Forte has a mod to add adjustment to the rear IRS UCA and LCA. According to his website it makes the rear end alignment easier to do. I am waiting on delivery of other rear end IRS before I can proceed so I thought of sending the arms off for the mod. Has anyone done this? If so was it worth it? How long did it take?

I helped align an IRS car a few years ago and I think the adjusters are definately worth it. W/o them you need to pull the bolt out that attaches the rodend to the frame, rotate the rodend, and then put the bolt back in. Not have done an irs w/o them, I can't say which way the control arm tends to move when you pull the bolt, but I don't think it stays in position.

Definitely worth it. His machinist put an extra set of holes in my lower arms that I was not crazy about, but the adjusters make the alignment process a breeze compared to trying to having to re- install the shims after adjustment.

The lower control arms are a pain to adjust, there's no doubt about that. Once you properly set toe and track width, you never have to do it again.

Waiting for Mike's Infomercial to follow. My notebook wifi took a dive, don't make me actually have to go surf and find the website on this desktop. There's so many pinterest bookmarks I can't see the screen.
I can't wait.

I wish I would have gone with them. Getting someone to really take the time to align it properly is hard.....at least in my area. The guy that did my paint finally got mine right. He read numbers and I fought with the shims and control arms. He just kept shaking his head saying "why they'd make it like dat"? Also, Mike Everson has a very good method to get things started. Search the other site for his posts.

I dont see the benefits, you setup the rear alignment once then your done. So unless you track the car and need to make adjustments to the alignment, you are paying a large lump of $$$$ for a one time use. Making adjustments even with Forte's adjusters would require adjusting the shims to prevent too much side loading on the rod ends.

You do the alignment with no shims in place till you have it set. Then shim the tie rods. These can be done easily except the cuts to the control arms have to be straight so the adjuster sits flush. This is where the expense comes in
