beginning my F conversion journey!

 

Nice!!!

Get rotors directly from Brembo a lot cheaper than from Lexus.

 

i wish i saw this before ordering them yesterday🤦‍♂️i paid $171 per rotor but got everything else for the same price as you did! thank you for posting all the part #’s and where to get them it was a big help. hopefully doing my conversion in the next couple of weeks

 

Who has your RR Racing brakes now?

 

and done! loving them so far. comparing them to rr racings kit (wilwood calipers & rotors) i would say the rr brakes have a better bite, but tend to have a lot of fade and on certain days the bite was off. overall this is oem which is what i wanted and of course the F brembo orange combined with ultrasonic blue!

 

To the OP thanks for the work and for sharing. I can’t seem to find them in any other color but orange. To “jmull3r” how wide are those 19’s and what offset are you running. I can’t decide if I want to go 18” or 19” which will also determine if I go with the oem Bbk. Your guy’s cars look good.

 

Checking to see what the long term reviews have been for doing the GSF upgrade vs ISF Caliper upgrade? Is it an upgrade that you regretted or would do different? As in terms of fitment of the factory IS350 wheels, Will they fit back on for winter wheels or do you need to run a spacer on them? I have a brand new set of LC818's with Continental DWS06 off of my 2G IS350 I just recently traded for a new Infinity QX60 Limited. I stripped everything off of my IS350 when I traded it in with plans on trading my wifes 2015 QX60 in for 2019-2020 IS350 at the end of this summer and swapping cars. Original plan was to buy New ISF calipers with the GS350 Cross Drilled Rotors for the front and be done but then I stumbled across this post and found that the GSF Calipers and Brembo rotors are very cheap now, look way cooler but I will be limited to running my LC818's year round. My biggest concern is bending a rim here in PA and not having the OEM wheels and tires as a backup but that is the trade off. I have not fully committed to buying another IS350 yet because my kids are both teenagers now and hated the size of the IS350 and I might go with a GS350 F-Sport this time. I'm really leaning towards Jmull3r's setup since it seems to be a cleaner setup with all OEM parts and can be used on both IS350 and GS350's..

 

Hey guys, I’m new to the 3is platform. Has this conversion been done on awd models? If so, is there anything different?

 

No difference works the same RWD/AWD. You'll need the bracket for the rear and shaved dust shield. Front bolt on but remember withe GSF/RCF you'll no longer be able to run your stock wheels. As the front will only clear 19"+ size rim. If your like me with AWD and swap summer to winter setup. Go with ISF front and RCF rear caliper. To fit the ISF up front you'll need to get GS350 Fsport rotor must be Fsport or it be to small.

 

Thanks! I do run winter/summer sets. So I will look into this setup. As I’m currently running some 18x9 et38 for my summer set. And of course the staggered Fsport 18s for winter. Someone may have asked this on this thread already, but how is this upgrade compared to the 350 one??

 

Good to know. Would love if this would fit on 18s because I have a set of advan TCIIIs that I love. The color combo looks great on the blue which is the color I have but looks good on the black and white.

 

So after a few minuets of digging. You get the same look with ISF Brembo. Should clear 18” and f-sport wheels.
