Wheel studs

[blueberry]

Im intrested, why do you guys use long wheel studs at track purpose?

Im intrested because no one here uses them.

I Have not Figuered Out any reasonable explination for this except wheel spacers. But that causes More stress to The bearing and studs.

 

[Bill Pemberton]

You are correct that they are very beneficial if one is using spacers, which is quite common in order to mount wider wheels. The best reason, though is for strength, as you also mentioned and ARP and other Manufacturers make these to high tensile strength standards. They hold up alot better than a standard stud and you can get them from two site sponsors ----OP Mustang and Capaldi Racing.

Quite a few of us have broken off one of the standard studs from track use and constant changing of wheels, so a longer and stronger stud is actually a safety issue also.

Thanks you for clarification, i newer used spacers, i order wheels with correct offset and thats it.

Out of curiosity? Do you run 315 size tires up front??? The Mustang comes alive with fat tires and most of us run square (same size on all four wheels, for example 315/30-18). Also having the same offset on all your wheels allows you to have rotate your tires at the track and only needing one wheel size, very handy and saves a ton on money.

Nopea, i wish i could get 18 or Even 19" wheels to fit over My brakes but nope. I Have got 2⁷5/30 r20 wheels, going 295/30r20

Help us all understand why you need 20 inch wheels since there is nothing listed about a " Big Brake " kit on your " Build Thread." I was running 19 inch wheels with my Mach 1 and it had 15 inch rotors and 6 piston Brembo calipers. Just wondering .......

This winter project Is Porsche brakes, It Will Be on project Part, but everything Is not written at once. You start with The thing you got, and upgrade it from there

19" wheels rub on The Caliber, that The problem. 380mm disc Is too small for them. Why change them, because then i can get Parts in one Day when i need it. As i Have mentioned i Live in Finland .

FYI.
Post in thread 'Rear Wheel Stud Replacement' https://trackmustangsonline.com/threads/rear-wheel-stud-replacement.18654/post-280752

I am also at a loss why you can't run 18 inch wheels. Maybe it would be cheaper in the long run to try and find some Gt500 brakes.

Blueberry, check out Apex wheels. Many of us use them in 18x11 over our 380mm (15") discs. 20" inch wheels are not a great option for the track. Remember the S550 6pot brembos are cheap and will fit on the S197 using the GT500 380mm discs.

You can see the info here

Huge brake upgrade for S197 chassis

Guys and Gals If you don't have $6000 on "magic" brakes here is a potential inexpensive (like anything is inexpensive) upgrade from either stock 4 piston 14" Boss Brembos OR 6 piston 15" GT 500 Brembos----------6 piston 15" S550 Performance Pack Brembos!!!! I am doing full chassis service on the...

I love them and it lets me outbrake the Cayman GT4 cars I run with. You can get complete kits in the US for a little over US$900. Bit its heavy so getting them to Finland could be expensive!! But much less the Porsche brakes!!

 

[blueberry]

The fun Part Is that 20" tires as semislick Is cheaper than 19" here , and there Is actually only 2 options at that size, 20" i get to choose from 5 different tires. But now that you mentioned why 20" Is not good, why... Im taking advice and not causing argument about anything. The problem Is that i was born in The wrong country

Because The car Is street legal our laws about building cars Is not very easy. You cannot use spacers between wheel and hub, its illegal. Because new law i can't put full cage in The car. You can't Even change The exhaust without e approval. If you think california state laws are Bad you can try it here.

Example If i would like to put subframe and control arms to My car i can't Even i would like to, because IT does not Have tuv certificate.

If i order trackpads to here from states i Have to pay cargo, custom and taxes 25.5%. We dont Have them in here at stock. And If we had they would Be expensive as hell.stock pads at dealer costs 300€

Same applys with discs, and The heavier they are The More cargo costs.

For me itse easyer and cheaper to do custom brakes so i can service them. And i dont Have buy The Porsche calibers ive had them for 5 years, all i Have to Make Is The disc center hub.

Again not arguing or causing harm

Actually this is interesting for many of us because folks do not realize how lucky they are until they hear what others have to go through in the Country they live in. I sold some cars to European customers in last years and the sound restrictions, side marker lights , etc. made it crazy for new owners to get Government approval. Can you use racing pads made in Europe since there are some really good ones made there ( I currently run a Ferodo DS 3.12 ). We hope you find some good information here that you are able to use in Finland. Where do you track your Mustang?

2025 Finland tracks called kymiring, Alastaro circuit, Motopark, Ahvenisto circuit and mayby botniaring, YouTube has videos of The tracks. dream would Be nurburgring, gotland ring in Sweden and Porsche Ring in Estonia. Atleast 2 last Will Be for sure, germany mayby but i Have to get every modification on registeration papers first and thats not easy as you would think.

You can get endless,ebc and ferodo pads here but they are between 350-500€ a Set

 

[Ludachris]

Wow. Tall about not car enthusiast friendly. Good for you for trying to do it anyway.

 

[Bill Pemberton]

Having run both EBC and Ferodo , I would go with the Ferodo pads. They are very expensive in the United States , also, but they do wear well and they are worth the money in how well they stop. I prefer the DS 3.12 , though they are the highest price, but the wear and performance is tops!

Please post more pics of your car with the gold wheels and wing. After noticing the second picture in your build thread it shows how much work you have done and the Mustang looks quite aggressive!

When you have a government agency writing regulations on how much noise a tire can make on the interstate...
You may have too much government.

The 18s are preferred here because so many classes run them that there are plenty of race take offs. Also the 18s facilitate race brakes, where the 19s and up are for more " stock" type brakes.. sounds odd, but true.
So I must assume you have access to some machine tools and fabricating facilities.
Seems like welding the spacer onto the wheel, then machining it clean would have an application here.

Yes i Have Access to machines.

At this point of building i am not using spacers, i'll just measure the offset and order wheels with correct spacings.

With My math The More space Is between rim and brakes gives you better heat escape for The brakes and rims.

Thanks for clarification about wheel sizes

The closer everything Is IT produces heat to brakes and wheels. Correct If im wrong but heat transfer Is not a thing i need.

To get back to the spacer issue for a moment, if you are using a quality stud like those from ARP, you can stack spacers on there, even 2 or more. One of the reasons guys do that is so they don't have to buy a set of wheels for the front, and another for the rear. This means the tires can be rotated, as long as the tires the same. This is called a " square" setup. Being able to rotate tires allows you to use up more of the tire until they are corded.
With regards to heat transfer, yes it happens, with some of the Gt3 and Gt4 Porsches. I have worked on you can literally watch the tire pressure go up as the cars sit on pit lane and the brakes heat soak the tires. The mustangs don't seem to have those issues @Fabman makes an awesome set of brake ducts for these cars, and I would recomend them, or something similar to them if heat becomes a problem. I would say generally speaking, that heat transfer between the brakes and ttires are a secondary consideration in the design of the suspension A good set of ducts should nullify any problems there.
I was thinking that the Darkhorse R series uses 19inch wheels, and although I'm not sure about fitment (and they are cast..heavy) they might be a resource for you), they might be a resource for you I would think that a production wheel would be much cheaper than having to make a custom one.
