Looking at some wing possibilities for my IP racecar, wanted to get your opinion on best/max width for IP?

are you gonna make me buy your old wing too?!?!?

are you gonna make me buy your old wing too?!?!?

hmmm, now that you mention it.......:-D want to buy a lightly used rear spoiler :-D

60"

Max width of the wing would be the width of the car at the widest point, not including the mirrors, correct? (I haven't looked at the prepared rules in awhile). I imagine you can pull that straight out the owner's manual, at least you can on E30's I believe.

Hang a plumb line down from the rear fenders next time the car is in the air and measure the width on the floor. That said, I am sure someone on here will know.

Will

thanks i should be fine with 55" wide then

I think you are fine wider than 60 inches. I don't know the exact dimensions, but I think it is a bit wider than 60.

FYI - my E46 is 71 inches wide at the rear fender wells. So my 70" wing fits perfect!!

thanks i should be fine with 55" wide then

You want wider than 55 inches, I believe the stock E36 is ~ 68 inches wide at its widest point. Somebody correct me if I am wrong? We are working on a wing setup, it will be at least 60 inches wide.

make sure you work on the front of the car too

We will have a full solution for the front and the rear to work together. ;)

I'd suggest reading the results from the March RCE Aero article...adding a big wing to the rear does not always directly correlate to more rear biased downforce :)

I'm taking a different approach than most people on the rear wing, it'll be interesting to see how it works.

The underbody will be just as, if not more important than the rear wing setup though, thats where i'm hoping to get the biggest benefits.

For IP though, just make sure you close up all the opening with tape to reduce drag, have a simple affective disposable splitter, and a standard 60" rear wing will do the job very well. The profile of the wing might be something you want to look into though, the more efficient your wing can be (i.e. better d/l ratio to prevent extra drag on a hp limited IP car), you could get a couple MPH on the straight of your copmpetitors.

Very true but with a prepared class car we can't do under body aero. We have some good ideas that we are working on, we are just waiting for our suspension so we can get out and test them. :D

i have a few tricks for under the car as well, that I'm hoping produces results......


Anyone know how much the gt-racing wings are and which one most are using?

For Prepared you definitely want to get mechanical grip first, then add on Splitter/Wing testing and alter suspension to get best results.

The aero benefits are very minimal compared to the overall suspension design/setup.

We run the 60" x 11" Predator. It's not the best wing you could put on the car, but it was a heck of a value compared to other options I priced out. We got the CF version at the price listed for the Fiberglass version on the GT-Racing page.

I run the 70" x 11" Predator wing in CF. Great value!

ltw and ptg replica wings are THE hot setup for prepared...especially IP :devillook

I'll take the new wing on your car then:redspot

so whats the best(not wildly expensive) source for a 60" IP legal wing? GT-Racing?

how about something in the $600-700 range?

perfect, just the element or with end plates?

No, I was asking for recommendations in the $600-700 range, as opposed to the $1500-2000 range

how about something in the $600-700 range?

The fiberglass GT Racing Predator is that price IIRC from their catalogue. We were able to get the CF version for that price through a local Porsche shop.

Their website sucks, i cant find anything, or even a mention of the Predator Wing, even tried to google it but nothing came up

As the saying goes though, you get what you pay for. The profile is not designed specifically for this type of application, and its a fairly high speed wing. Also, you cannot set where it mounts, it just has the brackets where they are and you have to make your own or source your own mounts and make it work.

I'm running a Jaffster Special ;) lol

You have to download their online catalog to pdf file and then look through it. Or just call them and ask. If I remember correctly their fiberglass version of the 70 inch predator wing was $775. Their 60 was a little cheaper - not much, but a little.

So would a motorized wing be illegal? lol

so what would you suggest running steve? Something from pennon or crawford?

Not from Crawford, thats a waste of $2500...

Pennon is $1500 I believe for a "bolt on" setup, still a bit pricey, but you get a very nice setup.

Has anyone asked MAShaw about their Porsche Wing elements? A simple set of brackets and their wing might be a decent combo, but you're probably still looking at ~$1000+.

Its just expensive for a quality wing. They are made with molds, and are time consuming.

If you want it to be worth it, then you have to decide if its worth enough to you to spend this much money.

There are also some wings with quickchange wickerbills, basically a small slot in the wing where you can pull out and slide in wickerbills...can make a noticeable difference in the big picture.

If you have the ambition, you probably could do a little research, find a decent profile (some are on pennon's website), and just contract a small composites shop to do it. If you can find a reasonably priced shop that has experience doing this stuff, it should not run more than $1000.

Unfortunately, composites are expensive, no way around it. The cheap stuff thats mass produced is just that, cheap. The nice stuff that mass produced is expensive b/c they are made in multi-million dollar facilities.

In reality, you would be just fine with the GT racing wing, under $1k with mounts. You just need to dial it in, put a wickerbill on it, and make sure your suspension is setup.

I'd spend WAY more money on suspension than aero for IP. I think a LOT of speed can be found by really developing IP suspension and taking the car to the limit. A wing and splitter will help get you closer to the limit, but it can also hurt you if the "system" does not work together well.

My .02 anyways

I know someone using a gt3 cup element and works well for him. I'm lost as far as aero goes, i'm just looking for something with less drag than the ptg mashaw wing.

1500 isn't too bad, if it has end plates and uprights.

End plates are cheap. $100 and you have a set of two 12"x12" CF end plates. or even cheaper if you want aluminum.

Its the labor of having it mounted if you cannot do it yourself that can hurt the overall price.

Any of these "generic" wing elements used in spec'd race series will work just fine, not optimal of course, but should help more than hurt in almost all applications.

Most importantly try to find out the profile specs for whatever wing you get. So lets say you get Porsche GT3 Cup wing. See what its working range is (angle), what size wickerbills people are using (probably close to 1/2"), and what angle it stalls at.

Also, don't assume adding the rear wing will necassarily always add rear biased downforce.

I'd get the Gt racing wing, and put the rest of the money towards suspension development.

...or just splurge, get the pennon setup and then put more money into your shocks.

We will have one shortly similar to the one we put on Dave White's car. It is an evolution of the predator wing with a profile that is less likely to stall on the bottom and a little nicer construction. Will be under $1500 with some pretty tricky standoffs included.

Any updates on this? Would love to see some pics!

You either get scolded for not searching, or harassed for reviving an old thread! Take your pic... :D

Just step off the wallet and buy a GTR wing from motorsports.... At least you know its working and not just out there.

I would not assume that :) Spec'd wings under regulations, definitely not optimal, especially for the price of those things.

How much are they charging these days? Is it still the standard 12" crawford wing for $2500?

I have 3-4 elements finished now, should have them here next week. More will follow shortly, but I am working out of one mould at this point. We still have to finalize the standoffs with the new elements and that will take a few days. Getting there.

Nice.

Are you making any provisions for mounting to composite trunk lids for all the mod guys, or is it mainly being geared towards Prepared guys?

Mod starts getting a little special order. I really can't build everyone's trunk structure for them. I will make it available without standoffs to work with whatever mounting is needed.

True, sounds like it'll be nice, anxious to see the final product.

Guess I'll get a chance to see a version of it next weekend on the a IP car. Oh by the way, Pro's are supposed to drive in the Pro races that weekend not CR....;)
