Rear Wings?

[KevinSA]

I would seem e30pq has mounted the uprights to the rear chassis making for far less flex.

[SA E30]

I think the triangulation reduces the flex while the uprights mounted to the chassis transfers the loads more directly, making the wing more effective.

So is your upright one piece?
When you need to open your boot lid do you have to remove the wing?

Yes and no. If you want to remove the boot lid you would need to remove the wing but we don't have much in the trunk that needs our attention.

The battery is still in there but we have a jump point under the hood if we need to jump start it.

We did a rear shock adjustment at the track last weekend and we did it with the wing still installed. Just unhooked the 4 pins and held the lid while the other person did the adjustment (2 man job).

If it was me i would have the uprights coming off of the license plate area, although the further back the wing the more its going to hurt front end grip

Unfortunately, the BMWCCA rules limit how far off the back bump your wing can go. It would be very difficult to adhere to the rule and install the wing off the back of the car.

[e30pq]

Yes and no. If you want to remove the boot lid completely you would need to remove the wing but we don't have much in the trunk that needs our attention.

You guys are awesome. Thanks for all the info. APR wings are the ones I have been looking at but unfortunately my budget at the moment is closer to the $100 wings from ebay rather than the $300 APR wings. I am wondering if a $100 wing from ebay is a better than nothing approach, and I am also planning on adding a front splitter to offset the additional rear down force OR should I not waste my time with the $100 wing and home made front splitter.

first question, are you running any kind of data like a traqmate or race keeper?

the great thing with NASA is it allows us to "run what you brung" and experiment with setup. Alot of fun.

I did a homemede front splitter on my E30 and it helped on the banking at HMS, not any faster just smoothed it out a little. My concern with the Ebay wings are them bending at speed, the generally say somewhere on the page that they are not intended for racing.

90mph through T1 you could benefit from a wing, but I would really want to see the data between with wing and with out, on the same day.

ever see that video of the rear wing breaking on a STI in a turn and the car being totaled? Not sure a wing is something i would skimp on

this was not a cheap wing either, it was the APR carbon

I've seen that video earlier this year.

It looks like the driver gets the left wheel over the left curbing which will pull the car left. Does that cause the spin? Once the car rolls the wing is going to break off or get crushed.

I can't remember the thread where I first saw that but my next question would be if the car following (assuming someone was close by) saw the wing break off causing the spin and roll.

One thing I recall about the thread (I think it was Bimmerforums) was that people had a hard time believing that the car was at 148mph.

[e304me]

You can see the wing come off

[SA E30]

I think the wing coming off caused a loss of downforce on the rear. Which the driver didn't realize until he had entered the corner way too hot.

[Good & Tight]

Will a regular factory wing give any down force up to 180? I deff need one but do not want to drive around the streets with such a huge wing. ATM there is no wing at all.

[Hick]

you could drive and e30 upsidedown at 180mph

[e304me]

No, when an e30 goes 180mph it is upside down
