Help! Do I need adjustable LCA's?

08SilverStang · 10-09-2009, 10:39 PM

Ok, I have the Eibach Sportlines on my car. I feel driveline vibration, and I am worried that I am prematurely wearing out the drivetrain without having Adjustable LCAs. Can you guys help me out and give me some advice on what to do. Do I need adjustable LCA's, or UCA's, or both. And what will they do?

hmmmm.... have the H&R SS wich is lower than the sportlines .. no vibration ........ Check to make sure nothing is rubbing first.. then if anything get an adjustable pan hand bar !

So you don't have adjustable LCA's or UCA's? I actually do have an adjustable panhard bar, I forgot to put that in my Sig!

you have a one piece DS....makes a big difference (if balanced correctly) in driveline noise and vibration

an ADJ panhard bar will center the rear of the car with a drop and bigger rims.....

most people get one or the other to get their pinion angle in the right spot. Usually you wont need both to be adjustable.

Its easier to adj the LCA's while on the car then the UCA (only one).

Have you measured your pinion angle?

No I have not measured the pinion Angle and I have no clue how to

OK its not too hard but I am moving this to the handling section for the suspension guru's to take a better crack at this........when do you feel the driveline vibrations? WOT? cruising?.....the factory 2 piece is crap and noisy

EDIT: BTW I love the stance on your car in the sig....any closer pics and ones that show the back end of the car?

08SilverStang · 10-09-2009, 11:16 PM

Thanks for the compliments man! I think that I may have some pics of the back of the car...

I have only noticed the vibration at like WOT, I would love to put a once piece DS in it

Ok here is a picture of the rear... this is an old pic and the tailpipes needed to be adjusted here, but I have fixed them now, they dont stick out so far now. I one or two other pictures I will post

nice ride man and at WOT the 2 piece DS can have a little slop and even make it harder to shift cause of the factory hydramounts for the motor and the trans and DS move when torqued over......lets see what others have to say....might take a day or two as it is a Friday night and its time to party!!!!! I am subcribed to this thread and will link some threads about pinion angle and how to measure in a day or so....

take care....and welcome to the forum

Thanks bro! Gosh I wish I had a supercharger on my car, your car must be a beast with that on it!

I really appreciate all the help with the pinion angle. Yeah I know that most guys are not on here on Friday night, so I will check back tomorrow, thanks for your help
