Front Roll Center Mustang II

[wiedemab]

I've tried to search for this, but haven't had any luck. Again, I apologize that my current project is more "Street Rod" than "Pro-Touring" ('52 Chevy Pickup), but I'd still like it to drive/handle as good as it can (within reason/budget).

Anyway, does anyone have accurate lengths, positons, for a-arms, uprights for a stock mustang II front suspension.

Basically I'm wanting to calculate my front roll center at ride height so that I can try to position my rear roll center height appropriately (4-bar w/ panhard). I guess I could just measure, but I wasn't sure how accurate that would be.

I'm still learning suspension technology Doing a lot of reading on this forum.


I'm an ME, but didn't have room in my school schedule for Vehicle Dynamics (I should have made room). I think I'm going to pony up the $$$ for RCVD by Milliken and read away!

Thanks for any help!

Download the Performance Trends Suspention Analyzer demo. It's free, and has a Mustang II susp. in the samples. It will give you all the locations for everything. BTW roll center ht. is .89

I'll take a look at it.

Am I correct in saying that by going with 2" dropped spindles - I have lowered the FRCH by that same amount? Essentially causing my FRC to be below the ground at static ride height, but migrate upward during bump crossing zero (ground). Is that going to be a huge issue. I'm not going to be road coursing this thing (it's heavy old truck), but I would like it to handle half way decent.

Also, I have read (in my limited reading) that as long as the rear RRCH is above the FRCH that's a good thing. Is this always true. I'm also trying to position my rear panhard which will define my RRCH.

Side Note:
I'm going to buy Milliken's RCVD for X-mas for myself. Hopefully that eliminate some of my questions, but I appreciate any help in the mean time.

Thanks,

The Perf Trends software file was done by a Ford Engineer, it is accurate.
RCH is .89" above ground with a 73.5" circumference tire.
1" of dive puts the RCH at ground level.
At normal ride height, the lower ball joint height is 8.4"
