callipygian 911

Sometimes I like to stiffen the boby by twisting. It's not that unusual.

I took this elephant x-brace for a test drive this weekend at the track.
leaving the strut brace mounted, the difference with the x-brace and without is very noticeable, maybe even substantial. initial turn in is more precise and quick.

the front bracket screws into existing fender mounting holes, no drilling.
the bracket would force the frunk carpet to stick out if you still use a carpet.
the bracket is also very slightly in the way of the headlight release but not enough to cause a problem.
brackets, hardware and tubes are all very nice and high quality. also looks very cool.

Very nice. But the downside of this is not being able to change a baby diaper in the front-trunk anymore!!

I like the install, however for my street car I have been reluctant to tie the two sides of the car together. In the event of a front 1/4 crash the brace will transmit force to the other side of the car potentially increasing the extent of any damage.

maybe its just me, but the use of a sheetmetal screw in the front doesn't seem like its ideal for stiffness.

Also, can you still use the trunk trim panel piece with this in place?

thanks

Very trick pieces! I like!

Thanks for the info. Looks like there's going to be another thing added to my list

the baby will still fit and the bars could be used as a rack to hold diaper, wipe cloths and such.
the plastic trim piece would need to be trimmed on the sides to fit and the carpet would need to be cut and trimmed all over the place.
but I don't think the product is marketed for street use, maybe a 50/50 street/track use, but mostly a 20/80 street/track car.
I can fit my small tool bag or a baby between the bars, but not much else.

the front bracket screws use the speed nuts that hold the front wings to the tub, it seems to be a solid mount.
I don't drive over the curbing in my 993 like I would in a miata but I still miss often enough and hit the rumble strips on exit and after 3 track days the front brackets are still tight.

It looks like most of the forces on the cross braces would be compressive, so those little screws aren't really taking much strain.

How much is this brace?

$580 directly from Elephant Racing. No affiliation, I was just looking at their webpage.

its pricey, but it looks very nice. its definitely on my list.. it would look great painted body color too.

on the elephant site..does the "935 X QuickChange Strut Brace" include the single strut tower bar? or is that only the x brace part of it?

Is there a huge difference between this brace the RUF strut tower brace that I have that is not an "X" or is mine 9/10ths of the increased rigidity just connecting across the strut towers? That is just what I am imagining.
It would be interesting to actually measure the difference in deflection via bending and torsional rigidity through out the body with the regular brace the x brace and lastly, no brace.

I've never noticed any difference with a bolt on product; initially when we could only log with lap times, and now with hard data. Properly engineered cage? Wholly different.

(My cousin prototyped many versions, which I tested in the '90s and '00s on various torsion bar and 964 chassis.)

my description of 'noticeable' and 'maybe even substantial' are based on friday's test and tune track day running without and with the x-brace.
I already had a strut brace installed so I left that part in place for my testing.
I'll disagree with ken here, I think installing a bolt on strut brace or a bolt in das roll bar can be noticed right away.
I was busy between sessions so when I got out with the x-brace installed I'd forgotten about it and my first thought was that my alignment had somehow changed.
the noticeable difference was on turn in especially in one tight corner. it felt like front toe had gone from zero to maybe 1 or 2 mm toe out.
and if I just muscled the car into the corner because I turned in early or late the front tires scrubbed badly. this makes me think that the stiffer front amplified my mistakes.
the maybe even substantial difference is my best lap was 1.2 seconds better than last spring on this track configuration, same car, same tires, same driver.
I'm not saying all that time was due to the x-brace, some guys came out in june to compete in time trials and just running against them improved my driving.
that is why I qualified with 'maybe even substantial' rather than substantial.
worth the money? for me yes, I have no idea for others. I wouldn't bother buying one for my street car but I did bother buying a perfect power strut brace for my street car.
