Few questions for you guys
How long are the stock 92 SC400 wheel studs?
Where can I get longer wheels studs for the 92 SC400?
How much should I expect to pay for them?
Who makes the best ones(if there is a difference)?

thank you.

 

I bought H&R Spacers and they came with longer studs, H&R makes really good products, we didnt have any problems with them not fitting or spinning

 

my mechanic gave me 1 set of 8mm spacers and just need the studs....

carnal: do you know how long your new wheel studs are?
they are 12mm right?

 

I actually got them for my Maxima I needed to clear my big brakes
they were exactly 5mm longer came with a set of 5mm spacers

H&R specifies that if you lugs dont turn 6.5 turns on a 12x1.5 stud then you need extended studs, check that out see how many turns it goes

H&R specified 8 turns on the 12x1.25 (for the Maxima) to get 10mm of load on the stud

H&R calls this the minimum but I think its just abuot where it should be

 

it gets 3.5 to 4 turns. too little. so on a 12x1.5 thread so to make 8 turns it would need another 5-6mm on the thread(7mm longer would be ideal), so I think I need longer studs.... know anywhere I can get this from?

 

hmm H&R is the only place I know of

you might want to try your auto parts store, they usually can order them and stuff, make sure to know how to convert metric into standard! haha they usually carry studs in standard sizes

 

called the lexus dealer... they don't know... but they told me to check if neural pitch was .509 and if it is there is a place where I can get it. Anyone know what this "neural pitch" is?

 

Neural

\Neu"ral\, a. [Gr. ? nerve.] (Anat. & Zo["o]l.) relating to the nerves or nervous system; taining to, situated in the region of, or on the side with, the neural, or cerebro-spinal, axis; -- opposed to hemal. As applied to vertebrates, neural is the same as dorsal; as applied to invertebrates it is usually the same as ventral. Cf. Hemal.

Neural arch (Anat.), the cartilaginous or bony arch on the dorsal side of the centrum of the vertebra in a segment of the spinal skeleton, usually inclosing a segment of the spinal cord.

I dont know about buying the studs by themselves- but using H&R spacers is a good thing to do.. many cheaper sets of spacers make alot of noise

I am running 10mm spacers on my Maxima in the front and I needed longer studs but a 5mm longer stud was long enough to give me sufficient turns over stock mine too were only turning 4-5 turns

 

nono!!! it's knurl

That refers to the part at the base of the stud that has some splines on it so that it can press and stay into the hub.

If you have enough room in the wheel, you can just change it over to some 7/16" x 3" studs, those are more readily available in the "knurl" you are looking for.

Just for your information, there is usually a .010" interference for proper fit, so a .509" knurl stud should fit correctly in a .519" hole.

thank you very much for the information. I managed to get H&R to sell me the studs (15mm over) without the spacers for 2.50 per stud.
