So I decided to take sediciRich's advise and instead of going for long 45mm wobbly bolts I decided to convert to studs.
Here's the reason why:
click (thanks sediciRich).
Parts used:
- 70mm 9.9 tensile studs (20mm shorter parts which go into the hubs). FYI, H&R studs kit is 8.8 tensile.
- 28mm thread depth closed wobbly nuts (about 12 full turns to lock the wheels)
- 16mm billet aluminium hubcentric spacers
- Locktite head gasket black silicone sealant to keep the studs in place in the hubs (hope this will be enough).
For standard wheels I will be using either extended close nuts or standard size open ones. Unless off course standard wheels won't rub the arches with standard wheels on - yet to be checked.
I reckon that 54mm longs studs (70mm minus 16mm spacer I used) will be fine with no spacers and standard wheels?
Cheers,
Jack
