Harrison builders - question on stud patterns

[400TT]

We did it on his previous version front suspension. Our front suspension has fabricated upper and lower "A" arms and at that stage using HQ stub axle. Warwick now uses fabricated straight lower arm with control rod(z bar) and commodore hub & upright assembly and that upright to upper "A" arm adaptor.

The advantage of Skyline uprights is:
* Less unsprung weight
* Skyline brakes fit straight on, so get 300mm rotors & 4 piston calipers. Skyline GTR V-Spec also had larger brembo brakes.
* Easier to fit abs sensor, but now with that Commodore upright, it would have abs sensor mounting, if it's a late enough model.

The disadvantage of Skyline uprights:
* Work & expense involved in fitting it.
* More difficult for parts e.g. wheel bearings etc.

For a street driven Cobra, Warwick's standard setup with Commodore brakes etc is fantastic bang for the buck.

We use one of the rear Skyline ABS sensors for speedo and use the front and rear sensors for traction control. Well that was the plan, but the version of Autronic SM2 ecu we have is buggy, traction control doesn't react. We can see the ecu detecting the wheel speed difference between front & rear, but ecu does not try to correct it be retarding the ignition etc. Didn't bother with abs, but people have done it.
