Lexus parts website says need 18 inch wheels for theese. I dont know what is the part number for f sport caliper. Just looking whats on website.

 

Don't you have to change the Caliper mount to go from Non F to F Sport?

 

caliper itself is taller, has longer legs

 

So uses the same?

 

Yes its bolt on

 

heres a example from a person who installed them on gs350 awd. Page translated in chrome.

 

Front GSF brakes are also bolt on on the GS.
Except the dust shields. They dont fit.
also from negatives they are heavier ( rotational mass) and can impact acceleration.

 

Interesting. I did know they both fit, but I thought I read somewhere it required a special bracket made.

Now that I think about it I think that was to do the ISF brakes. Thanks for the info. This will be my next upgrade on my Lux, done the NO Squeal way.

 

You need a bracket for the rear calipers.

I wish I could put budget bigger brakes on my car. RWD F-Sport, GS-F, whatever.

 

Why can't you?

 

I was all set on doing this with the blue 10th anniversary RC-F calipers, I made a parts list if you want it, but I abandoned it when I realized you lose the spare tire. You also need to check that your wheels will clear. Not all 19" wheels will work. Other negatives are the weight and obviously cost for new rotors. There's no real benefit on the street, the OEM setup can lock up the wheels just fine and stopping ability is transferred to the tires.

It's essentially a cosmetic mod which looks fantastic but with too many practical downsides.

 

I'm only talking about doing the GS F Sport Brakes. I have the F Sport 19 wheels. So the GS F Sport Brake upgrade should work without any of those problems.

 

Back to ask for clarification. So from the Base 13" Rotor to the F Sport 14" Rotor. To put the F Sport brakes on the Base/Lux RWD. The Caliper is the same? All you need is the 14" Rotor and different pads to install on the Base RWD?? For the Front Brakes?

 

I don't think so. RWD FSport caliper looks bigger than the non FSport one and they look different.

Just look at BM's caliper and compare it to the FSport one above, they don't look the same at all.

 

It's 100% a different caliper. Just took the below while changing brake fluid, there's no room for a larger rotor without changing the caliper.
