Does a drum to disc conversion increase or decrease wheel offset?

[TheMonkey]

Okay... well I spoke to the wheel guy and he said even with the switching brakes situation he said the difference would probably be so minimal that he would still recommend the 18x8 with 4.5BS and 18x10 with 5.75BS.
....

i would be very cautious about just listening to what a wheel guy says.



consider installing the brake conversion first and measuring your scrub radius, and determine your offset that way.

simply referencing back to stock scrub radius may not be ideal, as scrub radius was not as crucial with skinny tall tires from the 60's. with wide radials on 18" rims, proper scrub is waaay more important.

here's a discussion on a method of measuring scrub radius and why it's important. consensus seemed to be 1/2" to 2" SR.
