    This is the only one I can find. This happened at approx 175 mph as the car transitioned into the downhill braking zone leading into turn 10a at Road Atlanta. I had the wing for 3 years with no issues, but that is the first time the car has gone this fast. The wing was a plain weave carbon leading edge with two layers of unidirectional carbon followed by 5 layers of fiberglass cloth, cured under vacuum. I didn't notice and stress cracking or anything following the event, and had recently done shake down testing up to 140 or so without issue. My gurney flap you see there is 1/8" thick aluminum angle, and it bent like it was nothing. The top plates on the wing upright are bent also.

    Next wing will have solid carbon spars and will be several layers of carbon twill over uniweave. Live and learn.

        That's intense. Was the wing normally more inclined?

            Who knew one of these bricks could go that fast?! Ever consider racing old Volvos?

            Did it try to take off at that point?


            I remember as a kid reading my road & track, when the Ferrari Daytona came out it could do 175 stock out of the box. "NO. F-ing. Way." we all said to each other.

              No, I typically have run a low angle of attack. The straight line speed is what I seem to need in this chassis. The tires have always done the work in the corners. I am changing the profile and going slightly larger this time. I can afford a little more drag now. ;D

                The aero really helps. Before the flat bottom and diffuser !45-150 was hairy. It is pretty stable over 160 now, but it still feels like something you shouldn't be doing. At any rate, the limiter in 5th doesn't lie. I had more than 50 yards of track left, so with lower gearing, who knows? I'm not going there, though. Especially living that 4 lug lyfe.

                    Talking to Lee at Massive right now about upgrade options. She doesn't stop well.

                      Stopping is good.

                        Dude I feel your pain, I have rx7 calipers and stock brakes in the rear and I can barely stop with just the S54.

                          Lee at Massive is getting me all set up with his kits to accomodate Wilwood 4 piston rears and 4 piston radially mounted fronts on 11.75x1.25 rotors all around. Those, some G-loc pads, and a big ass new wing and we'll be in business.

                              Thanks, it's been a ton of work. No clean laps, unfortunately. I'd like to know what it can do as well. I think I ran a 1:39 on an outlap.
