problem:
I am looking to put fd wheels on my fc. I am aware of the safety issues with spacers. Simply put if i use the spacers with a whole new set of studs built in there is a chance of them ripping out/apart. On the other side if i use longer stronger aftermarket studs and 25mm non-functional spacer there is a greater chance of the studs breaking due to the increase in length and the new sheering surface introduced by the spacer.

solution:
i am thinking of going with the longer stronger aftermarket studs and the non-functional spacer. However rather than just placing the spacer between them and bolting it on, I was thinking I could use some 680 LOCTITE hightemp/high viscosity retaining compound to permanently attatch the spacer to the fd wheel, therefore eliminating the second sheering plane. The loctite has a sheer strength of 4000 psi.

If my theory is correct the majority of weight/force is put on the hub and studs so the loctite should be enough to hold the spacer to the wheel and provide zero movement between them, therefor creating a situation juts like stock(there will be only one sheering plane located at the base of the stud).

I would really like some opinions becasue this is my first attempt at anything like this and I am trying to go the safest route. Also if this is a viable idea, can anyone reccomend me some aftermarket stud companies? So far ive heard of moroso and ARP.
Thanks in advance for any and all help.

p.s. i posted this in wheel/suspension ect but that seems like a dead forum compared to the 2nd gen forum.

yeah look dude, loctiting the spacer to the wheel wont do jack to help your studs.. I'd be extremely suprised if it actually held the wheel to the spacer at all.. Not saying it wouldn't... just saying i'd be VERY suprised if it did, there is alot of load in that area of the car..

something you CAN do though is to make the spacer hub-centric on one side(the hub side obviously) and a exact copy of the hub on the other side (the wheel side, duh.. ).

That is about all you can do. But you will still have the problem of having longer studs which in turn means a greater bending moment happening on 'em. You can't get around that..

IMHO, I wouldn't use longer studs.
Making a spacer plate as above but with new studs threaded in it would be a much better idea. Just make it out of a stuitable material and you wont have any problems..

Im startin to think theres no really safe way to put these wheels on my car. Im probably gonna just use the H&R spacers for mustangs with some hubcentric rings. i mean im not doing auto x or anything just some spirited street and highway driving under 100mph. All the stories of them ripping apart has been after or during some sort of track use, hopefully ill be fine.

You said they were aluminium, aluminium fatigues... so it's only a matter of time..

hmm just rethought that...

Your not saying the spacer will explode? just the wheel studs?

then dont use extra long studs.. have the threaded into the spacer..

ddub

Hubcentric...

If i am using studs threaded into a spacer then the weight/force is being put on the aluminum spacer. If I am using longer stronger studs and attaching the spacer to the wheel then the weight/force of the wheel is being placed on the studs. the problem with this is that there will be 2 points on the stud to flex rather thna one. If i attach the spacer to the stud then their will be only one flex point at the base like stock. The only problem with my theory could possibly be strength of the bond with the loctite. It says it has a 4000 psi sheer strength, so i figure it will hold since there is no force being applied in a proper way to seperate them (eg between them or down at their meeting point) H&R makes these kind of spacers for up to 20mm so i figure the idea itself is safe, and the loctite and stronger studs provides an increased level of safety.

What i really want to know in addition to the validity of my theory is what other people have used to put fd wheels on their fc and what aftermarket stud companies are good. Right now im going with ARP.
