[DeTomaso] Adjustable Rear upper a-arms

[Julian Kift]

Mike,

 

Rarely do I disagree with you, but..... I would counter your argument as false economy, you conclude that additional length is required in the upper a-arm to improve camber, but for $369 you get a relatively fixed 3/8" with the lengthened a-arms. Add in a pair of new upper ball joints at $350 as most prudent owners would do at that point and you've just spent what the all-in adjustable (and longer) units cost and they don't require the ball joint. 

 

I'm not talking the $1200 Pat Mical mod as discussed recently, but a simple outer heim joint a-arm of the type I have on both Pantera's like so...

IMO this offers far more rear camber flexibility especially for a low slung wide body Pantera. Furthermore Byers price requires you exchange in your current a-arms, whereas I purchased the above outright and could probably get some $$ back on my oem units.

I have never understood the desire to have adjustment at the upper A-arms.  Given that all the alignment adjustments are made below, you don't really need *adjustable* upper A-arms, you just need *longer* upper A-arms.  Longer arms will send the tops of the hub carriers out a fixed amount, and then you can tweak the alignment in the normal fashion with shims down below.

As far as I know, only Precision Proformance (and maybe Hall Pantera???) sells fixed-length extended A-arms.  They are much less expensive than the adjustable versions, use the stock ball joints, and do everything you need.  Very highly recommended. :>)
