Harrison Cobra Rear Wheel offset

130mm sounds about right for the distance from the bolt up face to the outer edge of the rim. I had mine made up to 125mm for this measurement. Difference can be accounted for in that my rims are 16" and the tyre bulges about 5-10mm from the outer edge of the rim. Your 18"s will have much less bulge, probably about 0-5mm.

As I understand it, OFFSET is the distance from the centreline fo the wheel to the outer or inner face of the wheel. This will be different depending on the width of the wheel. I stopped using the term with wheel manufacturers as each seems to have a different interpretation.

What you guys are describing is "wheel backspace".

See if you can give Warwick a call to confirm.

Warwick is contactable on mobile only these days. The number is on his web site: Cobra Kits: Home

Sorry did not read the post clearly. Yes it is frontspace, the remainder is backspace.

Offset is is the relationship of the bolt up face to the centreline of the wheel.

Good advice from Merv. Warwick should by able to give you his recommnedations. I would contact Warwick first and then confirm the measurements yourself taking into account your wheel alignment and suspension travel.

Hey HP
PM me and I'll send you some wheel offset charts, as well as what Warwick advised for mine, with 9's on the front & 10.5's on the rear
