, the IS-F brakes while huge, are not 2 hat rotors, but a 1 piece design. Brembo started offering this setup a couple years ago as its cheaper than the setup DaveGS4 has for instance.

Tommy,
you were the one that told me you don't understand why people with 3GS get BBk because the stock one is already like a bbk with 4 piston, don't bite into the temptation
and yes, brembo is notorious for having massive amount of brake dusts, i am sure is-f is no exception

You know i got the MOD bug going on. Besides the price is very attractive. But I cant really decide right now. Its either JDM Lexus body kit or BBK. Both are about the same price.

Guys one more thing i think we should really all consider before buying the IS-F BBK.. Make sure your spare tires will clear them. God forbid you get a flat tire in the middle of nowhere. (knock on wood). You dont wanna be stranded in the middle of nowhere or in the fwy where help is not reallly accessible.
