We are doing a bit of work on this Lexus ISF. One of the projects for this Lexus was a Brembo Gran Turismo Kit which included 6-Piston Monoblock Front Calipers and 15" 2-Piece Cross Drilled Rotors with Stainless lines for the front. The Rear is a Brembo 2-Piece Cross Drilled Rotor which retains the parking brake and re-uses the stock Brembo Caliper. We had Stainless Steel Brakes Lines made for the rear. The new front Brembo Caliper with pads weighed about the same as the stock Brembo Caliper with pads, however, the new Brembo Caliper provides a pad surface area about 20% larger than the stock pad and going from a 14" rotor to a 15" provides a greater lever arm for more braking leverage and allows greater heat dissipation. The Stock Front Rotor's weighed 25 lbs each, the new 2-piece Brembo Front Rotor's weighed 19 lbs each. The Stock Rear Rotor's weighed 21 lbs each, the new Brembo 2-piece Rear Rotor's weighed 14 lbs each. The brake pedal feel and overall braking performance of this new set-up are excellent.

We also lowered the car slightly with new Eibach Springs and some new wheels are being built to really show off the Brembo's and should set things off a bit more. Here are some pictures of it now, will have more to share later with new wheels and some other additional modifications.

 

That is looking good. Can you pm me a price for that setup. Just the brakes and not the custom blue calipers. Thanks.

 

Thank you. PM sent.

 

I have a GT kit too, 380mm front (6-pot) and 380mm rear (4-pot), (34/28 ?) but could you tell me the minimum thickness for the rotors, please? Pm will be fine.
Cheers!

 

Amazing work Gary! Thank you for your contributions to the 6speed and Lexus community!

 

Very nice!
