Hi All,

I am considering upgrading my brakes because I am thinking about getting some bigger wheels, and as it is right now, I feel like the brakes are just a little "soft". I have a 2013 AWD F-Sport, therefore I did not get the 4 piston calipers Also, I am coming from a 2008 Audi A4 which is significantly lighter than the GS, and well felt like it had better braking ability. Any how I wanted to get your guys opinion on a few things:

1. Could my issue just be brake pads? I bought the car used with about 18k miles on it, so I am guessing it still has the same pads that it came with. Will a good set of ceramic pads help?
   
2. Sewell has F-Sport calipers for the RWD listed for around $600-700, is the upgrade to these calipers worth it? Has anyone done this? Is it even doable?
   
3. I was looking at StopTech BBK's but didn't see one specifically for the GS, are there any out there? I know these will definitely make a difference, but at almost $4k they are a bit pricey, are there any other BBK solutions out there on the market, besides Brembo and StopTech, that are a good bang for the buck?

Thank you!

From what I understand the fsport 4pot caliper is made by stop tech...these do the job great for a daily driver, I'll just be doing stainless lines and call them good to go...if your tracking it often then go for the bbk..

Nice thanks man! Maybe I should work with a fabricator and get mounting plates for throwing the stock 2 piston calipers on the rears, and upgrading to the 4 piston up front - call it a BBK

Where are you getting the SS lines from?

Custom made....my tire shop has a guy...

I belive it also has bigger rotors all around also. I know the fronts on mine are a 2 piece rotor so don't know what cost you'd be looking at check out Sewell for pricing...

Lexus website is actually wrong, all GS350’s come with 4 piston front calipers and single piston rear calipers. The design is a carryover from the previous generation.

RWD F-Sport caliper design in slightly different as the calipers are now extended to accommodate a larger rotor.

I see why these is so much misinformation as Lexus marketing didn't get the memo and have this wrong on their website.

You should try a more aggressive replacement pad, and brake fluid changed to eliminate moisture in the lines.

Wow thanks, good to know!

StopTech's aftermarket setup is 6 front / 4 rear.

Sexy - what did it run you?

to make a correction here the calipers are not made by Stoptech, the complete brakes are made by Advics, and they are the OEM manufacture for Toyota and Lexus.

To me, the oem f sport brakes aren't that great. Go for aftermarket front.

Way to much miss info on this site to even begin to figure what is fact and fiction...I've must have seen half a dozen different makers of the lexus brakes I give up sorry if I was mistaken...
