Just for the sake of curiousity, what would it take to do this? Spindles, wheels, brake centers, axles? I've always liked the looks of it on the F40, F50, Enzo, JGTC cars etc. Again, I only ask out of curiousity. I know there are better ways to waste money. Thanks, Ryan.

i too love that look, but the government does not lol. though there is a rim company out there that sells a 1 lug wheel ( torra wheels). torra uses a adapter plate that bolts to the stock hub of the vehical then has a spline out for the wheel. anyways back to the subject at hand,



the true one lug is not leagle to use on the streets as far as i know and if it was it would coast a **** load of money to do so.

I'm sure it's legal. Otherwise Ferrari wouldn't have been doing it for more than ten years. Plus a friend of mine said he saw a vette with this type of thing done. It does seem like something that you'd want to make sure you're torqued properly.

The torque value for the single nuts is like 250 ft/lbs on most cars. Hope you dont get a flat out on the road!

Doesn't really matter when you don't even have a spare https://www.nopistons.com/forums/pub...#>/biggrin.png That's what AAA is for. It would make for a nice wheel lock though.

I am kinda partial to having five fasteners per wheel to hold them on as opposed to one per wheel...

93 R1 03-06-2006 10:09 AM

Its actually alot more then 250. The Carrera GT is somewhere around 600 ft/lbs.

saru-kun 03-06-2006 12:34 PM

Hmm....the last time I torqued down on a single lug nut was on my boss's GT3 Porsche...the setting on the big ass torque wrench was around 450'ish N m. And the socket size was close to 30mm....I forgot...haven't been wrenching in awhile *sweat*

Yeah I thought it was way more, but i didnt want to be like "yeah you have to tighten dem bolts to like 3990ft/lbs" without being sure, so i lowballed https://www.nopistons.com/forums/pub...IR#>/smile.png

HOLY DOGSHIT! I never noticed it on the carrera i looked at. I was more amazed by the body.

jspecracer7 03-07-2006 04:36 PM

450 ft/lbs. ****. I don't want to carry a 6 ft. breaker bar to get my wheels off.

22GoinOn2 03-07-2006 05:42 PM

I'm really not concerned with the practicality of this type of modification. I'm only curious as to what parts on the car would have to be swapped out. Torque settings don't mean much to someone who doesn't honestly plan to go through with it. Besides I doubt it's that high. I'd imagine that 250+ ft lbs would be impossible to break free with an air rachet which would defeat the whole purpose of quick changes in the pits.



Would you have to modify the rear axles at all for this type of set up? Thanks, Ryan.

89 Rag 03-07-2006 06:09 PM

Ratchets go to and through 800 fpt and the ratchets they run at the races are nitrogen powered.

Still sounds like it'd break your arm trying to hold it steady.

apexkw 03-07-2006 09:11 PM

i talked to a bunch of people about this a couple years ago and the only place that could do it was pettit and they wanted a $1000.00 per axle. i said holy crap thats alot and said forget it. also not only would you need the conversion but new wheels and new rotors for the brakes.

j9fd3s 03-08-2006 04:14 PM

my tr3 has knockoffs on it, its got an adaptor that bolts where the stock 4 lug wheel would mount, and then its got a splined extension so you can slide the wheel on.



the "nut" has ears so you hammer it on and off

#76 if it matters.



setup is probably totally unsafe, as is the rest of the car

saru-kun 03-16-2006 09:17 AM

rfreeman27, sorry about that...was working on the 996 GT3 cup car then. All came with single lug nuts ^^



And it was 450'ish Newton meter. Not foot pounds.



22goinon2, yeah...I'm skinny...and I shook pretty badly with the bloody airgun hahaha. And it was branded stuff too!!! SP Air... lolz



Cheers

ive seen cobra kit cars w/ real knockoffs but they still had 5 lugs, but they were short, more to steady the wheel, and then the literal knockoff (with a hammer like j9 has) and that keeps it tight
