Has anyone fitted these to a 411 ?

I have only fitted spacers of almost this thicknes (1 inch) on a 993. As the drive characteristics changed, I removed them.

A thought, Greg: The spacers are made from aluminium. If you look closely on the photograph, at the holes where the hub bolts go, imho there is a serious weakness, there is not much aluminium left.
Risk for failure? 411 are quite heavy cars.
Be aware that the load on the components of the steering and suspension will increase quite a bit. Also be aware that the steering geometry will change, as you are changing the width of the track by 2,5 inches ( 6.35 cm - sounds more in centimeters!

)

The six series alloy of aluminium at that temper is about the same strength as mild steel.

I was actually only thinking of adding them to the rear. As you say, the front may cause problems with steering and fouling. Bristol Cars actually fit a wider rear axle as an upgrade, so hopefully it will improve the ride ! I will let you know :-)

Wider Track Rear Axle

Eliminates narrow-tracked appearance at rear making the car look far better proportioned and elegant as well as sporty. Widens track by more than 2 inches improving stability, adhesion and ride comfort.

Maybe just these at the front ?

I wouldn't make any changes at the front. Bristol supposedly did an enormous amount of work to perfect the front suspension, steering geometry and ride. By making this change you risk spoiling that.

Also, you would effectively reduce the wheel stud thread by 3mm. Given that Bristol specify wheel nut torque of about 90 lb/ft, shortening the studs may not be wise.

Which wheels do you have on your 411? (steel or Avons?) and what tyre size and pressure? - these can make a big difference
