Wheel Bolt Circle

[KevinM]

Does the Hurricane with an IRS use different bolt circle wheels front and back?

The front end seems to be GM based, which would be a 4 3/4" bolt circle.

  Ford rims front and back, both sets are 4.5 inch bolt circle.

Mike,

So they use a Ford spindle and rotor with a GM caliper on the front?

Correct.

All of our kits ship with 5 lug 4.5" ford bolt pattern in the front and rear (both the 9" and IRS). It is very common to use the GM Metric caliper with the spindles we use. Pads and aftermarket parts are inexpensive and readily available.
