I recently purchased the JBW replica Mamba wheels. The wheels look super nice but I have a problem with the lugs nuts that came supplied. They only go on about three turns before they are tight. Do I need longer studs or different lugs? Who has had this problem??

maybe both. depends on what you have now.

Hi mk2

I have the mambas. Albeit 12inch.
On the front standard 35mm studs I was only getting 3 turns.
The next length up on studs is 50mm which I had to use. these then poke through the centre too far to tighten up so I then needed 7mm spacers so that I gained 8mm of stud overall which was perfect.
The backs were fine on mine but I have the spaced drums as standard so will be different to yours.
Ball ache though! Good luck.

Nice wheels, are these 5 or 6 width inch rims?

These are 5x10" wheels.

I would be more inclined to avoid spacers on the front at all costs and shorten the studs instead. Spacers on the front cause bump steer and lower steering stability while increasing loads on the wheel bearings.

nope they do not cause bump steer. what they do do is change the King Pin offset which in turn increases the scrub radius which makes the steering heavier.

 

bump steer is caused by the motion of the suspension through its travel  (normally in Bump) causing the wheel to move about the king pin axis (steer).

 

yes spacers do increase bearing loads.

You're right, that wasn't the right term. What I meant was it increases the leverage of the road over the steering and when you hit a bump, you have in effect less self-centering because of the increased scrub radius which you feel as the wheel being pulled out of your hands.
