Yeah, fair enough. But the ones which came with the car from factory lasted 45k, and assume are the same Textar brand.
For RCF, I know that they come with Brembo which, as far as I know wears off quicker, and of course bcs it’s a heavier and more powerful car.
Just wanted to share my experience while replacing the rotors. As you all may know the RC350 F Sport models have 2 piece front rotors 356mm. As this is an unusual and quite big size there are not too many aftermarket manufacturers making these rotors. I have researched for 2 weeks and visited multiple racing workshops and parts stores and the only option in Australia is the DBA T3 5000 series slotted which are made on order and cost around $1,500 per pair.
Obviously, Lexus AU took advantage of this and they sell them at $1,400 per pair.
The alternative I found is to order the Lexus OEM parts from Lexus dealers on eBay in UK or USA which ended up to be $850 (AUD) per pair, including GST and international shipment.
Hope this provides some guidance to everyone who needs to replace the rotors in the near future.
