I've just finished the rear end mods on my car, and today I have had it wheel aligned and it passed fine. I have ten inch wheels with 7.5 offset. Plenty of dish. I reduced the rear about 40 mm each side. I went the easier way and cut the rear arm near the outer rose joint and rewelded it. It was easier but probably not cheaper. So I drove it 50 yards today for the first time. What a Adrenalin rush.
