Modified IRS

I have never seen a picture of this irs on TCCOA or SCCOA so I thought I would post up. If you look hard you can tell it is MN12/FN10. It has some nice upgrades. The only thin i don't know why they didn't do is to add an extra mounting point to the upper arm. It also doesn't have a sway bar and I would add a cover brace or a billet cover.

Here you go:

Doesn't appear to from just the looks of me it looks to become an integral part of a tube frame/cage.
I'm thinking this is a lot closer to real "race car" stuff than it is to "street car that wants to be race car" .

The only thing I see that gets an honorable mention would be the heim joints.

Other than that I hope whatever it goes in is stripped down 'cause that one heavy piece. The geometry scares me too.

A few hard drag launches on an mn12 would eat those Heim joints, I'm afraid.

Probably be great on a 1000lb chassis, tho.
