Is it safe to fit alloys purely on the strength of the bolts? Do cars that use studs and nuts do this anyway?

[deano01]

Had rear wheels on the front of mine before new wheels fitted last year. I believe I had 205 's on the front. No spacers and no rubbing.

im on 225F 245R and the fronts rub on full lock. 215 seems to be the max altho every car is slightly different as the hand made tolerances arent tight

[gaffer1986]

I don't mind the rubbing so much on full lock as I can avoid full lock fairly easily. More interesting in changing the spring rate and scrub radius due to a different offset.

[gaffer1986]

Fronts are e26 rears are e36 so if I get a 10mm spacer for the rear wheels they will also be e26 which should keep the scrub radius the same, spring rate will be slightly lower as there would be an extra 20mm more leverage from the extra width of a 215 tyre. The hub spigot is around 15-16mm deep so a 10mm spacer will leave me on 5-6mm spigot to mount the wheel.

 

Question is, would you trust a wheel on only 5-6mm of spigot, I not sure how important the hub spigot is for securing the wheels or if the bolts can take most of the force. Or am I doing too much research?

Upon doing more research it appears that the hub spigot only acts as a locator and is not load bearing. The wheel stays in place due the friction between the wheel and hub face cause by the wheel bolts.

Based on your other posts, I see this ending well.....

[gaffer1986]

Lol, I may go to all this trouble and prefer standard wheels. I'm going to do a brake test first though to see how much quicker I can stop with more rubber.

[gaffer1986]

Ps: I'm getting there, I managed to fix my window Main concentration at the moment is headlights hopefully some time this weekend. Then I'll give wheels my full attention. I picked up a set of standard wheels from Birmingham Monday so I already have them. Just need spacers which I have an idea about now.

I run 205's on the front, on rear wheel set up, they have never rubbed, tyres do look a bit euro look as in stretched on rubber, I will say the car handles a bit better on a good road, but in b road areas and country roads, its both hands on the wheel, it tram lines like hell, at higher speeds it can scare the pants off you, but thats the reason why I bought the car, I find these cars a little on the dangerous side, wet leafy lanes or rain sees you clenching everything, great fun

You would love a 4c then

[gaffer1986]

I certainly love the look of the 4C, saw one for real the other day and dribbled!

For how it looks you can forgive it!
