Re: My 1990 ZR-1 #2342 from SPAIN.
I'm here again! Hi!!
During 2.020 I decided to solve the problem with original plastic air duct inlet. When your are pushing hard with "pedal to the metal", the duct collapses and the car loose power. When you return to normal speed with no hard pushing the problem disappear. My original air duct was arched to inside center part. Thanks to my good friend Jerry from Jerry Gaskets I could solve the problem with Silicone Air Duct. After installation, the problem of collapse never came back and I could enjoy maximum power without restrictions. A few pictures...

Re: My 1990 ZR-1 #2342 from SPAIN.
Good morning again?. Today let?s talk about brakes.
During 2.021 I decided to improve brakes because original rotors were still in its place, with a lot of wear, and Road House brake pads installed by last owner were a big trash (negligible braking power with infinite brake stop distance). Bad brake pads with weared rotors were a dangerous combination for ZR-1 performance. After looking for alternatives always keeping original style and original calipers but improving quality with modern materials, I decided stay here in Europe to obtain all parts from EBC Brakes in UK. Two complete kits (rotors plus brake pads) for both ?axles?, front and rear. References are: Front Rotor D7009 with Pads DP41131R. Rear Rotor D7008 with Pads DP41167R. Here you have front unbox pictures:

Re: My 1990 ZR-1 #2342 from SPAIN.
That's all!
After few weeks and more or less 1.000 km (621 miles) of peaceful driving to settle rotor surface and brake pads, my new EBC YellowStuff Kit began to show all the improvement. Braking power and feelings are now in consonance with ZR-1 performance. In a few meters you can stop the car with confidence (before with Road House Brake Pads and original rotors was impossible). From the installation until now brakes become better and better. Just now I can drive in any conditions with total confidence on my EBC's independently on your speed rate. I'm very happy with results. It will continue...
