I first bought a TCR one as it looked interesting whilst ordering stuff from amain (I am in the UK). I really liked the way it calmed down the rear end and helped during flight, but the plastic was a too brittle with not enough flex in it to withstand any major tumbles. So I changed back to the Proline ones, and it was completely different, with the back end stepping out and everything. So we looked for some more TCR wings, but amain didn't stock them anymore, so we bought 6 from eBay. I have boiled these ones, and apart from the odd imperfection, I have only broken 1 in about 5months of running (the winter was exceptionally cold here).

Also, my Dad works in F1 so took both the Proline, and TCR wings into work, and asked the aerodynamicists which was better, and they immediately said the TCR one. Just a pointer, that to get superior down force, the two elements must overlap about 4mm, and there should be a gurney flap at 90degrees to the top or the wing, pointing towards the front of the car. This will increase drag slightly but will allow a LOT more down force. Plus the parts that stick up in along the length of the wing (not sure what they are called) should be full height, to give more cornering stability.

I am weary that if I get comfortable with the TCR wings that when I have to return to Proline, I will not be happy with it. My only qualm is that the plastic needs to be more flexible.

Is TCR distributed to the UK? Or is it solely America. If just America, then I think you should consider exporting to the UK, as many people look at mine, and ask where I got it from, and are interested in it due to it's radical looks.

Hope this helps,
Scott

Just wanted to add my findings from yesterday on the matter. I was running the stock AE wing, my car was nosing bad on the jumps. Changed to the JConcepts HD wing and it completely leveled my car in the air. That was the only change I made!

About halfway into the A-Main one of my wing screws pulled out and my wing orientated itself in-line with my body, after that I couldn't keep the rear end under the car.

Jason for j concepts like i said is an innovator and a great designer thats why he uses the holes on the back of the wing they create suction like the ventouri effect which stabilizes the wing on both left and right areas of the foil.

He has done this because its a one piece wing not two piece so the only way to stabilize the wing was the two holes put in place inline with the channel airflow channels that have put in .
