Does anyone know if the TRD Big Brake Kit for the IS300 will fit a GS300? Any feedback would be greatly appreciated.

I think the TRD big brake kit is just the Supra TT brakes rebadged. Either way, it should fit since the front brakes on both the IS and GS are interchangeable. Just make sure your rims will clear the bigger brakes.

Can anyone confirm this?

Post a link to the TRD IS big brake kit and we'll take a look. I think Jeff is correct... TRD rebadged the Supra TT kit for the 2nd gen GS at one time.... suspect its the same.

The TRD Brake Kit on L-Tuned parts I think is the Supra TT Rebadged Kit you are referring to. The kit my friend has is different. I'll take some pictures and maybe you guys can help me identify it. It's definetly a TRD Brake Kit and it sas for IS300 but it's not the Supra TT Rebadged. Did TRD make a different kit? We work for Lexus and ordered this directly from the TRD Dealer Accessory Website.

It's possible they rebadged the LS400 monoblock aluminum calipers. They're about the same size as the TT brakes and also 4 pistons.

Probably the Brembo TRD kit? I found this pic a while back but never seen in real life.

That's the kit he has!! THANKS!! anyone have any info on this kit? and how I would get it to fit a 98 GS300?

I tried to get this kit to fit a 98gs300 and none of the mounting holes line up. I'm afraid that we would have to change the hub/spindel to is300?

If he can't get this to fit his GS300 he wanted me to ask around if anyone wanted it for $2500 non negotiable. $2500 is our cost and we can't return it back to TRD since it was a special ordered part so we're kinda stuck with it if we can't put it on. We would love to put it on though! is there anywhere we could find alternative mounting brackets?

The IS and the GS front caliper holes are lined up differently. The calipers are NOT interchangeable without modification.

The pads and rotors are the same.

Does brembro make a brake kit for the 98 GS300? Could I possibly just order the mounting brackets for a GS300 to get this to fit?

You might try posting it up on IS.net. You will probably get a lot more hits there.

Nightpager, a company in Japan sells brackets that allow LS400 calipers(which are actually the TRD IS300 BBK) to bolt up to GS300. The bracket is actually an RCA that allows part of the GS suspension to clear the LS400 caliper.
