I haven't done it yet but will screw bolts into the end of the hoses. I am looking for some duct/vent inserts to fit into the holes in the bumper and dircto the air to TBD. One member welded the plastic and repainted the bumper but I don't have those skills.

I found this last week and turned out to be an interesting read... you might find something helpful in here since it seems you're going for track records with all the weight reduction.

Added Cusco lower brace
More chassis stiffening is good. The Cusco Lower Brace for the GS fits the SC and replace a weaker part. Some weight gane but will contribute to better handling.
See for example Vividracing ... Cusco type II Front Lower bar Lexus GS400 JSZ161 '97-05
Was special order from Japan. Came in about two months.

Upgraded coilovers with Swift springs
More on the handling improvements.
I was riding on Megan LP coilovers and the springs were a bit too soft for aggressive corners; still some roll. Went to stiffer Swift springs - called Swift and we went to 12 in front and 10 in the rear and changed the length to be the same front and rear.
Have yet to try them out at the track.

Carbon Fiber
I added replacement hood and trunk lid in dry carbon fiber from Seibon Carbon. This in addition to the rear diffuser I had installed. Hood dropped about 15 lbs and trunk about 30 lbs. In the hood I also gained the vents - the large central vents helps pull air through the radiator and transmission cooler. The side vents let out heat from the engine compartment. Using Dash Commander the radiator trmps are lower. The air intake temperature is the same as exterior air. I use the K&N dropin airfilter and I added a BFI addition with 3" duct to the area in front and below the radiator, with a scoop that collects the air coming up after passing under the front air dam.
Details re. BFI are in another thread.
CF overview picture is here:
https://www.clublexus.com/forums/sc4...ml#post9203423
I applied black plastic dip and then painted with base, color, and clear the sides of the trunk lid and hood along the contour lines. Then I used 3D CF vinyl to connect the hood and trunk lid along the vehicle contour. I added CF vinyl tonthe front bumper to end the flow.
More and better pictures to come.

HKS Speed Limt Defeater (SLD)
After the Supra TT LSD 3.77 differential swap, the top speed measured on a dyno was 118 mph. The ECU does not understand the new rear end gear ratio.
See another thread about this issue but I installed the HKS SLD and it works but throws the cel/VCS/VCS OFF lights with code P0980. Even so the car runs well but there us a big drop in mileage. I'll try it a bit more but I am not comfortable with drivng with the engine lights on even know I know what they mean. HKS USA says the product is only supported for JDM cars ...
The Apexi Rev Speed Meter also has a defeat speed limiter function so that might be the option.
