Looking really good Jason

That doesn’t look too big, it’s nice.

Are they the std posts?

Are they the std posts?

Doesn�t appear so, the triangles are the wrong shapes, and overall they’re a bit narrower.

PS. Sorry for answering your question Jason

Eliseparts sell those supports, they bolt to the chassis, unlike the STD ones that bolt on the clam.

Thanks chaps

Thanks guy’s

Yep those are the eliseparts brackets. The wing is a litle bulgy in places, I wasn’t sure if it would work or look nice so did a really cheap one to start with for testing. As you can imagine a carbon wing is not economically viable unless you know you like it. According to my calc’s it produces 89.9kg of downforce at 160km/h, this excludes the gurney flap and end plates so probably close to 100kg. I have set it at a 10 degree angle of attack for now. I doubt I would need more than that. Also it feels alot less draggy at 130km/h plus.

First time I put it in place before painting it I really hated it, but after it was painted black it did not look that bad.

Everybody says that the std ones bolt to the clam and the MS ones to the chassis, when the std ones bolt excatly to the same part of the chassis as the MS one, although without the slot in the clam.

See, the MS ones bolt to the sides of the vertical bracket that holds the clam, and the std ones bolt to the top of it, on the other side of the clam. Same strength, but I assume it was done only for ease of varying the height.

The motorsport ones are designed for the three piece rear clam and to aid quick removals etc. Plus there is less ally involved so it must be lighter.

The motorsport ones go directly to the chassis as there is no strength in the 3 poiece clam there. The three piece clam actually rests on two angled sections of ally that are also bolted to the wing supports.

Ah, so you say those black brackets above with lots of holes bolt on to some other brackets that also hold the clam? Because they would be too short to get to the chassis.

Would it add too much weight to keep the std brackets? they seem pretty strong to me.

That would be correct Uldis, you cannot keep the std brackets as the adjustable wings mount at 90 degrees to the wing. Std wing bolts go up into the wing, plus the std brackets are contoured to the profile of the normal wing.

Yes. On each side there are two elongated triangular (for want of a better description) ally pieces that bolt to either side of the longeron. At the top of these are two pieces of 90 degree alngle ally that bolt to the uprights pieces and form a platform for the clam to rest on (they even give you some foam pieces to use between the ally and the clam. The wing brackets (or the black eliseparts ones picrtured) also bolt to the top of the uprights. Basically two bolts pass through everything mentioned and hold it all together.
