Circuit/Time Attack. The rods actually connect through to metal plates behind the bar. There are also chassis connected supports just behind the lower edge of the bar, 2 to the centre and one either side and some aluminum angle for structural reinforcing. The front section connects to the rear section of my Beatrush undertray. Total weight including all the hardware is 17 lbs. I've completed 4 track days with this set up now and 130 - 140 mph no problems. Lap times dropped by >1 second per lap so far and through the fastest sweeper at the track corner speeds increased >6mph. Some in car footage here

Yeah wrx2evoix, that diffuser is almost exactly what I had in mind for my car. Do you have photos of your solution for the exhaust area?

To get around the exhaust issue I have a main section and a smaller section with a "bridge" connector. This is what it looks like from above



This was it fitted before I painted it, showing how it fits with the exhaust.

Thanks for the pics, that clears it up. The "bridge" is simple and light, nice work.

Wasp composite built my splitter and is extremely strong. I was able to mount the splitter with no front support in the front and able to stand on it. I'm 230 lbs. Splitter is held on by 2 bolts in the rear and 3 1/4-20 button head bolts up front in the L bracket. Install is about 5-10 minutes. Also, from what I have read diffuser should be in the range of 7-10*. Here are a couple pics. If you are looking for a carbon fiber splitter hit up wasp composite. You can check them out on Facebook. They have some Time attack cars running their products.







This pic is of the diffuser at a 18* angle.. We were getting some loose aero at buttonwillow going around riverside. It has been adjusted to about 10* now.

^^^whoa!!! Nice. What are you doing for brake cooling with the side areas blocked off. I relocated my oil cooler as well and I like the block offs.

I am using binary (sn: JID2) brake cooling kit. I have the holes in the headlights for the ducting. I was one of the first guys to get the splitter as he designed around mine but I know it isn't much more that the APR and is probably 3 times stronger. He uses a 1/2 high density foam core with 12k carbon fiber. He also made the canards too. PM me and i'll see what pricing i can get

Will do. I don't like how the APR piece mounts.
