i have my Steeda adjustable UCA ready to install. what is the best length to put it to? i think steeda says 8.34 for performance, but i want to make sure cause i don't wanna install it and get worse wheel hop. my cars stock ride height.

it's a hard question to answer...

essentially you are asking what the
pinion angle should be, with a two
piece drive shaft, aftermarket upper
and lower control arms.

i would probably start by measuring the
current pinion angle, install the UCA, then
set the pinion angle to match.

i'm interested in what others have to say
because i also, just installed the steeda
adjustable UCA.

the only reason i ask, is because steedas directions say to do a .10th shorter then factory for performance. i'm not too worried about the car handling like a lincoln, i'd rather fix the wheel hop. tomorrow if i dont have a different answer i'll just go with the steedas 8.34 or whatever it is.

sorry i couldn't give a definite answer, i
just installed a one piece drive shaft along
with the UCA and my setup is different.

you can't go wrong with the steeda
starting point.

what driveshaft did you install? i was going to order the shaftmasters one but i don't like the idea of an adapter plate.

i went with a dynotech, it also
has an aluminum adapter plate.

since lethal and brenspeed both sell
it, i figured it had to be ok.

just installed it, did the steeda recommendation of 8.36"

my god. i didn't think that out too well before i placed the jack stands. and the exhaust was a pain in the ass.

put the jack stands on the lca mounts. so when i broke the bolts loose the rear is just dropping forward in my way.so i had a jack under there on the pumpkin. couldn't get anything anywhere. + all mine and my dads tools are over my brothers house while we're building his 94 gt.

took it for a test run, and laid rubber down all the way thru second, no hop. gunna test more tonight, gotta head to work.

You can't set it to a specific length. Every car will be different, especially depending upon your suspension and driveshaft setup.

You need to get yourself a magnetic angle finder. Then you need to check your pinion angle. With stock driveshaft, you should be around -2*. For a one piece driveshaft, just a bit more.

This video will show you how to do it.
