    APR GTC500 Wing

    Hey Guys,
    If you are running the APR GTC500 wing be very careful with your speeds. I installed mine as instructed to the rear hatch cover when I received it last month. It seemed a little unusual to attach it there but we followed the instructions. We ran Roebling Road this past weekend and the car performed incredibly well. I was able to run by far the best lap times I ever have(1:16.43). Part of that was due to the added down force the wing created. It really helped with the sweeping high speed turns and the long straight. The car was steady as a rock with the wing. We ran all day Saturday and two sessions into Sunday. Needless to say these cars road race performance greatly improves with the wing.

    However, at the end of the long straight at about 158mph when you brake hard going into turn one the wing somehow ripped off the rear hatch panel and left the car. I'm not sure what caused this but the transition from WOT to very hard braking created enough upward force to tear it off. It was adjusted fairly aggressive with the down force so I know that part was working exceptionally well. Why the change to braking effected it that much is a mystery to me. Fortunately for all involved when the wing left the car it headed into the grassy area next to the course and avoided the potential track damage. The hatch cover is a loss but I think the wing can be repaired. Anyway, I am hoping that APR will help help with the repairs.

    I'll keep you updated as we move forward. We will be looking for a new mounting point(frame rail) and mounting brackets.

    Re: APR GTC500 Wing

    Sooooooo....

    1. It needs to be attached to the frame :-), as you just learned...
    2. NOT knocking on APR but if I was YOU, I would set aside that piece of 2X4 (wing) and get a true wing from GMG with mounting end plates.

    Any incar video of you driving?

    The wing itself worked incredibly well so I just need some new mounting brackets that go to the frame. I am working on the incar videos as we speak. I'll get some up as quick as I can.

    Got the car out of the body shop Friday and its going to the performance shop Tuesday afternoon to make some measurements and fabricate a new bracket that will go to the frame. I highly recommend the wing but definitely NOT the supplied bracket that goes to the rear hatch cover. That cover is fiberglass and not strong enough for real racing. If you want it for cosmetic purposes then its fine.
    If you are going to race with it at high speeds I'll give you the information when we are done with the new bracket.

    Re: APR GTC500 Wing

    I was the person who actually commissioned APR to do that rear wing. This was a while ago. As I recall, we changed their original mounts right away. APR saw the new changes that we had made, and then changed their setup as well. I really can't say what their eventual mounts looked like. I have tracked my VF supercharged R8 for well over 10,000 miles, without incident. Those speeds are pretty normal. I'm trying to make sense of UR fotos. Unfortunately, my car is not with me right now, so its difficult to compare. Could you maybe do a foto of the place that U believe initially failed?

    Bodhii,
    You can see the mounting plates and where it attaches in the photos above. It did not come lose from the rear hatch cover but it ripped the fiberglass hatch cover off. I'll have new mounting plates/brackets made within the next week or so and I'll share that with you. They will go to the frame. Here is a cad drawing of it.
