Difference in Suspension from series IV to V
Just wondering what the difference in the Suspension is from the 86-88 Sereies IV's and the 89-91 Series V's is.

Banned. I got OWNED!!!
There are 3 suspension from 86-91(or, 4 if the 'vert has a different one but doubtful).
base(86-8 4 lug, 89-91 GTU)
GXL(86-90 and 91 coupe)
T2(87-91 t2 and 86-7 sport, 88 gtu, 89-90 GTUs)
The t2 suspensionm appears to sit lower, then the GXL almost as low, then the base sits pretty high.
Since I keep all these parts on hand, me and a friend experimented one day.
We used a 86-8 base suspension(stock on his car for comparison). IT was an 88 SE 5sp. We installed an AAS GXL suspension, a 89-91 GTU suspension(before we realized they were the same) and a t2 suspension.
None of the suspensions altered ride height at all. THe gxl suspension seemed mushier(surprise, shitty AAS struts) the t2 suspension was slightly stiffer but not much.
We figured out that the ride height is much more a function of the weight of the car(year and options) than the suspension. There was no more than 1/2" difference between any of them, an amount which could be attributed to differences in wear between struts.

Take a peek in a factory parts fiche and see if there are different numbers for coupe vs vert suspension.

I've never had plastic endlinks fail on my S5 7, despite 11 years of regular autocross and track use, but I've had a number of metal end links fail (including ones from a rear bar of an S4)- usually due to rust, or the link rubbing on the bar or control arm attachment point when stock rubber bushings deteriorated, necking down the link till it failed.
Lighter, more effective, and more durable = win.

Wait, you have a coupe/vert? I have never heard of those....

Those "cheap plastic" anti-roll bar end links are also ball-jointed, making them more direct and effective.
