i have the is250 brakes in my car and was hoping to get the is350 big brake 4piston caliper upgrade. will my overall offset change if install this on my car? i'm worried that it won't clear my wheels. also, are the diameters or the is250 rotor the same with the is350 ones? so i'll know what particular items i need to buy from swell.

i'm just making sure because i just got a 6piston monoblock brembo kit for my car and it won't clear my present wheels mainly due to the wheel face. i didn't get the bbk friendly wheel face because i want more lip up front. i need around 25-30mm spacers just to clear it so either i change my fenders or wheels or sell brembo then just settle for the is350 brakes. i think i'm just going for the 350 brake upgrade so i won't need to change my wheels. hope anyone here can help me out. thanks!
epic fail brembo (looks really nice thou if it cleared:

The overall offset should not change unless the thickness of the rotor hat is thicker on the IS350.

Do you know anyone with a IS350? They should be nice enough to let you try your wheels on their car to see if everything clears okay.

if you use a is350 brakes you need 350 rotors , 350 backing plate or remove it , pads ,shims and pins. Also may need a spacer of 5mm or 10 mm but may not need it what so ever. I had a 5mm with isF rims to clear is350 brakes ,but now with 2 set of vossen wheels no spacer need it .

The IS350 calipers are quite large. If you needed 25-30 mm spacers to clear the brembos, it's highly likely that you're not going to clear the IS350 brakes either.

thanks for the replies! damn.. this sucks! i don't know anyone here who has is350.. the the lexus is here are 300 only.

montgb/lexusis305,
do you think i will run a thick spacer? 5mm can do but anything bigger than that will not do for me my wheels are poking out already

Any replies you get would just be guesses - that's not the right way to do this. What you need to get are some BBK templates from vendors - these are paper cutouts that you use to see if the calipers will actually clear. I got a set from KSport before I purchased my 12-POT BBK from them.
