brey-krause new project car

[lmw]

Hey just wanted to share some pictures of the new Brey-Krause track car that we are building. I will post more pictures once more work gets done.

Sweeet, subbed.

What class are you going to race in? and who is doing your cage work?

All the drivers at brey-krause will be driving this car. So we have everyone from instructors down to beginners driving it. I am however a intermediate.

I assume the heim extension is to allow for a great amount of negative camber?

A thing that strikes me as odd on such a beautiful ground-up build is the use of the stock non-adjustable front sway bar. Also why not use standard Nascar door bars and not lose all the cockpit room? I know zip about cage dynamics but it looks like that single bar transmits all the force directly into the X, especially if hit from a low->high angle. Just questions, not meant as criticism! You had me at the Orange Unibody..

I was thinking the same thing(s). why didn't you weld in front camber boxes? and/or go with the 935 control arms? Just curious. I wonder if I could make those control arms from mine by welding on a nut at the end.

I don't know much about suspension.

[Elombard]

Wow all that work and not wide body??

And no coil overs at the rear?

And the clock still in there :-)

That front control arm mod is pretty similar to what they have been doing in SCCA production car racing for years; except how the strut fits into the bearing. Wild.

Looks fantastic just interesting choices. IS it just a DE car?

[Oh Haha]

Sweet!

Are those RUF flares in the rear? Sneaky, if so.

Car is being built to a simple spec. We want a car that we can run economically in drivers ed...perhaps 911 spec racing...and be a platform for our engineers and younger drivers.
I like old school simple cars. I like to use real engineering to dispel "conventional wisdom". I think that people should learn to drive in cars that do not do all the work for them.
We work with several capable race teams. Peter Dawe is prepping this tub. He is very very good and understood our concept. I promised not to tell who is doing the engine and finishing the setup.

What year of shell did you start with?

Great looking car, but I too wonder about the use of some of the parts in such a high quality build..... but to each their own and it appears this car was built with a particular vision and that appears to be met.

Interesting use of the rod end, is that the shear they are designed to see?

Cheers

I'm interested in the control arm too. It looks like the balljoint stud is welded to the heim joint, is it? Does Dawe have any racing experience with that set-up? I have been thinking about lengthening my control arms myself, or sending them out to Fabcar. I would like some adjustability but can't justify the cost of the ERP 935 arms.

I agree with some of the other posters regarding part choices. I would think you would want adjustable swaybars at a minimum so you have some means of tuning the car at the track. The good thing is if you decide you want them later on the are easy to add. Nice fabrication on this project, you've got a great foundation.

[GaryR]

It's the shear on those threads that has me wondering, but if an engineer that knows the forces involved designed it all should be ok... I use curbs a lot though.

Agreed - it looks the shell had a thru-the-body mount already and the non-adjustable was chosen in favor - what size is that bar - looks like the RUF bars I have on my 84 - where did you get the bushings? The largest OEM bushings require some shaving to work -

I agree that some things are simple but that suspension setup doesn't look simple to me - talk about camber possibilities - would like to hear Chuck weigh in on this -

It's generally looked down upon in engineering but can work with an oversized heim joint. Off-road trucks and buggies do it all the time and they experience loads that far exceed the average track car...

There are so many directions to take when building a car. Many decisions were debated others were just made. The concept was begun with building a safe, fundamental car. One that would provide a good learning curve for a 911 novice, as well as a car that could entertain an experienced driver. The car was to be a non-wide body, 915 gearbox, and torsion bar 911. Nothing was really set in stone once the project began except for those parameters.

The tub (I believe) is a 76. When it came to BK it was a retired club race car. We cut the old cage out and dipped it. It received a ton of restoration when the cage was being put in. Some of the pictures show example of the rust damage. The car actually got a nose job from another tub, stitched together just forward from the towers.

The lower ball joint concept/design has been subjected to race time. This is not the first set Peter Dawe has done like this. The sways are staying in stock location, what they will consist of is…
